This was a really great book that will keep you on the edge of your seat all the way through. This book is broken up into three parts and it does take a little bit to get through the book, but it doesn't feel all that long because you just can not wait to see what happens next! Then when you think you got some of the story figured out it throws you for a loop and you realize you were wrong the whole time but that just keeps in fun and interesting. I thought all the characters were fully formed and the authors did a wonderful job of building suspense by only giving away a little at a time. I also really liked the writing style of this book and I also thought the story flowed really well. I think this is a must read!
