"In Robinson's latest action fest, Jack Sigler, King of the Chess Team--a Delta Forces unit whose gonzo members take the names of chess pieces--tackles his most harrowing mission yet.Threshold elevates Robinson to the highest tier of over-the-top action authors and it delivers beyond the expectations even of his fans. The next Chess Team adventure cannot come fast enough."
-- Booklist - Starred Review

"In Robinson's wildly inventive third Chess Team adventure (after Instinct), the U.S. president, Tom Duncan, joins the team in mortal combat against an unlikely but irresistible gang of enemies, including "regenerating capybara, Hydras, Neanderthals, [and] giant rock monsters." ...Video game on a page? Absolutely. Fast, furious unabashed fun? You bet."
--Publishers Weekly

Relentlessly gripping from start to finish, don’t turn your back on this book!”

--Jonathan Maberry, New York Times bestselling author of The King of Plagues  and Rot & Ruin

“Threshold is a blisteringly original tale that blends the thriller and horror genres in a smooth and satisfying hybrid mix.  With his new entry in the Jack Sigler series, Jeremy Robinson plants his feet firmly on territory blazed by David Morrell and James Rollins.  The perfect blend of mysticism and monsters, both human and otherwise, make Threshold as groundbreaking as it is riveting.”

-- Dead Robot Society

"THRESHOLD is absolutely grippin. A truly unique story mixed in with creatures and legendary figures of mythology, technology and more fast-paced action than a Jerry Bruckheimer movie.If you want fast-paced: you got it. If you want action: you got it. If you want mystery: you got it, and if you want intrigue, well, you get the idea. In short, I $@#!$% loved this one."

When a death in the family pulls King away, and the rest of the team is sent on a mission, Fort Bragg is attacked by a strange and overwhelming force. When the dust settles, Fiona is gone.

But the attack is part of a larger offensive. Around the world the last speakers of ancient languages are being systematically exterminated. As they fight to find the mastermind behind the killings, and Fiona, the team is hunted by strange creatures that defy explanation—living statues, genetically modified monsters and walking megaliths—sent by an enemy from their past. If not stopped, he will be able to remake himself, and the world.

Calling on help from old friends and ancient heroes, the team fights their most desperate battle yet, not just to save the world as we know it, but to rescue a little girl who wants nothing more than to call King Dad.

An ancient tower holds the key to unlocking a horrifying secret hidden within mankind’s most antiquated languages. If unlocked, the world as we know it will cease to exist.

Jeremy Robinson’s third book in the Jack Sigler series is a rocket-powered thriller, combining high adrenaline action, smart science, ancient legends, and stunning locations.
