The characters in this book were very developed. I grew to care about them, or hate them! I could not put this book down! It kept me guessing from the very beginning. Just when I thought I had it figured out something would happen and I'd think, Well, there goes that theory! So many twists and turns, several times I gasped out loud! That ending tho! I never saw it coming! The best kind of book is one that keeps you guessing and fools you in the end! Once you start this book, expect to get nothing else done. You will not be able to stop reading. When I woke up the next morning I had to reread the last chapter just to verify that I really read what I thought I'd read. I think that is the first time I've ever done that!
