Erol--
I thorougly recommend Varley's Gaea Trilogy:
Demon, Wizard and
Titan.
I've enjoyed most of his later work, but I'd never classify it as Personally Beloved.
Thanks for your comments and suggestions. Some days I feel like a Voice in the Asteroid Belt.

Lois McMaster Bujold's "duology"
The Sharing Knife: Beguilement and Legacy comes to a puzzling conclusion.
Beguilement establishes two interesting characters, a solid plot and some interesting speculation about mental gifts.
Legacy seems to be more of a second-volume-of-three than a concluding book, but when I checked LMB's website I didn't find any indication that a third volume is forthcoming.
LMB is best known for her Hugo and Nebula award winning books featuring Miles Vorkosigan, the most endearing homely hero since Cyrano deBergerac swaggered down the pike.
The Dendarii website below offers a number of free first chapters
