In ancient Greece, Raven, blind in her left eye since childhood, endured endless contempt and cold stares. Three years later, she has become a striking, capable princess who stands on her own. One day, she is devastated to learn that her adoptive sister Lark, the holy maiden, has fallen into the sea. Soon after, she discovers the truth: Lark was pushed off the palace rooftop by their brother-in-law Darius and Raven's own husband's sister Vesper, who conspired to make it look like an accident. But her biased parents refuse to seek justice—instead, they recognize the murderers as the new princesses. Raven decides to sever ties with her family and her useless husband. In the end, she secretly lays out a full-scale chessboard, toppling the royal power of two kingdoms. Along her path of revenge, she unexpectedly gains custody of Lark's blind adopted daughter. Ultimately, she exiles all her enemies to the desert border, where they meet their retribution by turning on each other.
