I really struggled to figure out why I didn't like this book. The characters are funny, the violence is violent, the threat is significant. And then about 75% into the book I realized I didn't like it because it feels like nothing matters. The characters don't care about saving the world, they don't care about their own lives -- they aren't fighting for or against anything, they're just fighting because it's what they do. The lack of intention makes it really hard to care what happens to the characters or the world.
