Wow.
I mean wow. This series is just so good. The first book (this one) is a little slower and harder to get into than the rest, but it is only because Dinniman is building the world that Carl et al go on to explore.
Fantastic premise (original is many ways as well) and fun characters that get more and more depth as the series continues. Also, the company that did the recording (Soundbooth?) made is so fun to listen to as it has so many sound effects in the book.
B-B-B-B-Boss battle baby!
