Onna Kaizoku Queen Barbarigo

The Caribbean Seas of the 18th Century was a golden era for pirates. One of the most legendary was Barbago, a merciless murderess who was said to have killed a thousand men. Now that very same murderess has been apprehended. On the pearl white skin of her back a mysterious treasure map is discovered. Curiosity and greed trump the rules of law, and Barbago's execution is stayed until they can make her spill her secrets. She's not going to give up the location of the treasure. But the men who want it are willing to do far worse than kill her.
