I shouldn't want this

Jay is just a normal person. Well not really, she's immortal. Her mission is to kill Eyeless jack. She thinks it will be the easiest thing. That is until she gets there. He's nothing how she remembered. And even worse than that she can feel herself falling. And hard. But what happens when everything turns around? And for the worst? And the one person Jay never wanted to see again appears? Will Jack forgive and forget? Or will this be the end of their forbidden love?
