This one borders the 2/3 stars for me. I liked parts, but overall, most of these people are seriously messed up, and they get away with way too much. For it to be a really satisfying book, Gray would have had to do a lot more groveling. What about his sister? I don't want to be too spoilery, but that girl has some problems and I did not buy her ending. Lots of self-destructive people gravitating towards each other. 
 ETA: The more I think about this book, the more I dislike it.
