The bad reputation of Kat Gray

This is my first time writing a story in english and not in my native language, so I hope you don't get a stroke trying to read it.
(Please, if you find grammar/syntax mistakes, tell me. Thank you<3)

Kat was born in London, her parents split when she was still very little because of her mother's alcoholic tendencies. Her father was a dick and she hated his new wife with all of her being. She grew up with music, thanks to her mother, before she disappeared and never called her back. Her soul was made of rock, her fingers just wanted to play guitar and her mind was composed by song lyrics. When she was 15, she understood she had to be music itself. And so it was.
