Piratica

Piratica: Being a Daring Tale of a Singular Girl's Adventure Upon the High Sea by Tanith Lee.

Artemesia has spent the last six years at the Angels Academy for Young Maidens. She does not remember anything of her life before coming to the school. Then, after a bump on the head, she remembers her previous life...

Her mother, Piratica, was a pirate. She was feared in the seven seas, but she never killed the people on the ships she captured. She was an ethical pirate! Art was with her mother and the crew until a canon exploded, she lost her memory, and her father sent her to boarding school.

As soon as Art gets her memory back, she discards her dresses for boy's clothes and escapes the school. Her goal is to find her mother's crew and join them.

This novel could be the typical girl pirate story if not for one twist. Art's memories may not be as accurate as she thinks. Was her mother really a famous pirate? Or is her memory playing tricks on her?
