Evil Heart (Harry Styles AU)

Tottenham is an area in the London Borough of Haringey, in north London, England. Tottenham has a major crime problem and has suffered from being one of the main hotspots for gangs and gun crime in the entire UK during the past three decades.
During the past few months many girls have gone missing in the area and then found later with a gunshot to the head and unclothed. The murders are occurring like a wild fire until one night it just randomly stops.
Harry is a young man born with a heart defect, when he gets the opportunity to receive a heart transplant he is overjoyed, but will the actions that follow make him wish he had rather died instead?
