I think that this will be a good story. I will sujjest that instead of jumping straight into athikened plot that you give your character a life and a personality. Give 3 or 4 chapters to giving her a personality and setting up your plot. Some Authors give 3/4 of their books to setting up their plot. These are well liked and famous authors. Many people (writers) these days just jump staight into a thickened plot without preparing it. Think of your story as making Jello or pudding. Before you thicken it at all, you need to prepare everything.
