Falsely accused of murder, impoverished Elodie Dantès is torn from her childhood love, Killian, stripped of her most valuable possession—a forbidden artifact that wields ancient power—and banished to the otherworldly prison of Autremonde. Awaiting certain death in a world poisoned by magic, Elodie meets an unexpected ally, and together they begin digging for an escape. However, once Elodie is finally free, she discovers that the very people who betrayed her are those she trusted the most. Consumed by vengeance, Elodie develops a plan to ruthlessly destroy them all. But all too soon, she is forced to choose whether vengeance is worth the price, especially if it means losing the love of her life forever.
