"The boys of Huaxia dream of pairing up with girls to pilot Chrysalises, giant transforming robots that can battle the aliens that lurk beyond the Great Wall of China...When 18-year-old Zetian offers herself up as a concubine-pilot, it's to assassinate the ace male pilot responsible for her sister's death. But when she gets her vengeance, it becomes clear that she is an Iron Widow, a rare kind of female pilot who can sacrifice males to power up Chrysalises instead"-- Provided by publisher.
