** spoiler alert ** 
 Something about this left me a little unsatisfied, although I'm not sure why. It wasn't because of the ending, which was very open-ended in a way I like. The world-building was very well done-- there was obviously a very complete history for this world, but it was never intrusive. Solidly built, lightly felt. I wanted to know more-- it was so complex a creation, there was so much more I wanted to explore.
