From the Wall Street Journal bestselling coauthor of the Tier One series comes a page-turning sci-fi thriller about the ultimate battlefield: the human mind. Deep in the Afghan mountains, Sergeant Michael Pitcher discovers an object with powers that defy explanation. After interacting with it, he suffers a traumatic seizure and is flown home for evaluation. Cleared by the doctors, Michael goes home to his relieved wife, Josie. But he’s a changed man. The once-loving husband is now coldly withdrawn. After emptying the couple’s bank account, he disappears into the night. When a team of scientists connected to Sergeant Pitcher vanishes without a trace, CIA agent Dean Ninemeyer comes to him for insight—only to find that the recovering soldier has also disappeared. Dean and Josie must now join forces in a desperate race against time, searching for answers in an ever-twisting mystery. What they uncover is a chilling conspiracy that already has the fate of the world in its grip.
