Too many zombies. If anything, zombie movies, books and tv shows eat our collective brains. Research shows that wvery hundred pages, (movie or two episodes) kills more brain cells than a six-month drunken binge.
Sexy vampires, and werewolfs too.
I could read a book about a sexy leper. If it isn’t a romance. It would have to be an attraction that bewilders and repels even as it compels the protagonist.
