Before I Go To Sleep/S.J. Watson/360 pgs.

If you like psychological thrillers, this is the book for you! Christine Lucas lost her memory years ago as a result of an accident. During her waking hours, she remembers certain events, only to lose them again when she falls asleep at night. Christine's therapist encourages her to record her memories in a journal during the day, so that she can review them the next day. As Christine recalls more events, she doesn't know who to believe or trust. It's a very riveting debut.
