Would you buy a book about this?

Just so you know I'm fifteen and planning on publishing a book myself so I have nothing against you. I think its great that you're dreaming big and making a goal. About the story, I think its good. But you have to make her mother's dying wish very special. And make a good reason on why she would risk everything to find her father. Did he hold something that belonged to her? Or was it just the fact that she needed a guardian? And if that's the case, you need to make it plain that all her family is dead. Also, it would make it more interesting to have the fact that her mother died in The Plague. It would make it known of that dark era in history. Otherwise, it sounds like an interesting story plot. Just remember to add more back round about the characters, and more detail. Wish the best!
