Vibia has served as a Vestal Virgin since childhood, sworn to chastity and charged with guarding the sacred flame of Vesta. Breaking her vow means death. Her ordered life collapses when she is pulled into the lethal intrigues of Emperor Domitian's court. Behind its beauty and splendor lurks Julia, charming and dangerously manipulative. Drawn into a tense triangle with the mysterious freedman Leonides and the hardened centurion Quintus Sirius Aquila, Vibia must navigate a treacherous landscape where her vows of purity become political weapons, her every action is watched, and one misstep could mean death in the clash between holiness and the corrupting force of imperial power.
