Wow. OK. Let's see...
Anything by Terry Pratchett.
Anything by Orson Scott Card.
Anything by Alastair Reynolds (*amazing* sci-fi - you've got to read his "Revelation Space" novels, starting with Revelation Space.)
Anything by Neal Stephenson (Anathem is great, try _Snow Crash_ or _Diamond Age first.)
Anything by Robert A. Heinlein
Anything by Tim Powers (this guy will blow yer mind! I recommend starting out with _Last Call_)
China Mieville - The Scar, Perdido Street Station
Peter F. Hamilton - Night's Dawn Trilogy (*epic* sci-fi. You'll probably find the "trilogy" broken up in to 6 books)
Right now I am concurrently reading Neal Stephenson's new book Anathem, and two re-reads - O.S. Card's Worthing Chronicles, and Alastair Reynolds Redemption Ark.
Also, hurray on 100 posts!
