Xanth- Spell for Chameleon and Source of Magic is all I've read thus far, and yea its pretty excellent!!
Could also try the Myth series by Robert Aspirin.
I read Pool of Radiance (Forgotten Realms) and that's pretty damn good.
you can't go wrong with some Margaret Weis, Tracy Hickman, RA Salvatore, or Terry Brooks as well.
I just started my first Shadowrun novel 'Nights Pawn', I'm looking to get into the Never make a deal with a Dragon books next. Damn fine stuff here, mixes the scifi futuristics with magic and fantasy from medieval times
good stuff, good thread. gonna look around for some of those suggested!
