Books that will fuck you up

I need a list of some.
I've heard about House of Leaves, but haven't got around to it.
I've also been mentioned the works of Kefka, but I dunno about that.
Some of Lovecraft's stuff is good, and I heard Solaris is a crazy book. So help me out guys, I need some twisted books.

You HAVE to read Harry Potter. All the kids get shitcrocked on butterbeer and take the squirting shits into a bubbling cauldron. Hagrid then spins a bottle of firewhiskey and immediately rapes whom it points to, then rapes Hermoine for no reason. While knuckles deep in Ginny's doodoo brown, Ron Weasly eats kitty minge for giggles.
