Some time back I was having a great chat in Guild about favorite authors.... so I continue it here to see of any other good suggestions:
Steven Brust ( www.dreamcafe.com/main.html )
Pretty much anything by him was fun for me... especialy in the story line about Vlad Taltos
Michael Moorcock ( www.multiverse.org/phpnuke/ )
In particular, his stories about Elric. Very Very very dark sword and sorcery. He also has various other series that are interconnected... Via the Eternal Champion..(Elric is one incarnation of this eternal champion, as is Corum; Hawkmoon, Cornelius(this guy is more of a modern/future time incarnation), Von Bek, and the list goes on)
Margret Weis and Tracy Hickman (known for Dragon Lance books) are right on the top for me. In particular is the "Death Gate Cycle" A series of 7 books, that will keep you on your toes, make you fall in love with the characters, cry when they die... and well this series just @#%^ing rocks...
Fred Saberhagen's 1st, 2nd, and 3rd Book of Swords.
Piers Anthony - Xanth Series
