Woohoo! 
 First Audio Book Complete! 
 Wow, I drive ALOT. I drive, on average, around 1.5 hours a day. For such a small city, that's ridiculous. 
 I enjoyed listening to this book. I also really found it beneficial to hear how some words are pronounced, instead of creating my own pronunciations and making an ass of myself. 
 Once again, Westerfeld has created a very interesting system. Unfortunately, it was lost on me. I zoned out during most of the battle and device description scenes, which constituted 70% of the book. As impressive as the world Westerfeld created is, I feel it took away from the characters. Too much effort was spent focusing on machines, that the humans were secondary. 
 I'm still interested in the conclusion to this series, even with the juvenile characters.
