When runaway slave Y/N escapes with nothing but her late father’s mysterious necklace, she never expects to end up aboard the flagship of the Pirate King. After invoking an ancient pirate bloodright moments before her execution, she is spared and taken under the protection of twenty-four-year-old Pirate King Nathani Blackthorne, all while hiding the fact that she is not the son of Thomas Reed, but his daughter. As rival Pirate Lords pressure Nathani to choose a wife, a ruthless governor hunts Y/N for the secret hidden within her necklace—a secret that may lead to the legendary lost city of Atlantis and change the fate of the seas forever.
