I had a lot of questions and I'm not sure if I am missing something, or if this is just how this series of books operates (since I seem to remember feeling this way after a couple of the other books as well). We get little snatches of information but it's so little, unexplained, or glossed over, we never understand anything of depth about the motivations of the antagonists or their place in the world, despite getting at least 30% of the book from their viewpoint. So that brought it down a good bit.
I liked Lucy and Liao's sibling relationship, and the glimpses we see of their relationship to Liao's mother/Lucy's stepmother. The storytelling was much easier to follow when we were in Lucy's POV, and I wish we could could have kept that ease throughout the book, while still getting some aspects of the roaming world and the antagonists, but without feeling left in the dark.
I will be coming back for more, because apparently I can't help myself and I am SO curious if I will ever get a good idea of the world and the shadowy side characters and get answers to my many many questions.
