Anne Rice, Amelia Atwater-Rhodes, and Charles De Lint.
Anne Rice is my all-time favorite writer. I haven't yet read everything she's written, but I would like to.
Amelia Atwater-Rhodes is also one of my favorites... I was actually somewhat disappointed by her more recent books, but I'll still read anything else she writes in the future.
So far I've loved everything that I've read by Charles De Lint; as far as I know, everything he's written has sort of the same fantasy and mythology-related themes, so I always know that I'll enjoy his stories and books.
