The mission seems simple enough: extract a pharmaceutical magnate from Russian soil. But nothing is as it appears to be. A desperate call thrusts Captain Tucker Wayne and his stalwart military dog, Kane into a frantic race to rescue the brilliant-but-deluded Abram Bukolov from a cadre of skilled assassins. Hunted and betrayed at every turn, Tucker and Kane must discover the truth behind a horror out of the ancient past that can be weaponized to terrorize the modern world. As time rapidly runs out, the deep and intimate bond between dog and soldier will be tested to the extreme. It will take all of their skill, talent, and, most of all, trust in each other to piece together a mystery going back to the origins of life on Earth, to discover the key to an ancient peril that can destroy the heartland of America, and, with it, the world.
