“O devil of my Ducommun ancestors— please stop this marriage...!” The twin sister—Giovinetta Valdemar, or Lady Devil herself, branded as such after her husband’s heart was ripped out on their wedding night. The twin brother—Johannes Valdemar, the exalted hero and shining sun of House Valdemar. Torn from Johannes by their mother as children, Giovinetta can only glimpse her unrestricted brother through the single window in the room where she’s kept under lock and key. So when Giovinetta is next betrothed to a much older nobleman, the fear of yet another cage drives her to make a desperate plea for help to the devil of Ducommun—a wish that is answered by transforming Johannes into a devil himself! Will this creature be her salvation or lead them both down a treacherous and forbidden path?
