I really enjoyed this book. The world building is excellent and I was interested in the story and characters right from the prologue onwards. The ending didn't surprise me (I predicted several key elements from about halfway through the novel) but was still very satisfying to read. 

My only complaint really was that the multiple point of view structure, combined with sometimes very short chapters, made it a little bit of a struggle to keep my concentration - especially as I was already leaning close to a reading slump when I started the book. To be fair though that's personal preference and I know some people really like that aspect of the novel.
