This was a lot of fun. The tone and characters reminded me of Jeff Smith's Bone series
, and the setup for an ongoing ensemble of characters was great to set this up as its own series. Pearl devoured it before I got a chance to read it, and she loved it. Science fiction, main character is a girl, she rescues a boy--great package for sci-fi! My favorite scene was when she got to really go all out with the stomping boots.
