What if every day, when you woke up, you had forgotten the last several years of your life? How would you piece your "now" together? Would you trust the people who share your daily life? This is the basis for Before I Go To Sleep by S. J. Watson. As Christine, the main character, starts piecing things together, some things fit and others don't. Soon, the more she uncovers, the less sense everything makes. I flew through this book. The more I found out about her life, past and present, the harder the book was to put down. At a certain point, once some major surprises are revealed, I bet you won't be able to put this down either!
Without her husband's knowledge, Christine, whose memory is damaged by a long-ago accident, is treated by a neurologist who helps her to remember her former self through journal entries until inconsistencies begin to emerge, raising disturbing questions.
