The last thing I remember - Andrew Klavan

The first book in an exciting new series reminiscent of The Bourne Identity and 24

Charlie West studies hard, stays focused and has just gotten the phone number of the prettiest girl in his class. He is thinking about joining the air force after graduation. He is a third degree black belt. He never gets in trouble. Until now. Charlie has woken up in a nightmare. He's strapped to a steel chair, and someone outside the door just ordered his death. . .

Even worse - he can't remember a thing about how he got here.

By calling on his deepest reserves of strength and focus, Charlie manages a desperate escape. . . but his nightmare isn't ending. There's a whole year of his life that he can't remember. A year in which he was convicted of murdering his best friend and working with terrorists. Charlie knows that can't be true. But what is? Staying alive long enough to figure out the answers may be the least of his worries. . .
