I wish I would have read this book in bigger chunks than 1/2 hour break times and bits here and there. This is definitely a book you need to read in just a few sittings or it might get a little too confusing. Also, it'll go fast that way, because it was pretty slow going for me, but the last few chapters totally made up for that. I'd like to thank Donnie Darko for preparing my mind for the idea of universes that come into existence just because someone/something from the original universe or fixed timeline has entered into it, and that the possibility our current existence is only a shadow of the original timeline and we could all blink out at any second and never know it. On that happy thought, you should totally read this book! :)
