Cold Harbor

"After a period of brutal isolation in a CIA black-site prison, former Marine and gifted hacker Gibson Vaughn is free--but with no idea where he was or how much time he's lost. Struggling to maintain his grip on reality, he races to return to the life he left behind. Angry and disoriented, his thoughts turn to vengeance and the man responsible for his rendition. But Gibson's drive for retribution and the ghosts of his violent past plunge him back into a world he wants only to escape"--Amazon.com.
