This book is amazing.
Sex: A lot of references. I think that CSM basically got everything except that it should also be noted that , near the end of the book, there is a picture of bare breasts.
Violence: When it comes to books, violence doesn't really bother me but, if your really picky about that sort of thing, check the CSM review.
Language: Language, too, really doesn't bother me. It's just words. At the same time however, there is a lot so I've given it an iffy rating even though I personally don't really mind.
Review: I read this book when I was twelve and it didn't phase me. Now that I look at this list, however, I feel like I ought to put the same rating as CSM but the thing is that I wasn't bothered and I don't really believe that books (or other forms of media) can really affect people's lives. When I read this, it didn't really seem all that bad to me and I doubt that it will traumatize today's kids.
