In the second novel in New York Times bestselling author Stephanie Dray's thrilling trilogy, Cleopatra's daughter seeks the power to stand against an empire ... Having survived her perilous childhood as a royal captive of Rome, Selene has pledged her loyalty to Emperor Augustus, swearing to become his very own Cleopatra. But even though she is forced to marry a man of the emperor's choosing, Selene will not allow her new husband to rule in her name. Quickly establishing herself as a capable leader, she wins the love of her new subjects and makes herself vital to Rome by bringing forth bountiful harvests with the magic of Isis flowing through her veins. As she rules the kingdom of Mauretania and contends with imperial politics and religious persecution, Selene beguiles her way to the precipice of power with the ultimate goal of taking back her birthright. But the price of winning back her mother's Egyptian throne may be more than she's willing to pay.
