When diplomacy and military intervention fails, the President of the United States calls upon them to solve America’s most dangerous crises. Brian Rhome thought his time within this elite group was over. But now he’s on a desperate race against time around the globe as he confronts the traumas of his past and unravels a deadly conspiracy that threatens the highest levels of American democracy.

After her young husband’s untimely death, Army veteran Cassie Gale decides to take a few days of solitude in the Alaska wilderness before she starts her new job. But when she fails to show up on her first day and her dog is discovered injured at her wrecked campsite, her father knows that this is much more than a camping trip gone awry. As it turns out, Cassie is not the first person to disappear without a trace in Alaska’s northern interior. But not all disappearances can be explained. Cassie’s is one of them, along with a number of other outdoor enthusiasts who have vanished in recent years. Regaining consciousness in a Russian prison, Cassie finds herself trapped in a system designed to ensure that no one ever escapes alive.
