1950s England. Five-year-old Gracie Scott lives with her Mam and next door to her best friend Billy. An only child, she has never known her Da. When her Uncle Joe moves in, his physical abuse of Gracie's mother starts almost immediately. But when his attentions wander to Gracie, an even more sinister pattern of behaviour begins.

As Gracie grows older, she finds solace and liberation in books, poetry and her enduring friendship with Billy. Together they escape into imagination. But will fairy tales be enough to save Gracie from Uncle Joe's psychopathic behaviour – and how far will it go?
