Tom's life is not what it once was. His marriage is on the rocks and his writing career has stalled. Then his best friend, Neil, returns from teaching neurology in California. But all is not what it seems--Neil has been working for the U.S. government cracking the minds of suspected terrorists and has disappeared, leaving behind evidence that he has been employing his unique skills on civilians. And it's only when Neil gets closer to his ultimate target--Tom--that the full horror of his plan is revealed.
