Fantasy:
The Book of Joby - by Mark J. Ferrari (stand-alone)
Once A Hero - by Michael A. Stackpole (stand-alone)
The Fionavar Tapestry - by Guy Gavriel Kay (completed series)
The Age of Unreason - by J. Gregory Keyes (completed series)
SciFi:
Hyperion - by Dan Simmons (completed series)
The Gap Cycle - by Stephen R. Donaldson (completed series)
The Anubis Gates - by Tim Powers (stand-alone)
The Doomsday Book - by Connie Willis (stand-alone)
Some of those could probably be flip-flopped between genres, but I don't really get that worked up about labels.
