Two of my favorite books series are The Dragonriders of Pern by Anne McCaffery and the humorous series the Myth Adventures by Robert Asprin.
Anne McCaffery's series starts with "Dragon Flight ", "Dragon Quest" and "The White Dragon" there are now over a dozen books in the series.
Robert Asprin's Myth Adventures begins with "Another Fine Myth", "Myth Conceptions" and "Myth Directions". Anyone that enjoys Tolkien, Fantasy or Dungeons and Dragons is likely to enjoy Asprin's comical look at mythical fantasy storytelling.
