Bestselling, award-winning futurist David Brin returns to globe-spanning, high concept SF with Existence.
Gerald Livingston is an orbital garbage collector. For a hundred years, people have been abandoning things in space, and someone has to clean it up. But there's something spinning a little bit higher than he expects, something that isn't on the decades' old orbital maps. An hour after he grabs it and brings it in, rumors fill Earth's infomesh about an "alien artifact."
Thrown into the maelstrom of worldwide shared experience, the Artifact is a game-changer. A message in a bottle; an alien capsule that wants to communicate. The world reacts as humans always do: with fear and hope and selfishness and love and violence. And insatiable curiosity.
“Take a world soaked in near-future strangeness and complexity... Add a beautiful alien artifact that turns out to be the spearpoint of a very dangerous, very ancient invasion... Hotwire with wisdom and wonder... Existence is as urgent and as relevant as anything by Stross or Doctorow, but with the cosmic vision of Bear or Benford. Brin is back.” Stephen Baxter, bestselling author of Ark and The Time Ships
“In Existence, David Brin takes on one of the fundamental themes in science fiction--and what is also one of the fundamental questions humanity faces in this century. Since Brin is both a great storyteller and one of the most imaginative writers around, Existence is not to be missed.” Vernor Vinge, bestselling author of Fire Upon the Deep and The Children of the Sky
“Existence is a book that makes you think deeply about both the future and life's most important issues. I found it fascinating and could not put it down.” Temple Grandin, author of Thinking in Pictures

The universe had two great halves.
A hemisphere of glittering stars surrounded Gerald on the right.
Blue-brown Earth took up the other side. Home, after this job was done. Cleaning the mess left by another generation.
Like a fetus in its sac, Gerald floated in a crystal shell, perched at the end of a long boom, some distance from the space station Endurance. Buffered from its throbbing pulse, this bubble was more space than station.
Here, he could focus on signals coming from a satellite hundreds of kilometers away. A long, narrow ribbon of whirling fiber, far overhead.
The bola. His lariat. His tool in an ongoing chore.
The bola is my arm.
The grabber is my hand.
Magnetic is the lever that I turn.
A planet is my fulcrum.
Most days, the little chant helped Gerald to focus on his job—that of a glorified garbageman. There are still people who envy me. Millions, down in that film of sea and cloud and shore.
Some would be looking up right now, as nightfall rushed faster than sound across teeming Sumatra. Twilight was the best time to glimpse this big old station. It made him feel connected with humanity every time Endurance crossed the terminator—whether dawn or dusk—knowing a few people still looked up.
Focus, Gerald. On the job.
Reaching out, extending his right arm fully along the line of his body, he tried again to adjust tension in that far-off, whirling cable, two thousand kilometers overhead, as if it were a languid extension of his own self.
And the cable replied. Feedback signals pulsed along Gerald’s neuro-sens suit … but they felt wrong.
My fault, Gerald realized. The orders he sent to the slender satellite were too rapid, too impatient. Nearby, little Hachi complained with a screech. The other occupant of this inflated chamber wasn’t happy.
“All right.” Gerald grimaced at the little figure, wearing its own neuro-sens outfit. “Don’t get your tail in a knot. I’ll fix it.”
Sometimes a monkey has more sense than a man.
Especially a man who looks so raggedy, Gerald thought. A chance glimpse of his reflection revealed how stained his elastic garment had become—from spilled drinks and maintenance fluids. His grizzled cheeks looked gaunt. Infested, even haunted, by bushy, unkempt eyebrows.
If I go home to Houston like this, the family won’t even let me in our house. Though, with all my accumulated flight pay …
Come on, focus!
Grimly, Gerald clicked down twice on his lower left premolar and three times on the right. His suit responded with another jolt of Slow Juice through a vein in his thigh. Coolness, a lassitude that should help clear thinking, spread through his body—
—and time seemed to crawl.
Feedback signals from the distant bola now had time to catch up. He felt more a part of the thirty kilometer strand, as it whirled ponderously in a higher orbit. Pulsing electric currents that throbbed up there were translated as a faint tingle down here, running from Gerald’s wrist, along his arm and shoulder, slanting across his back and then down to his left big toe, where they seemed to dig for leverage. When he pushed, the faraway cable-satellite responded, applying force against the planet’s magnetic field.
Tele-operation. In an era of ever more sophisticated artificial intelligence, some tasks still needed an old-fashioned human pilot. Even one who floated in a bubble, far below the real action.
Let’s increase the current a bit. To notch down our rate of turn. A tingle in his toe represented several hundred amps of electricity, spewing from one end of the whirling tether, increasing magnetic drag. The great cable rotated across the stars a bit slower.
Hachi—linked-in nearby—hooted querulously from his own web of support fibers. This was better, though the capuchin still needed convincing.
“Cut me some slack,” Gerald grumbled. “I know what I’m doing.”
The computer’s dynamical model agreed with Hachi, though. It still forecast no easy grab when the tether’s tip reached its brief rendezvous with … whatever piece of space junk lay in Gerald’s sights.
Another tooth-tap command, and night closed in around him more completely, simulating what he would see if he were up there, hundreds of klicks higher, at the tether’s speeding tip, where stars glittered more clearly. From that greater altitude, Earth seemed a much smaller disc, filling just a quarter of the sky.
Now, everything he heard, felt or saw came from the robotic cable. His lasso. A vine to swing upon, suspended from some distant constellation.
Once an ape … always an ape.
The tether became Gerald’s body. An electric tingle along his spine—a sleeting breeze—was the Van Allen radiation wind, caught in magnetic belts that made a lethal sizzle of the middle-orbit heights, from nine hundred kilometers all the way out to thirty thousand or so.
The Bermuda Triangle of outer space. No mere human could survive in that realm for more than an hour. The Apollo astronauts accumulated half of all their allotted radiation dosage during a few minutes sprinting across the belt, toward the relative calm and safety of the Moon. Expensive communications satellites suffered more damage just passing through those middle altitudes than they would in a decade, higher up in placid geosynchronous orbit.
Ever since that brief time of bold lunar missions—and the even-briefer Zheng He era—no astronaut had ventured beyond the radiation belt. Instead, they hunkered in safety, just above the atmosphere, while robots explored the solar system. This made Gerald the Far-Out Guy! With his bola for an arm, and the grabber for a hand, he reached beyond. Just a bit, into the maelstrom. No one else got as high.
Trawling for garbage.
“All right…,” he murmured. “Where are you…?”
Radar had the target pinpointed, about as well as machines could manage amid a crackling fog of charged particles. Position and trajectory kept jittering, evading a fix with slipperiness that seemed almost alive. Worse—though no one believed him—Gerald swore that orbits tended to shift in this creepy zone, by up to a few thousandths of a percent, translating into tens of meters. That could make a bola-snatch more artistic guesswork than physics. Computers still had lots to learn, before they took over this job from a couple of primates.
Hachi chirped excitedly.
“Yeah, I see it.” Gerald squinted, and optics at the tether-tip automatically magnified a glitter, just ahead. The target—probably some piece of space junk, left here by an earlier, wastrel generation. Part of an exploding Russian second stage, perhaps. Or a connector ring from an Apollo flight. Maybe one of those capsules filled with human ashes that used to get fired out here, willy-nilly, during the burial-in-space fad. Or else the remnants of some foolish weapon experiment. Space Command claimed to have all the garbage radar charted and imaged down to a dozen centimeters.
Gerald knew better.
Whatever this thing was, the time had come to bring it home before collision with other debris caused a cascade of secondary impacts—a runaway process that already forced weather and research satellites to be replaced or expensively armored.
Garbage collecting wasn’t exactly romantic. Then again, neither was Gerald. Far from the square-jawed, heroic image of a spaceman, he saw only a middle-aged disappointment, on the rare occasions that he looked in a mirror at all, a face lined from squinting in the sharp light of orbit, where sunrise came at you like a wall, every ninety minutes.
At least he was good at achieving a feat of imagination—that he really existed far above. That his true body spun out there, thousands of kilometers away.
The illusion felt perfect, at last. Gerald was the bola. Thirty kilometers of slender, conducting filament, whirling a slow turn every thirty minutes, or five times during each elongated orbit. At both ends of the pivoting tether were compact clusters of sensors (my eyes), cathode emitters (my muscles), and grabbers (my clutching hands), that felt more part of him, right now, than anything made of flesh. More real than the meaty parts he had been born with, now drifting in a cocoon far below, near the bulky, pitted space station. That distant human body seemed almost imaginary.
Like a hunter with his faithful dog, man and monkey grew silent during final approach, as if sound might spook the prey, glittering in their sights.
It’s got an odd shine, he thought, as telemetry showed the distance rapidly narrowing. Only a few kilometers now, till the complex dance of two orbits and the tether’s own, gyrating spin converged, like a fielder leaping to snatch a hurtling line drive. Like an acrobat, catching his partner in midair. After which …
… the bola’s natural spin would take over, clasping the seized piece of debris into its whirl, absorbing its old momentum and giving that property new values, new direction. Half a spin later, with this tether-tip at closest approach to Earth, the grabber would let go, hurling the debris backward, westward, and down to burn in the atmosphere.
The easy part. By then, Gerald would be sipping coffee in the station’s shielded crew lounge. Only now—
That’s no discarded second stage rocket, he pondered, studying the glimmer. It’s not a cargo faring, or shredded fuel tank, or urine-icicle, dumped by a manned mission. By now, Gerald knew how all kinds of normal junk reflected sunlight—from archaic launch vehicles and satellites to lost gloves and tools—each playing peekaboo tricks of shadow. But this thing …
Even the colors weren’t right. Too blue. Too many kinds of blue. And light levels remained so steady! As if the thing had no facets or flat surfaces. Hachi’s questioning hoot was low and worried. How can you make a firm grab, without knowing where the edges are?
As relative velocity ebbed toward zero, Gerald made adjustments by spewing electrons from cathode emitters at either cable end, creating torque against the planetary field, a trick for maneuvering without rockets or fuel. Ideal for a slow, patient job that had to be done on the cheap.
Now Hachi earned his keep. The little monkey stretched himself like a strand of spaghetti, smoothly taking over final corrections—his instincts honed by a million generations of swinging from jungle branches—while Gerald focused on the grab itself. There would be no second chance.
Slow and patient … except at the last, frenetic moment … when you wish you had something quicker to work with than magnetism. When you wish—
There it was, ahead. The Whatever.
Rushing toward rendezvous, the bola’s camera spied something glittery, vaguely oval in shape, gleaming with a pale blueness that pulsed like something eager.
Gerald’s hand was the grabber, turning a fielder’s mitt of splayed fingers, reaching as the object loomed suddenly.
Don’t flinch, he chided ancient intuitions while preparing to snatch whatever this hurtling thing might be.
Relax. It never hurts.
Only this time—in a strange and puzzling way—it did.
A MYRIAD PATHS OF ENTROPY
Does the universe hate us? How many pitfalls lie ahead, waiting to shred our conceited molecule-clusters back into unthinking dust? Shall we count them?
Men and women always felt besieged. By monsters prowling the darkness. By their oppressive rulers, or violent neighbors, or capricious gods. Yet, didn’t they most often blame themselves? Bad times were viewed as punishment, brought on by wrong behavior. By unwise belief.
Today, our means of self-destruction seem myriad. (Though Pandora’s Cornucopia will try to list them all!) We modern folk snort at the superstitions of our ancestors. We know they could never really wreck the world, but we can! Zeus or Moloch could not match the destructive power of a nuclear missile exchange, or a dusting of plague bacilli, or some ecological travesty, or ruinous mismanagement of the intricate aiconomy.
Oh, we’re mighty. But are we so different from our forebears?
Won’t our calamity (when it comes) also be blamed on some arrogant mistake? A flaw in judgment? Some obstinate belief? Culpa nostra. Won’t it be the same old plaint, echoing across the ruin of our hopes?
“We never deserved it all! Our shining towers and golden fields. Our overflowing libraries and full bellies. Our long lives and overindulged children. Our happiness. Whether by God’s will or our own hand, we always expected it would come to this.

I've always been a fan of David Brin, from Sun Diver and The Postman to Heaven's Reach, I've read them all. I even ordered this book months before it was released. I have to give this book a conditional 4 stars because I didn't like this universe as well as the uplift wars universe. This may be because I can see that parts of the future really might become what Brin has written about. Existence is formatted like the Uplift Trilogy in that it has several threads - some threads and characters I liked more than others. One of the characters I had a problem with was Prof. Nozone because I had to slow down my reading to understand his dialog. Prof. Brin has always been good at space opera and he hasn't disappointed here.
The good: a sense of atmosphere in a complex and engaging story, with a different & original take on first contact, as well as a fleshed out, plausible future, raising and addressing intriguing questions about technological immersion. The uncertainty of where the book was going was even better, and Mr. Brin does a great job of keeping the reader's attention. Occasionally, the immersion in different character perspectives worked marvelously. Why not five stars? While the reader gets to know several characters in detail, only two main characters (Tor Pavlov and Gerald Livingstone) get both full development and full resolution (with two more getting a somewhat more perfunctory wrap-up). The jump forward in time in Part 7 is jarring, disrupting the previously excellent pacing in a way that the book does not recover from. The last part feels rushed and episodic. Many of the previous stories and characters are either left dangling awkwardly, not to be resolved here (except as indirect throwaway references), or end up as pointless dead ends. Despite the quibbles, however, it was still one of my favorite reads of the year.
Brin takes several modern trends and carries them to a logical extention in the near future. Weaving the stories of several main characters, he portrays the myriad factions within society as well as the political factions and agendas. He does all of this within the framework of the backstory to his Uplift Series.
An exceptional read with multiple angles exploring the myriad of possibilities being thrown at us in our increasingly technologically driven society. Dr. Brin explores many of the points of views we see developing around us from the youth of our nation, really most of the world, connected electronically like we older generations never conceived to those in society doing their best to slow or stop science and go back to that mythical golden age, "before". True there are many personalities to follow, not always easy for many, and some of the section jumps are great and take a while to adjust to, but on the whole the book is filled with thought provoking insights into so many of the facets of our society, from the seeming increase in autism to the dramatic and seemingly irreconcilable political disconnect between groups in our own country. Well worth the read. Thought provoking. In general optimistic but also scary.
Almost didn't read this due to other reviews and that would have been a shame. Story weaves in the best social arguments and observations other authors have made and develops them a little further. Really shocked by the other reviews. What's not to love about summoning a smart-mob!
I've been a sci-fi and David Brin fan for a long time and I have to say this is his best effort and the best all around sci-fi novel ever, IMHO, with memorable characters and a believable story as part of the mix. Spanning decades starting in the not too distant future and connecting with several of Mr Brin's other novels, Existence should be a very rewarding read for fans and newcomers alike.
Appreciated the focus on the many risks to species survival beyond earth. The emphasis on sublight travel created a number of opportunities for a good story. But I felt that the author failed to capitalize on character development. I also disliked the story's jumping ahead many years and answering the questions / past conflicts in passing. It is a creative work but lacking in key elements to make a great novel.
I love theoretically possible tech. We need much more Science Fiction like this to inspire and take us where need to be going, for the reasons explored within these pages. I love how Brin visits many of the big questions of existence.
good story , very well written and will hold your attention the whole 900 pages. the story is about our search for OTHERS in our immense galaxy.We are so scared of being alone and yet afraid of finding smarter more aggressive races. when we do find evidence of OTHERS and they can still talk to us, because of their amazing new tecnology. we almost become trapped in their mistake and we learn to call them virus instead of savior. we grow up as humans and take control of our own destiny.
