Artemesia is the daughter of a pirate queen, and she's sick of practising deportment at the Angels Academy for Young Maidens. Escaping from the school, she hunts up her mother's crew and breezily commands them out to sea in a leaky boat. Unfortunately, Art's memories of her early life may not be accurate-her seasick crew are actors, and Art's infamous mother was the darling of the stage in a pirate drama.
