A Brutalized Soul Set on the Innocent

I've written this story 3 different times. This time I wanted to completely redo the whole entire thing.

Casey is Brian's only daughter, and oldest child, there's just one problem: Brian hates her. He beats the shit out of her on a daily basis, threatening to kill her she ever tells anyone. She's stuck in this life of misery, that is til Zacky comes along and promises he'll get her out of this life and away from her psychotic father. What will happen to Zacky and Brian's friendship, the relationship within the band? And will Brian change before he seriously injures his daughter for good?
