Disturbing Books ?

What would you name as the most disturbing books you've read..

For me it'd have to : Anything by Peter Sotos, De Sade, American Psycho by Bret Easton Ellis



 What about you ?

If De Sade was offensive purely for the sake of being offensive, then it was a bad move. Don't think in 21st century terms. De Sade spent several years in jails because of his books. Which doesn't mean that they are so great... but at least he wasn't just playing around.
