Daphna,
I bet you'd like Asylum, by Patrick McGrath. A very beautifully written goth novel. Irving is (was) great, until A widow for one Year, which pulled at my guts for three months!
I usually use Amazon to recommend titles to me. And ofcourse trust a good circle of friends who are into the same "styles" - mostly disturbed mental f*ck books. So, yeah, Kurt Vonnegut is in that criteria.
Check out my little free web site - www.bibliophil.org - helps you track what you've read, and make a circle of friends who can recommend books to each other... That's the whole idea.
