My brain hurts. No...really...it does! This whole series had me spinning, thinking, feeling, guessing , speculating, being certain, changing my mind, and guessing again. And I mean that in the best possible way. 
 This is the kind of book that's very hard to review. There's way too much that I can't tell you and way too much that I can't begin to figure out how to tell you. The characters are fantastic and the tension that you feel throughout is intense. The storyline moves forward, stalls, and sometimes moves back before you continue on. To be honest, you never know what you'll get when you turn the page. And, although that's a good thing, it can leave you reeling. I can tell you that this book does feel repetitive at times because previous scenes are brought back in order to provide additional information. That may not be everyone's cup of tea as the reader begins to feel a large amount of deja vu. For the most part I didn't mind it but I know that it can add to the confusion or frustration for some. 
 If I had to pick one way to sum up this book (and this series), it would be to warn you to expect the unexpected. Some of the twists and turn will surprise you and leave you staring at the page in disbelief, others will confirm your theories, and still others will add to the cocktail of confusion you've come to expect from these books. You may not always follow the train of thought...but you'll always want to. If you're up for a series that will make you think...if you're ready for a good mindf*ck, then these are the books for you. Get ready though because once you get started, it'll have you hooked until the end.
