I love most anything by Bret Easton Ellis (American Psycho and The Rules of Attraction are his best).
The House of God (If you're at all into medicine and enjoy satire)
Trainspotting by Irvine Welsh (written in scottish phonetics)
Dean Koontz, they all follow a similar formula but it's fun thriller/suspense
Snow Crash by Neal Stephenson (CGI universe, offbeat humor, Cosa Nostra Pizza), Cryptonomicon is good as well, part cryptography, part WWII, part modern indiana jones.
