I'm looking for a book about a girl that lives with drug addict mother and stepfather. The mother dies and the stepfather rapes the girls and prostitues her to local men in the neighborhood until the local drug lord finds out he is stealing his business and takes the girl with him. Once he cleans her up he makes her his mistress. She eventually falls in love with one of his followers. He helps her find who her father is. The drug lord has people looking for the two of them because they ran off together. Some way they end up back with the drug lord who tortures her and they enventually end up killing him.
