Iron Widow | Xiran Jay Zhao

The boys of Huaxia dream of the celebrity status that comes with piloting Chrysalises - giant transforming robots that battle the aliens beyond the Great Wall. No one cares that their female co-pilots must serve as concubines and sacrifice their lives. When 18-year-old Zetian offers herself up as a concubine-pilot, her plan is to assassinate the man responsible for her sister's death. But on miraculously emerging from the cockpit unscathed after her first battle, she has a new plan. The time has come to overturn the entire patriarchal military system.
