Charlotte It's of my opinion that anyone who wants to should read it. I read it around that age and I didn't find it at all graphically disturbing. But that's just me. It's really up to each individual person!
Phoebe I read it when I was 12, and it isn't that graphic with blood and gore. The movie, however, might be as it is rated M, but the book depends on how well you can handle it.
