Before I Go to Sleep, by S.J. Watson

What if you woke up every morning, thinking you were twenty-five, and then looked in the mirror and saw a forty-something?  What if you discovered you were in bed with a man every morning that you didn't know, in a room that was unfamiliar?  This is the life of Christine, a writer, who suffers from amnesia.  Christine cannot retain memories after she falls asleep at night.  In the morning, she wakes to thinking she is twenty-five, with her entire life ahead of her.  Every morning, her husband, Ben, tells her who she is, and who he is, and then leaves for work for the day.  Christine is left alone in a house she doesn't know.  Then at the same time every morning, a cell phone rings, and a Dr. Nash tells her to go to her closet, in the shoebox, and read her journal.  She reads about what she's done previously, with no memory of the events.

Then one day, after appointments with Dr. Nash that Ben doesn't know about, she goes to find her journal without being told to.  Bits and pieces of her memory begin to return, but they do not correlate with what Ben has told her of their lives together.  She remembers a son, but Ben told her they had no children.  Christine remembers Claire, her best friend from college, but Ben tells her she's moved away.  Bit by bit, with Dr. Nash's help, Christine begins to remember more and more, but what remembers isn't what it seems.

Watson was a new author for me, and this book was chosen for my book club with fellow reviewer Lindsey.  You really get into the mind of Christine and her daily struggles to remember her life.  The last 100 pages or so are so full of new revelations and action, that I could not stop reading- even if the house were on fire!  The twists in the plot are so subtle, you don't realize what's going on until Christine does.  A nail-biting story that will leave you feeling a bit unsettled.
