Our memories are what make us who we are. Imagine waking up in the morning and having absolutely no memory of your life. Now imagine doing that every day, for years. This is the situation for Christine, who has a rare form of amnesia. Each day is a blank slate. A first novel from British author S. J. Watson, I found this to be an exciting and haunting story. There are a few terms that give it a British flavor, but it could easily take place anywhere. The main character is someone you care about from page one, as she shares her life, one day at a time. Her doctor suggests she begin to keep a journal to help remember what she learned the day before. Flashes of her past begin to surface that do not seem to fit with her present life. Right along with her, you are drawn into a psychological thriller almost without knowing it. The pace picks up for a whirlwind ride and what seems a positive outcome for all concerned. Or is it? This is a one-sitting book: don't start it late at night!
