ON THE BRINK OF NUCLEAR WAR, A FORMER SOLDIER RESPONDS THE ONLY WAY HE KNOWS HOW—SEND THE BAD GUYS STRAIGHT TO HELL. As a Special Forces veteran with extensive weapons and hand-to-hand combat training, Chris Harding developed a reputation as a cold-hearted killer. But this lethal status came with a price—severe PTSD that robbed him of both his family and career. If only he could get back on the battlefield where he belongs. He gets his chance when the United States learns that Russia has built a quantum computer capable of launching nuclear missiles in a fraction of a second. And they plan to use it. Chris is recruited by a private military contractor to join a top-secret CIA mission to disarm the computer and every nuclear bomb in Russia. Failure means the start of a war where no one wins. Joined by a band of unlikely heroes and armed with little more than bravery and patriotism, Chris discovers that they've been betrayed by one of their own. They are thrust into an international conspiracy that runs deeper than they could ever have imagined and confronted with the stark reality that no one can be trusted—not even themselves.
