It's a pretty good book, my only complaint is that there's really no ending. The cliffhanger in the end is so abrupt and, well, present. I understand the idea of a cliffhanger; the other wants to make sure that you will continue reading. But in this case, nothing is truly concluded. But for the most part, it's a good book. My 13-year-old son enjoyed it a lot, but even he was not thrilled with the lack of vending. Boo.
