Uhhh, what?!?! My brain has almost no clue about what it read.. seriously! That was a bit of a mind-bender. I still am not totally sure about what was the truth and what was really going on. I wish a bit more of that got explained. And I had so many theories running through my head the whole time! This book really makes you think and keeps you guessing until the end.
My only real problem with this is that, while you're guessing about what's going to happen, everything that happens is never really a clue. A+B does not equal C in the end. So don't even bother. Even though this book is over 400 pages long, I wanted more. In the end, I craved more explanation about all that WTFery and all the stuff Alice learns about Rachel along the way. This book was just crazy, but I really liked it!!
