You know, for fun?
I have a somewhat respectable library myself, consisting mainly of Stephen King. I also have the complete works of Chuck Palahniuk, and a number of books by Harold Robbins because I'm a perv.
Other authors I like are Peter Benchley, HG Wells, Richard Matheson, Nick Hornsby, and Michael Crichton, even though his stories are crap.
I should like Hitchhikers Guide to the Galaxy, but I landed on Red Dwarf instead.
So what about you? I'm sure there are at least one or two other bookworms out there.
