What I want to see from this: a continuation in such that shows what she's been up to after the ending, the comedy of her getting used to the world around her, and maybe some other fun stuff, like any agreements she has for legal feeding, alternatives to human blood, maybe a job at the prison feeding on those in death row? It would make for quite the serialization if ever done.
After reading this story I seriously want to go and write now. It opened up a world of ideas to me.
