A good, fast-paced thriller, I really enjoyed reading this book, even with the ending just leaving you wanting more; I am really curious to see where this is going. I feel the characters are well developed and that most teens will be able to relate to at least some aspect of their personalities and motives. It read a bit like a movie, but for teens I do not see that as a problem at all. I know I am going to read the next book and will not hesitate to recommend it.
