virginia andrews "flowers in the attic" which was available from my private, catholic, all girls school library!
LOL Flowers in the Attic was hot property at my all-girls Anglican private school - you had to be on the waiting list (I bet no one at the school ever read it). Tweens will always want slightly racy stuff. As for the violence part, I've not read the books but it sounds pretty mild. IMO a girl will grow up to think violence against women is ok she sees her dad beat up her mum, not if she reads about a rough kiss in a fantasy novel. I bet every girl who read flowers in the attic didn't race out thinking it was ok to sleep with her brother.

Although I wouldnt support banning I also wouldn't go and recommend it to a pre-teen. Just my opinion.
This is the crux of it though - aren't they talking about not having it at a primary school library? I would say I'd support that, because 12 year olds might be up for it but I don't personally think 10 year olds should be reading about fictionalised sex (unless we are talking about a 10 year old who has been abused and her therapist has recommended that she read a particular fictional book which might help her deal with what had happened to her). Personally I am pretty repulsed by the overt sexualisation of young girls - sure 10 year olds are sexual creatures - all humans are - but I see pre-teens reading Twighligh just part of the same continum which sees 6 year olds wearing mini-bras and high heels. My stepbrother's wife is looking for a g-string for her 8 year old - that is just wrong IMO....
