Editorial Reviews

From the Publisher
Praise for The Comet’s Curse

“Grabs readers’ attention with the very first page and never lets go…. Both a mystery and an adventure, combining a solid cast of characters with humor, pathos, growing pains, and just a hint of romance, this opener bodes well for the remainder of the series.”—Kirkus Reviews

“Part space opera, part mystery, the story draws readers in from the beginning with well-placed hooks, plenty of suspense, and a strong premise.” —School Library Journal

Children's Literature - Judy Silverman
This is a continuation of the "Galahad" series, in which Earth is doomed, so a carefully-chosen group of 251 teenagers are sent off in a rocket to a distant galaxy. There, they will find a new earth, and carry civilization—well, young humanity's version of civilization—to their new home. On the whole, they are doing pretty well. Triana, the captain, is getting a little more comfortable with her position of authority; Lita, the head of the hospital section, is more able to cope with the crew's generally minor ailments. Two of the young men—Bon, a taciturn Swede who is in charge of the plants that will feed the entire group, and Gap, who is a member of the Council helping to run the ship, and is a good deal more talkative—find themselves attracted to certain female members of the crew! Do the girls return their feelings? Within a few pages, we find that they probably do Without having read others in the series, readers may feel lost. There is more talk than action here, and in fact there is a little too much talk/meditation—readers are being told about things rather than being shown them. The book is readable, remarkably gripping at times, but on the whole disappointing. Reviewer: Judy Silverman
Kirkus Reviews

The fourth installment in Testa's teen saga of space exploration, theGalahadSeries.

A year into their mission to establish a new home for humankind beyond the edge of the known universe, the crew of the Galahad has had their share of trials. There hasn't been much time to deal with the usual issues of teen angst and first loves, but that doesn't mean these aren't part of the mix. Dealing with relationships is the central issue in this outing, from friendship to love to loss. Most importantly, how does the team build a relationship with a new species? Vulturelike creatures appear, pace and then attach themselves to the outer hull of the ship. Are they a threat? Mere observers? Perhaps they are messengers...but from whom and from where? The Council has to put aside their personal considerations to resolve the best course of action—for the ship and the crew, their mission and all that remains of humanity. Slow to start, this book regains momentum halfway through to race toward an open conclusion.With only two more books in the series, the next installment should pick up the pace.

Dedicated fans of the series will appreciate it, but it probably won't win new converts.(Science fiction. 12 & up)

Read an Excerpt


There was no sound in the room other than muted sobs. No laughter, no whispers, no private conversations. More than two hundred teenagers, crammed into a sterile space, yet completely quiet. It was an unnatural silence, which added to the somber mood. Occasionally a cry escaped from one of the teens, which provoked a similar response from another, then another. Then once again the deathly veil dropped, and silence reigned.

The shroud-covered body lay alone on the table, identity disguised. It held the attention of every person in the room, for it represented what none had believed possible.

Galahad’s first death.

A crew member separated from the crowd and trudged up the steps to stand behind a hastily-arranged podium. Choking back tears, they spoke quietly, reciting memories of their late friend, offering words of encouragement in a vain attempt to make it seem that everything would be okay.

Nobody responded. They stood silently, most with hands clasped behind their backs, filling most of the available space in the Spider bay of the ship called Galahad. As the speaker walked slowly back down the stairs, music began to drift across the room. It brought about a fresh wave of tears.

Silence dominated again. Then, slowly, the crew members began to disperse. One by one they approached the body; some reached out and placed a hand upon it, others simply stared. After pausing for a moment, they shuffled past, across the vast hangar, and out the door. It took almost thirty minutes for everyone to pay their respects individually. In the end, five people were left, huddled together, not wanting to believe it could have happened, not wanting to say goodbye. They embraced, then together approached their fallen comrade and placed upon the shroud a bouquet gathered from the ship’s farms; not true flowers, but the closest symbol they could manage.

A minute later they convened in the Spider bay’s control room, sealing it off, and stared sadly through the glass. With a spoken command, a door opened in the hangar, exposing the room to the icy vacuum of deep space. Starlight cascaded through the opening. It was a simple reminder: We are far from home.

There was hesitation, a collected feeling of loss, and a reluctance to let go. The next move would send the body into space, to drift for eternity. No one wanted to move, to take the next step, to banish their friend to the depths of empty, lonely space. But at last the word was given, and the ship’s computer began the final sequence.

The robotic arm, until now concealed below the table which held the body, extended toward the bay’s open door. With a gentle shove it was done; the shroud covering the body fell away, revealing a cocooned human form, layered in specially treated wraps. It cleared the opening and began its endless journey. Within a minute it had receded from view, first a small white object slipping away, becoming a faint pinprick of light, and then gone.

Once again the five companions in the Spider bay’s control room embraced, allowing their grief to mingle, physically holding each other up. They remained that way as the bay’s outer door closed, blocking out the starlight, sealing them once again into the warmth of their metal nest.

And then the scene froze…and faded away.

It was a familiar smell, but Alexa Wellington couldn’t place it at first. Still disoriented from the deep sleep, she lay on her bed and kept her eyes closed. The misty line between wakefulness and dreams had dissolved, but once again the vision had been so strong, so intense, so…real…

She was, as usual, reluctant to let it go. In the last six weeks her dreams had become more and more vivid. They didn’t come often, perhaps only two or three that she could remember each week; but they were unlike any dreams she had ever experienced before. For one thing, there was no dream-like quality to them. In one of her quiet conversations with Bon Hartsfield, Alexa had likened them to mini-movies, only with the screen inside her head in full 3-D and high definition. Until she awoke and opened her eyes, her mind would not interpret them as anything except real.

On top of that, they were complete dramas; they had a beginning, middle, and end, unlike the typical dream which generally jumped from place to place as well as backward and forward in time. These were stories that played out as if scripted. Often they were quite pleasant, while others were very unsettling. This particular dream was the most disturbing yet.

Taking a deep breath, Alexa opened her eyes. Other than the soft glow from the computer monitor across the room and the faint emergency light above the door, the room was dark. She could just make out the still form of her roommate, Katarina, sleeping. All was quiet. The scent that had greeted her upon waking was artificial; Katarina had apparently dialed up her favorite sleep aid, a soft fragrance of lavender that seeped through the ventilation ducts.

Alexa resisted the urge to glance at the clock, for she had found that her mind would then only focus on the time, mentally calculating how long it would take to fall back asleep. It might be midnight; it might be 5am. She didn’t want to know.

Of course, concentrating on the time might distract her from the troubling dream that had unfolded minutes ago. The nightmare’s tragic setting was only one concern; the fact that her dreams had lately started to come true was terrifying.

She took another deep breath, held it, and then slowly exhaled. Try as she might, she couldn’t shake the vivid image of the deep-space funeral. Who had been lying beneath the shroud? Who were the friends clustered in the control room, grieving together? Their faces were obscured, their gender a mystery. She had felt that they were somehow close to one another – but that didn’t help; there were 251 teenagers aboard the ship.

Another thought occurred to her: should she tell someone? If indeed her dreams were somehow portals to the future, allowing her to glimpse ahead, was it irresponsible to keep this vision to herself? On the other hand, what purpose could it serve? The dream had given no indication of the cause of death, which meant that realistically no preventive steps could be taken. If word leaked out that Alexa was now predicting death for one of the crew members…

And just who exactly would she tell? Triana Martell? That would be the obvious choice; the ship’s Council Leader would be understanding, and would treat Alexa with respect. But Triana had so many responsibilities, and dealt with more pressure than most teenagers could imagine. Why add to her concerns when there was nothing that could be done about it?

Lita Marques would also be very understanding, and, as Alexa’s immediate supervisor in Galahad’s clinic – lovingly referred to by the crew as Sick House – knew her better than anyone. Lita was a good friend, a good listener, and easily the most compassionate person Alexa had ever met.

And yet was it a good idea to burden her with this information? A mere eight weeks ago Lita had operated on Alexa and removed her appendix. In fact, the surgical procedure had inadvertently brought on the dream visions that now plagued her. Alexa had not awakened immediately after the operation, and instead had briefly lain in a coma. Something had happened to her during this unconscious stretch, something nobody could quite explain.

Although she had done nothing wrong, Lita blamed herself for the frightening turn of events. Alexa couldn’t see troubling her with this new development.

Then there was Bon.

The quiet, somber Swede had few real friends aboard the ship. He kept himself busy with his work, running the agricultural program within the two massive domes that topped the spacecraft. Few people had ever been able to get emotionally close to him. And yet, over the last few weeks, he and Alexa had connected.

It began with a visit he made before she was discharged from Sick House. During their brief conversation she realized that he had sought her out because of something they had in common: both were experiencing bizarre mental flashes that had altered their worlds.

For Bon it was his tenuous connection with the alien entity that the Galahad crew had encountered while zipping past Titan, the mysterious orange moon of Saturn. That connection had eventually saved the ship from certain destruction within the debris-strewn minefield known as the Kuiper Belt. For Alexa it was her sudden prescient abilities.

It was a bond forged of their uniqueness. As Alexa had said to him recently, “We are the ship’s freaks. Nobody else could possibly understand.” Bon had scowled at hearing this, but had offered no argument.

She had shared many of her dream visions with him over the weeks, but not all. How would he take the news that a death aboard the ship might be imminent?

She decided to wait.

With a sigh she gave in and twisted her head to look at the clock, just as the time clicked over to 1:55am. “Go to sleep,” she whispered to herself.

Deep inside she knew it would not come easy.

The Dining Hall on Galahad was packed. Triana walked in at 7:15, late for her breakfast meeting with Channy Oakland and Lita. The three girls made it a point to start the day together at least once a week, occasionally to discuss Council business, but mostly for social reasons. She scanned the busy room and spotted Channy waving from the far corner. Channy was easy to pick out of most crowds; all one needed to do was look for the brightest t-shirt in the room. Today’s choice was hot pink.

“Sorry I’m late,” Triana said after loading a tray with some fruit, an energy block, and simulated juice, her usual breakfast combination. “It took me longer to answer emails than I expected.”

“Everything okay?” Lita said.

Triana nodded as she sipped her juice. “Lots of questions about what’s going on back home. Not that I could really offer much information.”

“It had to happen eventually, right?” Channy said, a grim tone overriding her usual upbeat British inflection. “I mean, I’m surprised we kept contact for as long as we did.”

“It’s still tough to swallow, no matter how prepared you think you are,” Triana said.

Lita looked thoughtful. “So I guess we can officially declare ourselves out of the nest. No replies to our messages must mean that Galahad Command has closed for good.”

The three girls reflected on this for a moment before Triana said, “It’s not that we really needed their help for anything in particular. With Roc we pretty much have the technical know-how. It’s the…uh…”

Lita finished for her. “It’s the emotional tie.”

“Yeah.” Triana looked around the room. “Although the crew seems to be in pretty good spirits. I can’t remember when I last saw this place so busy in the morning.”

Channy laughed. “It’s because of this.” She held up a small bowl with a sticky residue around the insides.

“What’s that?”


Triana raised her eyebrows. “You’re kidding. We have oatmeal?”

Lita smiled. “Bon impresses again. He told a few people that it would finally be ready, and the word spread like wildfire.”

Turning to look over her shoulder at the serving line, Triana said, “Why didn’t I see any?”

“Because it’s all gone, that’s why,” Lita said. “I don’t think anyone was prepared for the rush.”

“I got here at 6:45 and scooped up one of the last bowls,” Channy said. “Sorry, I guess I should have saved you some.”

It was Triana’s turn to chuckle. “Don’t worry about it. I’m sure I’ll have plenty of chances over the next few years.” She looked around. “Who knew that oatmeal could bring so much joy?”

“If you ask me,” Lita said, “it’s not simply the fact that we have any particular new food. I think it’s simply change, and that’s something this crew could use.”

“What do you mean?” Channy said.

“It’s not healthy to fall into a rut,” Lita said. “This is just my opinion, of course, but we could all use a shake-up in our routines. Tomorrow is the ten-month anniversary of our launch, and besides a few dramatic moments, and the switching of job assignments, we have pretty much all fallen into the same patterns, day in and day out.”  She looked at Channy. “It’s no different than what you preach to us every week in the gym, about alternating our workouts. After a while your body adapts, right? It’s not as effective.”

Channy nodded. “Right. But you’re talking mentally?”

“I’m talking about all of it: physically, mentally, emotionally.” She indicated the food dispenser line. “A new food choice is a little thing, but look at the reaction. It’s a welcome change; not all change is embraced, but it’s almost always good for people.”

Triana smiled. “Any suggestions, Doctor?”

Channy piped in before Lita could answer. “Oh! I know! What if we had something like, I don’t know, um…okay, how about ‘Shake It Up Day,’ or something like that? You know, everyone has to do everything differently for one day.”

Lita’s laugh was gentle and pleasant. “I know that you love to plan special events, Channy, but I wasn’t thinking about just one day. I’m talking about a lifestyle adjustment.”

“I know, but at least it would bring it to everyone’s attention.”

Triana shrugged. “I’m probably the biggest creature of habit on this ship. I’m pretty sure it would do me some good to mix things up a bit. I don’t know if we need a special day dedicated to it, but it’s something that we should discuss in a Council meeting.”

Channy grinned. “Just don’t forget about tonight.”

Her two companions went through the motions of adjusting the items on their trays, neither making eye contact. Finally, Lita said, “Tonight?”

“Oh, stop pretending you don’t know,” Channy said with a huff. “The Dating Game? This evening? Auditorium? Big fun? Remember?”

Lita and Triana looked at her, then at each other. Triana kept quiet, leaving it up to Lita to respond again. “I’m pretty busy with reports this week.”

Channy crossed her arms. “It’s one hour out of your life, Lita.” She shook her head at both girls. “I swear, you two are the biggest wet noodles I’ve ever met. Would it hurt that much to put yourselves out there?”

Triana at last broke her silence. “I know you really want us to participate, Channy, but maybe next time.” She offered a wry smile; Channy returned a pout.

“Fine. You could at least stop by and be part of the audience. I promise I won’t bring you up on stage. But I could use some more bodies in the crowd.”

“I’ll pop in for a few minutes,” Lita said.

“I’ll do my best,” was all that Triana offered.

For the next ten minutes the conversation drifted through a variety of topics, mostly with Channy’s enthusiastic comments, Lita’s thoughtful responses, and an occasional observation from Triana, who often chose to listen and quietly consider. During this time the room began to thin out, as more and more crew members cleaned up their tables and set out on their daily duties.

Galahad’s crew worked in six-week shifts within the various departments on the ship, before rotating into a different assignment. It was understood that this would allow each person to become proficient in many areas. Along with the advanced schooling that accompanied their work, the idea was for Galahad to have a seasoned, well-educated crew when it arrived at the Eos star system, their eventual destination.

At any given time a group of about thirty people were on a break from work, but even then their education continued. Many found that the break only led to boredom, and when their next assignment arrived they gladly returned to the rotation.

Lita stood, stretched, and picked up her tray. “Back to work for me. Anything exciting for you guys today?”

“I’m going to ask Bon if we can clear a path around the outer perimeter of Dome 2,” Channy said. “A few people in the afternoon workout group suggested that it might be more fun to run up there. It would be more like running outside. I think they’re very tired of the treadmills.”

Lita laughed. “Good luck. If I hear the walls shaking today I’ll know that you asked Bon.”

“I know he’s very protective about his crops,” Triana added, “but that’s actually a pretty good suggestion. Let me know if you want me to go with you.”

“What about you?” Lita said. “What’s your day like?”

Triana stood and pushed back her chair. “This will be an interesting day in the Control Room. We are officially shooting out of the Kuiper Belt now, and I’ve heard some rumblings about what might be on the other side.”

Channy sat still, looking up at the Council Leader. “And what do you think is out there?”

“A whole lot of nothing.”

“Just empty space?”

“Just empty space,” Triana said. She waved goodbye to Channy, and walked toward the door with Lita.

As they exited into the curved hallway and prepared to go their separate ways, Lita looked into Triana’s eyes. “Do you really believe there’s nothing outside the Belt?”

Triana sensed the anxiety in her friend. “Honestly, Lita, I have no idea any more. It’s getting to the point where nothing would surprise me.”

“Bon and Alexa seem a little worried about it.”

Triana sighed. “I know. But what can we do?”

Lita didn’t answer at first. Then, with a smile, she said, “We’re tough. We can handle anything, right?” She turned and walked toward the lift.

Triana bit her lip. For two months she had wondered what they would be facing when they shot out of the minefield of debris that circled the solar system. Soon they would find out.

The Science Behind Galahad

Volume 1: Artificial Intelligence

Hi. Dom Testa here. You’ve got your eyes trained on the first entry in a brand new series of articles that I’ll be writing, and I’m excited about it.

You see, as I’ve spent the past few years writing the Galahad book series—which is about the ongoing adventures of 251 teenagers who live aboard a spaceship destined for another world –I’ve found myself increasingly interested in the science that is at the heart of what is technically science fiction. I wonder: How does artificial gravity work? What is the technology that allows Gap Lee to be such a good Airboarder? How does NASA make use of solar sails in space travel, and what really happens when the Earth passes through the tail of a comet? And when I deliver presentations at schools or talk with fans out on the road, I’ve found that they often wonder the very same things.

So, in an effort to satisfy my curiosity and yours, I’ve decided to explore some of those topics in greater detail. With each volume I’ll tackle a scientific phenomenon of some sort and take it apart, bit by bit, until we all understand it a little better. It’s the science behind the Galahad series, and I’ve got a sneaking suspicion that it’s going to be a whole lot of fun. Let’s dive right in, shall we? First up: Artificial Intelligence.

“Open the Pod Bay Doors, HAL”

The term ‘Artificial Intelligence’, or ‘AI’ for short, dates way back to 1956, and the man who has long been credited with dreaming up that nifty little phrase is a computer scientist named John McCarthy –still alive and kicking as I write these words, by the way. Good for him. Anyway, the most basic technical definition that I’ve found is this:

Artificial Intelligence

‐noun; the capacity of a computer to perform operations analogous to learning and decision‐making in humans

Or to boil it down even further: computers who think and reason like humans. Hmmm.

The first time that I remember being introduced to the concept of AI was in Stanley Kubrick’s brilliant movie, and the Arthur C. Clarke book that accompanied it, 2001: A Space Odyssey. It was produced so long ago (1968) that the year 2001 must have seemed impossibly far away. In 2001, a spaceship sent to investigate one of Jupiter’s moons is controlled by the HAL 9000 (known simply as ‘HAL’), a computer that talks and thinks and maintains all of the ships vital functions. Incidentally, four decades later a much cooler computer would appear aboard a much cooler ship and serve much the same purpose –but more on that later.

2001 wasn’t the first time someone had dreamed up this idea of a sentient computer – in fact, Clarke himself had been writing stories about such things since the 1940s – but it was the first time that the idea showed up on my radar, and I’ll bet I’m not alone. That movie left an indelible impression on generations of filmgoers as HAL developed an agenda of his own and then executed it, all the while explaining his actions in a very calm, very creepy monotone voice.

Also in the late 1960s, the television show Lost in Space featured a robot –aptly named ‘Robot’ –that displayed its own form of artificial intelligence (and which also contributed the phrase, “Danger, Will Robinson!” to pop culture history). It was the very definition of cheesy TV, but I loved that show. Later, in the 1980s, the film Blade Runner–also based on a famous science fiction story, this time by eccentric author Phillip K. Dick –featured cyborgs that had gotten out of control and gone on a killing spree. It was a blockbuster hit with big movie stars and dazzling special effects that became something of a cult favorite over the years. And to some degree, there are lots of books and movies with similar themes dotting our cultural landscape. The Terminator and Star Wars franchises both feature a heavy dose of out‐of‐control androids or cyborgs, as does The Matrix trilogy. Some even argue that Frankenstein, written in 1818, deals with issues of Artificial intelligence in its story of a monster created from spare parts in a madman’s laboratory. But is that all there is to the idea of Artificial Intelligence? Fictional computers run amok and bent on overtaking their human counterparts?

Hardly. Fact is, the real world of AI is just as spectacular –but much less menacing.

A (Very) Short History Lesson

Once the field of Artificial Intelligence began to take shape, it wasn’t long before scientists from all over the world were raising the bar –and raising the stakes. The U.S. Department of Defense, which oversees the military, directed millions of dollars toward funding research, and other countries followed suit. Optimism ran high that within the span of a few decades, machines would possess the ability to cognitively perform many of the same tasks that humans do, and perhaps more. The train of innovation charged ahead…

…right into a brick wall. By the 1970s, the progress that was being made in the field of AI was not up to par with the lofty expectations that had been set for it, and some countries, including the United States, cut most of their funding for AI‐related projects. This became known as the first (but not the last) ‘AI Winter,’ where the money dried up and the momentum largely stalled. This would happen again in the late ‘80s, but new developments once again reenergized the world’s imagination and the train started moving again.

It seems there are just too many possibilities for the field of Artificial Intelligence to stay buried for long… especially in light of the technological revolution that has taken place in the first part of the 21st century. In a world of satellites and digitization and quantum physics and nanotechnology, we’re bound to explore the boundaries of computer capabilities.

Though we may not realize it, Artificial Intelligence does exist in today’s world in various forms. We encounter it in a number of ways, some of which we don’t even notice. But one of the most high‐profile displays of AI technology in recent memory actually turned up in a distinctly old‐world venue: the game of chess.

Beginning in 1989, Russian chess champion Garry Kasparov engaged in a series of matches against chess‐playing computers designed by IBM. Perhaps the most famous match took place in 1997, when Kasparov was defeated by a computer called Deep Blue in a controversial six‐game match. Kasparov would later avenge the loss in a series of rematches, but the lesson was clear: Deep Blue and the machines that followed in its footsteps clearly demonstrated an advanced capacity for creative and critical thought –something which many doubters had long claimed was impossible.

The years since Deep Blue’s emergence have brought other major developments in the field of Artificial Intelligence. To one degree or another, computers now have the ability to do everything from diagnosing serious medical conditions to composing original music(both pop and classical, in case you were wondering). More often than we realize, a branch of AI is responsible for the backbone of some new technology that quickly becomes a fixture in our everyday lives. Take a quick look at all the gadgets in your home. I’ll bet you can find at least a few that rely on AI, right?

Then there are the robots.

Ah yes, the robots. Every so often I will come across a news story that shows video of a robot designed by a brilliant team of scientists in some far‐away lab –Stanford and the Massachusetts Institute of Technology (MIT) have each made great strides here in the U.S., but there are many similar projects going on overseas, particularly in Asia –and I always shake my head in awe and admiration. These robots can follow commands but, so far, have trouble thinking on their own. That’s because no one has quite cracked the code for how to get them to process thoughts beyond the formal logic of, say, a Google search or a chess match. In those instances, a computer can sift through web sites or analyze probability based on previous chess moves, and it does it quite well. Far better than humans, in fact. But what computers still cannot do is connect that formal logic to abstract concepts, which is why, if a robot were to beat you in chess, it may be able to shake your hand afterward, but it would not be able to adjust if you wanted to high‐five instead –not without being programmed to do so –nor would it understand the reason or the meaning behind your gesture.

Of course this doesn’t mean that there is not a great deal of practical use for artificial intelligence today. Indeed, some form of AI is already being used for everything from building cars to programming your TV. And more importantly, there is nearly constant daily progress. When you stop and think about it, we’ve come an awfully long way in a very, very short amount of time. I wonder what tomorrow might bring.

Looking Ahead

It is true that many people fear what the future holds. (It’s also true that people fear robots who look too much like real people –it’s a lot like the way people fear clowns. Excuse me while I shiver away the goose bumps that suddenly appeared on my arms and neck.) Ever since John McCarthy and his peers first coined the phrase ‘Artificial Intelligence’ there have been those who oppose its development on the grounds that we, as humans, may be getting in over our heads. That we may one day create a computer that we will not be able to control. That we are destined to find ourselves the servants instead of the masters. And while it is impossible to say whether that eventuality comes to pass or not, what has become clear is that when it comes to Artificial Intelligence, the sky really is the limit. Which is why, when it came time for me to send 251 of the brightest teenagers from all over the world into space in order to save mankind, the person I put at the center of their experience wasn’t really a person at all.

The narrator of the Galahad series, and the one who maintains many of the ship’s vital functions, is a thinking, talking computer called Roc. Roc was designed in the image of his creator, Roy Orzini, but he also flashes a personality that is very much his own. He’s sarcastic and wise, and he has a sense of humor, too. He develops relationships with crew members that go beyond the formal, professional capacity that you’d expect. Triana Martell is the Council Leader of Galahad, and there’s no question that she is the star of the show. Other characters come and go, and I’ve found when I visit with fans of the book series, they each have their own favorite character.

But if those characters are the pieces that make up the Galahad series, then Roc is the glue that holds those pieces together. He’s responsible for so much of the technical aspects of their journey –everything from regulating the oxygen, to maintaining the radiation shield, to preventing a catastrophic collision with an asteroid –but he also uses his advanced powers of deduction on a personal level. He’s a confidant, a mentor, a friend. He’s a computer who fits the very definition of Artificial Intelligence, and then, when you least expect it, he is so much more.

Will science ever take that next leap in the development of computers? Might our children one day have a best friend who was designed and constructed in a warehouse somewhere? Or, as some claim, is there an essential part of the human experience that can never be replicated?

I don’t know the answers to those questions any more than you do, but I’ll tell you this: like just about everything else in the world of science, I can’t wait to find out.

    Dom Testa continues his powerful teen suspense science fiction space opera as a potential new danger greets the earth travelers

    When the tail of the comet Bhaktul passed through the Earth's atmosphere, it left behind toxic particles that caused a fatal disease for anyone over eighteen years old. To prevent human extinction as those turning eighteen caught the disease also, a bold plan to send 251 chosen teenagers led by Triana to fly a spacecraft the Galahad to the distant Eos solar system began (see The Comet's Curse).

    They deal with a stowaway, meet the Cassini aliens on a Jupiter moon (see The Web of Titan) and navigate though the hazardous Kuiper Belt (see The Cassini Code). Although the crew expects smooth sailing once they clear the Belt, they are met by strange vulture-shaped organisms. Unsure whether the entities are sentient and friendly, biological or mechanical the Council agrees to move ahead with the mission. Still they capture one of the essences leading to a series of mistakes as a crew member dies on board and another human makes a unilateral decision that impacts survivability on the Galahad.

    Dom Testa continues his powerful teen suspense science fiction space opera as a potential new danger greets the earth travelers. The teens have become increasingly cohesive though they come from a variety of cultures and nations as they deal with perilous adventures. They prove dedicated and responsible and need the success of their mission. The story line contains numerous subplots involving the personal needs of the crew, but also moves forward the overarching major theme of travel through unknown space in a terrific odyssey.
