Callsign: King - The Brainstorm Trilogy is a complete collection of three novellas featuring Jack Sigler, aka, King, the lead hero in Jeremy Robinson's Chess Team. The collection is 144,000 words, far longer than any of the Jack Sigler novels and jam-packed with cool science, high-octane action and strange creatures. The trilogy is $4.00 less than buying each novella separately.



The fabled Elephant Graveyard has been discovered. It contains enough ivory to make Ethiopia a wealthy nation. But the cave contains more than physical riches—it also holds the means to control the world. Fifteen scientists enter the cave. Only one leaves.

Jack Sigler, Callsign: King (field leader of the covert, black ops Chess Team) receives a cryptic text from Sara Fogg, his girlfriend and CDC ‘disease detective’. A catastrophic disease has been reported in Ethiopia’s Great Rift Valley, but Fogg suspects something more is going on. Her suspicion is confirmed when King’s arrival in Africa is met by a high speed assassination attempt.

As King fights against two competing, high-tech mercenary forces, each struggling for control of the deadly discovery, Fogg disappears. Working with the surviving member of the science team that made the discovery, King begins a search for Fogg and the source of the potential plague that takes him back to the Great Rift Valley, back to the Elephant Graveyard, and brings him face-to-face with modern man’s origins.


Strange things have always happened in the Superstition Mountains of Arizona… Bizarre lights, reports of cave entrances that appear and then vanish, hundreds of mysterious disappearances…and rumors of monstrous creatures that inhabit a labyrinthine underworld.

When a terrifying accident on an Arizona highway leads to a military exclusion zone and a cover-up of staggering proportions, Jack Sigler—Callsign: King, field leader of the elite and ultra-secret covert Chess Team—joined by his closest friend, archaeologist George Pierce, sets out into the desert, intent on discovering the truth.

Assisted by a beautiful paranormal investigator, dogged by soldiers intent on preserving the quarantine, and pursued by a relentless legendary hitman, King soon finds himself in a race against time to prevent all out war with the creatures that inhabit the underworld.


Twice before, Jack Sigler—Callsign: King—has stopped the mysterious ‘Brainstorm’ from destroying all life on earth. Twice before, he’s survived Brainstorm’s assassins. So when the mastermind behind Brainstorm surfaces in Paris, King goes on the offensive.

As the final showdown unfolds in the legendary City of Lights, the villain’s scheme to plunge the world into literal darkness is revealed. But even Brainstorm isn't ready for the destructive force that has been unleashed…an entity of darkness imprisoned for more than a thousand years, set free now to devour...everything.

The blackout has begun… When the sun rises, the world will end.


“Rocket-boosted action, brilliant speculation, and the recreation of a horror out of the mythologic past, all seamlessly blend into a rollercoaster ride of suspense and adventure.” —James Rollins, New York Times bestselling author THE DEVIL COLONY

“With THRESHOLD Jeremy Robinson goes pedal to the metal into very dark territory. Fast-paced, action-packed and wonderfully creepy! Highly recommended!”
—Jonathan Maberry, New York Times bestselling author of ROT & RUIN

“Jeremy Robinson is the next James Rollins”
—Chris Kuzneski, New York Times bestselling author of THE SECRET CROWN

“If you like thrillers original, unpredictable and chock-full of action, you are going to love Jeremy Robinson...”
—Stephen Coonts, New York Times bestselling author of DEEP BLACK: ARCTIC GOLD

I throughly enjoyed The Brainstorm Trilogy, it was my introduction to the writing of Jeremy Robinson and since reading it, I have read many more. I think the writing partnership of Sean Ellis and Jeremy Robinson is genius. They both know exactly what works and how to get a reaction from the reader. After reading this trilogy you will be crying out for more. Jack Sigler, Callsign: King sure knows how to get himself into and out of trouble. Just give it a try.

Call Sign: King - Brainstorm is a side story of Chess Team Commander, Jack Sigler. This is a 3 part Novella series makes up the book. For fans of the other Chess Team novels who love Jeremy's fast paced, smart, action packed thrillers. King is joined by his girlfriend and CDC detective Sara Fogg, and his best friend archeologist George Peirce (who was in the Pulse novel).

Callsign: King - The Brainstorm Trilogy by Jeremy Robinson was an action packed way to get to know Jack Sigler and his "family" better. This latest threat "Brainstorm" really gives King a run for his money, but the best is definitely left for the end... Exciting read!

Featuring King, a heart throb hero that you will love.  The Brainstorm Trilogy is all three King novellas in one. These are fun, interesting, and engaging short stories. King is part of an elite force called Chess Team. They fight to save humanity from madmen, myths, monsters, and many other hazards planning to wipe out the human race. In this series of shorts King is up against an opponent named Brainstorm.  The first story takes us to Ethiopia. King heads there after his girlfriend sends him a coded message. The Elephant Graveyard has been discovered and an infection released. Brainstorm is behind this, trying to find a way to control humans.  The second story takes place in Arizona. Making an appearance is the Mogollon Monster. Brainstorm has a scientist hidden at Superstition Mountain working to develop a new source of unlimited energy. King has a Soviet assassin on his heals all through the story, as well as the military who are protecting the research project.  In the third story we get to go to the City of Lights, Paris. King get sent there to acquire Brainstorm, who has arranged a party on the river during an energy conference. Again Brainstorm is trying to get control of the world’s energy. Unbeknown to King, the Soviets have also sent a team to retrieve Brainstorm. Also, Sara and Fiona, King’s adopted daughter, come to Paris. While touring the Louvre, they are drawn into scheme that produces a black hole and destroys the museum.  Through all the stories King is consistent in his convictions. He is a strong character that you are sure to like. There is a lot of science in these books. If you enjoy reading James Rollins then the Chess Team series and the Brainstorm Trilogy are for you.

The Chess Team books are a blast to read and I loved each of the Callsign books.  Get to know each character a little better with a great story.  You can't go wrong with Jeremy Robinson's books, check them out!

SF, mythology, action, military, this one has it all. Three action thrilling adventures as Jack Sigler (Callsign:King) goes against black holes, underground creatures and super computer that wants to rule the world. One recommendation read Pulse, Instinct, and Threshold first. You won't be sorry.

From the cookie cutter characters to the ridiculous plots and long loving descriptions of weaponry, this was a total waste.
