There's been a discussion this week on the email loop for the Beau Monde, a chapter of Romance Writers of America that caters to authors who write books set in the Regency. Do readers of Regency historicals mind if the books have paranormal elements, ie., ghosts, vamps, werewolves, time travel, etc.?
Personally, I won't read them. It's just my own personal prejudice. I want real stories, but not really. Unless Cinderella stories are really real.
