He really is that good. There's a few of his collections I haven't read and three stand alone novels I haven't touched. Also I should give the latter half of the Hyperion Cantos a chance again sometime.
There is a succinct tribute to the author from another writer named Jon Del Arroz. I am sure there will be many more in the future.
Depending on the genre you like chances are you'll find something you like from his forays into science fiction, crime, historical adventures, and horror. Sometimes his books encompassed at least three of those. If you haven't discovered his writing yet, I envy you.
