I just bought the Heroin Diaries by Nikki Sixx thinking it would be a great resource for health class book reports. I had no idea it was so graphic but I hate to take it off the shelves because it's so good. My temporary solution has been permission slips but I don't want to have permission slips for every questionable book. I also recently bought the Girl with the Dragon Tattoo but I've just been warning kids that it has a violent rape scene in it and if their parents wouldn't approve of them reading it they shouldn't check it out. This probably wouldn't be such a problem in a larger city but I live in a tiny super-conservative town. Any ideas?
