Before I Go To Sleep by SJ Watson

Every morning Christine wakes up and does not have any recent memories.  She awakes next to an unknown man who explains that he is her husband Ben.  He shows her a photo album to remind her of their lives together and tells her that she was involved in a hit and run car accident 20 years ago.   

After Ben has gone to work she receives a phone call from Dr Nash who tells her they are working together to try to help restore her memory and to look in the shoe box in the bottom of her wardrobe and read the journal she has started to write.  The journal tells her what has been happening over the last few weeks.  Slowly bits of memories pop into Christine’s mind.  She remembers that she was attacked in a hotel room and that she and Ben had a son.  Why is Ben not always telling her the truth?  Could it be that it is just easier for him to not tell her the whole truth every day as it is painful to keep on reliving it and grieving again and again?
