On the night her father gambles away their last remnant of a ruined legacy, Elera Kvoss braces for debt collectors, humiliation, or even prison.She never expects Lucien Virelli.A reclusive billionaire feared by governments and whispered about in shadowed circles, Lucien arrives at her crumbling family estate like judgment made flesh—cold, controlled, and untouchable. When he declares she now belongs to him, it is not a threat. It is a fact.Desperate to save her father from total ruin, Elera signs the contract he places before her:One year of marriage. One heir. No questions asked.She believes she has sold herself to a ruthless man.She has no idea she has married something far more dangerous.Lucien’s mansion is breathtaking, silent, and deeply wrong. Shadows linger too long. Locked doors seem to whisper at night. Servants refuse to meet her eyes. Ancient symbols begin appearing on her skin while she sleeps—marks no doctor can explain and no priest will name. She hears chanting through walls that should lead nowhere and wakes with bruises shaped like hands that never touched her.Worst of all, Lucien watches her like a man standing between her and an executioner only he can see.The truth emerges in fragments: Lucien is not cruel. He is restrained. He is not protecting his reputation—he is protecting her.Generations ago, his bloodline forged a pact with something ancient, patient, and hungry beneath the surface of the world. A pact sealed with promises written in human souls.And Elera is the final payment.She was never chosen by chance. She was born for this.Time is running out.The entity bound to Lucien’s lineage has waited centuries to claim its due, and it will wait no longer. It stalks her through mirrors, breathes down her neck in empty corridors, and whispers her name like a lover calling its bride home.The closer she grows to Lucien, the stronger the entity becomes—feeding on fear, desire, and the fragile bond forming between them.Lucien should surrender her. Her sacrifice would free him, granting him unimaginable power and immortality.Instead, he does the unthinkable.He refuses.As forbidden rituals awaken and dark enemies close in, Elera discovers the most terrifying truth of all:The monster the world fears is the only thing standing between her and something far worse.And when Lucien whispers against her skin, “If the devil wants you, he’ll have to fight me first,” she no longer knows which fate is more dangerous—being claimed by the demon… or being loved by the man who defied it.
