The Daughters of Zeus and Poseidon

An orphan girl. Forced to live and work with people who see her as less than human. Forced to sell her human dignity to get by. A pair of storm-filled eyes in a sea of overcast pupils. A bowed head in an ocean of fearful worshippers. The ones who were in practice the gods of this world didn't see her. They drowned themselves in excesses as all flawed gods do. They stepped over the heads of mortals, humans and demigods alike, to get what they wanted. Our protagonist is losing hope. Then she meets a woman with blood smeared all over her mouth and run down her chin.
