Differently-Written Books

I'm looking for more to read. I've got Douglass Adams' books, Flowers for Algernon, A Clockwork Orange and American Psycho under my belt, and I'm currently reading
Lolita
Beloved
Catch-22.

       On an off-note, I brought this up to someone IRL and they reccomended Slaughterhouse 5 to me, saying it was a great read. I found Slaughterhouse 5 to be terribbly overrated. Anyone have anymore?

Check out some Harlan Ellison short stories and some J.D. Salinger short stories.  They are both stylists of a high, high order.  Deathbird Stories, by Ellison.  Nine Stories, by Salinger.  Mind you, they're very different writers.  Ellison has this balls-out swaggering dangerous intellect, whereas Salinger surprises you by quietly turning his narratives inside out, and fucking with all of your expectations as a reader.  Everything tale in Nine Stories is a damn mind-bender.
