By far, the most enjoyable book of the series. I had some difficulty trying to figure out if I liked the first book since it focused so much on the angsty teen crap. This one left all of that behind and zeroed in on going on weird adventures. I have no idea how Grossman thinks up this stuff. He has a fantastic imagination. I hope that there is some sort of follw-up to this, whether it is another book (or trilogy) or movie.
