An entertaining story with a pair of sword wielding, pistol shooting thirteen year olds. For some weird reason, I couldn't stop worrying about what Karl and Esther's families must have gone through when they discovered they were gone. Or how everyone was okay with the fact that Karl kept finding and "keeping" things that didn't belong to him. other than that, a really good story with interesting characters. If you're looking for a YA book filled with action packed scenes, look no further.
