All of Chuck Palahniuk's stuff is good (the author of Fight Club), some of my favorites by him are Choke, Lullaby, and Fight Club of course.
Anthony Burgess writes a lot of cool stuff, most notably A Clockwork Orange.
Arthur C. Clarke's Space Odyssey series (2001, 2010, 2068, and 3001) is a good sci-fi read.
Those are some that come to mind right now, I might add some more later.
