When her sister is dying and the doctors have nothing left to offer, Sera Voss finds an old journal and a ritual that promises a way out. At midnight she summons a demon and makes a deal: one year of her life in exchange for her sister’s full recovery. The demon who answers is not what she expected — silver-eyed, ancient, and already familiar in ways she cannot explain. He takes her to a manor that exists outside the human world. There she discovers photographs of women who share her face stretching back across centuries, letters written by her own grandmother, and the truth that she has made this choice before. What begins as a desperate bargain becomes a slow and dangerous year of forced proximity, growing trust, and an ancient force that feeds on the bond forming between them. By the end of the year Sera must decide whether to return to the human world free of the cycle forever, or stay with the one being who has waited for her across every lifetime.
