The Immortal Part of Myself

Riley has lived her whole life as an elite daughter of one of the five ruling earthen corporations. She was supposed to be a beautiful figurehead working behind the scenes to help her husband. But the dresses they stuff her in are uncomfortable, social situations leave her confused, and she never really has been a woman. When she was diagnosed with autism, her father's only hope was to marry her off.
As she aged, her usefulness to her husband has diminished, and he plans on trading her for someone younger. Divorce isn't legal, but murder is.
