But I think it needs to be changed so much that it would not really be recognizable from the story you posted. Like, I think a very good quality of story can be made using a family torn apart by a tragedy, as this one is. But for the reader to root for them or mourn for them, they have to be likable. They can't be so one-dimensional; I mean, we know nothing about these people except that the father preffrred a boy and had a contagious laugh, the mother was musical and beautiful, and the daughter is unattractive, has no friends and all we ever see her do is write and try to get people to read it. If they're developed more and show more complex personalities, I think the reader might like to read about them.
