Human vs Android/Robot world. Humans are hunting robots. Lead is a female character who finds out through the course of the story that she's an android herself and is the key to solving the human/android problem.. I believe it was that she could give birth.
Anyway, she finds her "father" who tells her this and then gets an "upgrade" of sorts at the end to take on a huge army. She might have died or come close to dying at the end.
