Six Times The Machine by Zaraen reviews
She was ready for her final stand. Ready to take as many as those alien bastards down as she could. Only, things didn't turn out how she expected. Death didn't claim her and now she's on the one planet they all swore to protect, but there's one difference. Someone else found it and now she's an alien to her own heritage. A machine in the eyes of this Humanity. Then there's that AI.
