I'll admit it.  I wanted to see the movie, Before I Go To Sleep, but just didn't get to it.  Thank goodness the book  remains available. This involved but uncomplicated tale wrapped me up and kept me until it was finished. Some books contain great characters, in some books the language paints scenes with graceful lines, and still other books offer unique and intricate plots. S. J. Watson's book gives us a unique plot with an interesting main character defect.

 Christine, the main character, is fully fleshed out, though the other characters are not. Some of this exists because the story is told by Christine, and, well, she can't remember. None of the people in her current life exist outside of today. Watson's excellent writing drives the reader deep into Christine's world, letting them experience Christine's emotions and her sense that all the people around her are somewhat wooden.
