It took me a few days to read the first part of this book and a few hours for the second. I couldn't put it down! You know how in a thriller-mystery novel when you find out the bad guy's motivation and it's kind of a let down every time because it was so much more in your mind? This was probably the first book that I did NOT feel that at the end. It was so good! I would highly recommend this book for high school students due to some language.
