1686. The English girl Mary is seven years old and she is an angel. At least that's what her mother thinks. To provide her daughter with a comfortable life and a good education, she marries her as a boy. Time passes, and Mary already fences better than her mentor, is as strong and dexterous as any guy, and will never agree to exchange men’s clothes for girls’ clothes. Angels have no gender, but Mary is destined to become a beautiful woman, captivate the minds and hearts of the most worthy men, inspire love and... mortal hatred. It all started with an adventure. The chase - and now Mary is already on the ship. Boarding - and her life in the hands of French corsairs. There, among them, she will first experience the thrill of battle, and her further fate will turn into a series of sea battles, love battles, pirate raids and dizzying adventures.
