My 14 yos are reading To Kill a Mockingbird and Red Badge of Courage. I love our school. No pc garbage. Even my son's liberal history teacher is great. She is really left (was at the Cindy S. march in Washington) but loves to have kids in class that actually know what is going on. She encourages debate and my son is thriving on that.
My daughter also read those books at age 14 (or younger). Keep a close eye on what they trot out next. It never ceases to amaze me.
