I have no idea what I expected, and in that, this one delivered
This is a book I enjoyed, and I would recommend with a word of caution I think. It is totally different. Like nothing I have ever read before... much like the first time you read one of Neil Gaiman's books, or even Tom Robbins... your perception of reality needs to shift by a few degrees to wrap your mind around what you are being presented with.
Especially after the Promise, I enjoyed this book. This is an intelligent read that pushes a few boundaries. Before reading it, I would like go read a few reviews and how folks respond to see whether or not it would be your cup of tea. Some moments are brutal, it isn't for the faint hearted, and yet it does present a character arc that makes sense, and a satisfying resolution.
