Promised for marriage, now destined to die.

Since Sophronia's murder, princesses Daphne and Beatriz have discovered the truth: they are pawns in their mother's bid for the throne of Vesteria.

Separated with enemies on all sides, Beatriz and Daphne's only hope are the few allies who stretch across the borders of Vesteria: Sophronia's husband, the deposed King Leopold; Violie, a former spy for Empress Margaraux; and Beatriz's missing husband, Pasquale, and his lover, Ambrose. But whispers of an ancient prophecy and secrets from their past follow every move they make.

With the magic of the stars, the princesses are ready to make their final stand.
