Aided by his brother Robert Puller, an Air Force major, and Veronica Knox, who works for a shadowy U.S. intelligence organization, Puller begins a journey that will take him into his own past, to find the truth about his mother.
Paul Rogers' time is running out. With the clock ticking, he begins his own journey, one that will take him across the country to the place where all his troubles began: a mysterious building on the grounds of Fort Monroe. There, thirty years ago, the man Rogers had once been vanished too, and was replaced with a monster. And now the monster wants revenge. And the only person standing in his way is John Puller.
