When the bells fall silent, the mountain begins to breathe. Mariselle's fire and Seraphine's river are no longer curses whispered in dreams but weapons the Ash Mother aches to claim. In a city turned graveyard and forests that remember old vows, Ronan and Kaelen swear the only promise despair can't twist: choose each other against the dark—until dawn, and then again. But cult lanterns burn green, chains drink grief, and prophecy sharpens its teeth: one will bind, one will break... both will love. To unmake the Ash Mother's rising, the sisters must learn to bend what would devour them—and sever the chains that call one of them bride.
