Betrayed and killed by her husband and a corrupt church, Queen Hilda of Noren trades her eternal soul to a centuries-sealed demon Valler for a second life. Reborn in her handmaiden’s body, she infiltrates the palace to exact brutal revenge, unearthing the church’s dark human experiment conspiracy. What starts as a blood pact alliance becomes an all-consuming love. As Hilda reclaims her throne, Valler sacrifices his immortality for her, reborn as a mortal to stay by his queen’s side forever.
