So I am looking for a fan-fiction/game of the plot The Quiet which revolves the plot around a deaf girl moving into her god-parents house after her father dies. She starts to realize that the daughter of the family is being emotionally and sexually abused by her father and the daughter starts to confine in the dead girl. There kind of a weird relationship between the two girls but it gets to be strong. At first the the daughter is a bitch to her, realizes she is pretending to be deaf and still confesses she is going to kill her father. The movie ends with the daughter not being able to but the deaf girl does and they help each other in the end.
I kind of wanted a similar plot but maybe a relationship between the two girl characters.
