I have too many damn favorites. But here is some anyhow.
The Memoirs of Cleopatra, by Margaret George.
The Autobiography of Henry VIII, Margaret George.
the entire Elric series by, Michael Moorcock.
The Mists of Avalon, Marion Zimmer Bradly. She also did some damn fine science fictions that are real good, but very hard to find. Found one at the library, never saw any again.
IT, Tommy Knockers, Insomnia, The Stand, just a shit load of Stephen King.
The entire incarnations of immortality series by Peirce Anthony. Well the last was kind of meh, but the rest of the series was well worth it.
I will repeat the Dragonlance Chronicles, by Margaret Weis and Tracy Hickman, because its all bad ass.
Dragon Doom, by Dennis L. McKiernan
Fave Anne Rice vampire series book, Pandora. Most shitty Anne Rice book for good measure, Violin.
Weird, nassty and some parts strangely arousing, The claiming of sleeping beauty.
The Chronicles of Amber, Roger Zelazny. My second fave fantasy books of all time.
I probably forgot some, but this is a basic list.
