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.

kefka is the evil prince of darkness in ff6.  you're thinking of kAfka.

I guess everyone was right when they said I was missing out...

Kafka is a shitty author. I tried to read a compilation one time, but I couldn't; it was just too goddamn shitty.

Give ^House of Leaves a miss IMO. Most of it went over my head. The main story about Navidson was a little fun but the annotations and side story was a waste of space.
