For centuries, Everlys have seen their brightest and best disappear, taken as punishment for a crime no one remembers, for a purpose no one understands. Their tormentor is a woman named Penelope, who never ages, never grows sick - and never forgives a debt. Ten years ago, Violet Everly's mother left to break the curse, and never returned. Now Violet must find her mother, or she will be taken in her place. Her hunt leads her into a seductive magical underworld of power-hungry scholars, fickle gods, and monsters bent on revenge. And into the path of Penelope's quiet assistant, Aleksander, who she knows cannot be trusted - and yet to whom she finds herself undeniably drawn. Tied to a very literal deadline, Violet will travel to the edges of the world to find her mother and the key to the city of stardust, where the Everly story began.
