The Harlequin is the fifteenth book in the Anita Blake: Vampire Hunter series of horror/mystery/erotica novels by Laurell K. Hamilton; it was released June 5, 2007. Plot introduction Anita Blake is about to face the challenge of her life. Into her world—a world already overflowing with power—have come creatures so feared that powerful, centuries-old vampires refuse to mention their names.
