Sean O'Brien inherits an old Irish castle, believing that the rumors of its haunting by an ancestor who kept a harem are ridiculous—until the ghostly influence destroys his inhibitions. His Dom side is exposed and he's taking everything he wants from the sexy, submissive ghost hunter alone with him.

Dana Rayne is hired to cleanse the castle of ghosts but they are stronger than any she's ever faced. Sean is stunned by their effect on him but Dana is more than willing to be the sub in Sean's kinky dungeon built for sex. The ghosts refuse to leave and grow stronger as Halloween nears. As Dana and Sean explore their deepest fantasies, the ghosts attempt to act out their own deadly desires.
