Any Terry Pratchett- particularly the Night Watch and Witches books.
Raymond Feist
George R.R. Martin (already mentioned)
I can do nothing but agree here, especially Feist, I just reread some of his books and they're still amazingly well written. hard to find books written better then those I think.
Terry goodkind also deserves a place here I think. his sword of truth series is nearing it's climax and I cannot wait as it's also great.
David eddings then, with the belgariad and the mallorean created a beautifull world. and his characters are equally beautiful.
