I think Chuck Palaniuk is pretty clever. I've read a few of his books, Survivor, (which is incredible) and Choke (lesser so).
I absolutely loved Survivor- although it may not be everyone's cup of tea. It's straightforward, inane, incredibly cynical, original... narcissistic... an increidbly twisted sense of humor if you're into that.
The only problem is, his books are all basically about the same thing, have the same formula. Survivor though, is my personal favorite. It's all so wonderfully ridiculous.
He reminds me of Bret Easton Ellis - similar narrative style, and all his books are pretty much the same and have the same moral/point. I mean, all of Ellis' work is about society's greed and commercialism and its affect on the soul. American Psycho is interchangeable with Rules of Attraction which is interchangeable with Less Than Zero.
Palahniuk is very similar.
