I'm not sure that 9-12 is the appropriate age group for this one. Sex with older men is mentioned and talked about several times, once in an incestuous way.
This is a strange book and not at all what I expected. It's about obsession and how it can lead your life into the wrong places, places you don't necessarily want to go. This was a little too far out there for me, and generally I'm not discouraged about subjects like this.
