This is a YA book and, whilst the subject matter is quite sensitive, the author has handled it thoughtfully and appropriately for that age range. As a parent I do not censor books; as a teacher I obviously have to be a little more circumspect - this text is one that I have in my personal tutor library for a Y9 group. I'd say it is ok for a 13 year old - it is certainly handled a lot more sensitively than I've seen the topic handled online, where it is easily accessed.
