Undercover badass

About a girl named Tilly and how she has a secret. At school she's a nerd but outside of school she is a badass. She is a street fighter, a gang leader and a street racer. What happens when the bad boy notices her and wants to find out more about her? Will her secret stay a secret? Will the bad boy fall in love with her?

First story so don't kill me if its rubbish. My grammar is okay so no need to worry about seeing misspelt stuff. I hope you enjoy😄
