And now for something Totally off topic :)

Here goes:

Stephen R. Donaldson - both the Thomas Covenant series and the "Gap" series.

Frank Herbert's Dune series (I'm working through "House Atreides" now; I own all but Chapterhouse: Dune, the weakest of the series IMHO).

Older Asimov stuff (Robot, original Foundation trilogy, etc.)

A little bit of Heinlein

The entire "Known Universe" series by Niven (of course)

"The God Particle" by Lederman (quantum physics)

"Flatland"

"A History of Time" by Hawking

"The Existential Pleasures of Engineering" by Florman

Couple different series of modern vampire books (Laurel Hamilton's series and another series by another author that begins with an "H" - Hahn or something like that)

The Harry Potter series

I stopped reading McCaffery's Pern series a while back, but I'll probably pick it up again soon. I've read a couple of her Crystal Singer books recently, and read a couple of her Dinosaur Planet books a long time ago.

The "Phule" series by Robert Asprin (also read the "Myth" series by Asprin, very disappointed that he stopped writing them).

The "Exiles" series by Melanie Rawn.

And anything else that strikes my fancy.
