Persephone, born into an aristocratic family, can't find her place in society. One day, she meets a man she doesn't know when she's out horseback riding. She abruptly runs away the moment she sees the man's piercing beautiful eyes, but he captures her in his castle in the valley. Scared at what he might have planned for her, Persephone finds out that this man, Hades, is actually a handsome, highly educated, sophisticated man. She's sent back home safely a few months later and now she's ready for the Season. She's completely taken aback by a marquess she meets there—it's Hades!
