When I was in Junior High, we read "The Scarlet Letter". That has some pretty "adult" themes in it. We also read "The Great Gatsby", which IIRC, included themes such as bootlegging, adultery, murder, and abortion(?). Hemingway's "Hills Like White Elephants" is about abortion for sure (as well as probably statutory rape).
When I was 12 or 13, I read the entire "Flowers in the Attic" series - checked it out at the public library and read them. Those have rape, incest, and murder, and I don't want to have sex with my sisters because of it.
However, you know your child, and if you feel he's not mature enough for this book, have him do the alternate activity. But if I were in your place, I would read the book BEFORE making the decision.
