There's Blood On The Dance Floor (A BOTDF Fanfic)

Azrael's life isn't the easiest thing in the world - her mother calls her a slut on a daily basis, she doesn't remember anything about her father since he has been in prison since she was a toddler, and her so called "best friend" has recently started to not like her much anymore - but one night when she's grounded, she decides to sneak out to a concert. But not just ANY concert. Her favorite band, who she owes her life to; Blood On The Dance Floor. That night, she does some things she's never even considered doing before, and it changes her life for the worst. Or perhaps, for the better?
