Where do I start? Most anything that's Sci-Fi or Fantasy. Some of my favorites are Roger Zelanzy for his Amber series Terry Brooks for Shanara Anne McCaffrey for Pern series Robert Jordan for Wheel of Time Phillip Jose Farmer for World of Tiers JRR Tolkien for Lord of the Rings Mary Stewart for her Crystal Cave series Battletech novels D&D novels lost my Riftwar series so I can't remember the author and a ton of others
