Comment Zelazny again and a bunch of others (Score 1) 1244
Roger Zelazny is damn good.
The Amber Series (both the original 5 about Corwin and the next 5 about his son Merlin) is awesome.
but his best is the single book: A Night In The Lonesome October. That book totally kicks ass.
Plus I would highly recommend the Amber Series and A Night In The Lonesome October on audio.
They are read by Zelazny himself (except for book 10 of the Amber series as Zelazny died before he could read it). He has one of the best voices ever and since he is reading his own works, he gets the emotions, inflections, etc. perfect.
Alan Dean Foster's Shadowkeep, Pip 'n Flinx, etc.
Robert Lynn Aspirin's Myth series (at least the 1st six or eight then it got weird once Aspirin got writers block).
David Drake's Hammers Slammers and Ranks of Bronze
Keith Laumer's Bolo series (even the short story collections by other authors and a couple of books by others).
David Eddings' Elenium and Tamuli series (I was never much of a fan of the Belgariad series personally)
If you liked Robotech, the written series by Jack McKinney was pretty good.
Frank Herbert's Dune series though the prequels by his son made the series a bit better/fleshed out more.
I liked Harry Harrison's Stainless Steel Rat series though it needed to be in moderation / spread out - read too many in a row and they got harder to take
Larry Niven's DreamPark series was good.
John DeChancie's Castle series was entertaining.
Christopher Stasheff's Warlock series ( at least the first five or so) was good as was the 1st four of his Wizard in Rhyme series.
