In 1668, fifteen-year-old Kemosha is sold by a slave owner to a tavern keeper in Port Royal, Jamaica; the "wickedest city on earth." She soon flees from a brutal assault and finds herself in the company of a mysterious free Black man, Ravenhide, who teaches her the fine art of swordplay, introduces her to her soul mate, Isabella, and helps her win her freedom. Ravenhide is a privateer for the notorious Captain Morgan aboard his infamous ship, the Satisfaction. At Ravenhide's encouragement, Morgan invites Kemosha to join them on a pillaging voyage to Panama. As her swashbuckling legend grows, she realizes she has the chance to earn enough to buy the freedom of her loved ones; if she can escape with her life.
