SISSY by Kelvin V.A Allison

Jack Stone; a middle-aged North London gangster, recently released from over two decades in prison, seeking to leave his violent past behind him.
Then the brown-eyed, dark-haired Sissy enters his life.
And Hell follows with her.

An extreme horror novel that reads like a mash-up of Natural Born Killers, The Crying Game and Snatch.
