Before I Go to Sleep by S.J. Watson

For Christine, going to sleep is the worst possible thing she can do. When she wakes up each morning, she has no idea what happened the day before--or the last twenty years, during which time she has had amnesia. She also wonders about the man she lives with, whom she discovers each day to be her husband, Ben. Even worse, she finds an entry in a journal that she's been keeping that says "DON'T TRUST BEN." It was Mr. Nash, Christine's doctor, that suggested she record what happens each day. Christine has been seeing him secretly and it seems she's making progress, remembering her past by re-reading her diary. But instead of helping her, it could become a nightmare.... A first novel that stays with the reader long after the story's over. It will be published next month.
