I love the originality of this book, attached of course to common themes for a sci-fantasy (the lost mother, the meaning of growing up, the Monsters that never die, etc.). But I'm not very happy about the ending, which requires an immediate move to Book Two, unlike a good trilogy which gives you a moment to breathe in each case. It's like the crappy non-ending of the Girl who Chases and Is Chased and Plays with Fire and Forgets Her Dad Has Surveillance Equipment Too. That cost the book a star, which it actually earned before having it taken away.
