Sera, the scorned Siren princess of Atlantis, is forced by fate to serve Ares ninety-nine times for an old rescue. The war god thinks she is a shameless worshipper, making her dance on bleeding feet, crawl before Aphrodite, and nearly drown for a false crime. But every humiliation cracks the contract. When Sera finally repays the debt, she returns to the deep sea as royalty. Only then does Ares learn she was his true savior, his obsession, and the princess he can never own again.
