“Before I go to sleep” reminded me a lot of Gone Girl with all of its twists and turns. I think I read it in two sittings because I absolutely couldn’t wait to find out what happened next. Jeff kept coming in and saying “still reading?!” – I was on a tear!
A la 50 First Dates (but a LOT more sinister), Before I go to sleep is about a woman with amnesia who forgets who she is every night as she sleeps. The next day she has to piece together her existence except she doesn’t know who to trust. It is CRAZY.
Go read it now, but make sure you have time in case you can’t stop!!
