This is one of my favorites of 2013. It would make a great book club selection, as it brings up interesting questions when you finish. It is sort of like time travel with a twist. The main character relives her life over and over again, each time changing things based on subconscious memories. She is born in 1910 and after countless lives she understands the evil of WW2 before it happens and tries to stop it (which you see in the prologue).
It's a great book that I highly recommend!
