I'm conflicted about this book. The dialogue is funny, fast and Whedon-esque (in fact, a LOT of this book could have been modeled on Firefly. A disturbing amount, as I think about it) and the characters are likable enough- but there's inadequate world-building. I didn't get enough of the backstory to believe, and I didn't get enough insight into the characters to really care deeply. The flow of the plot was choppy and difficult to follow, though action-packed and exciting.
