Everything about Joanne and Samantha Middleton’s perfect life is all about to change, and a freak confrontation on Hampstead Heath with a tragic, deluded loner – Wayne Terry – is only the beginning.

Terry is an abused social misfit whose misery has caught the eye of a malevolent entity seeking to use the young man’s dark past and loathing for its own, bloody ends, and those ends involve Joanne’s only child, nineteen-year-old Samantha.

A menacing cycle has begun. Forced to leave their Hampstead home following a series of terrifying supernatural events, Joanne and Samantha flee to their second home, an idyllic country retreat set in a secluded Hertfordshire village.

But can a simple country cottage keep Samantha safe from a relentless nightmare, or will a seemingly random encounter with a well-meaning family hold the key to saving the most important thing in Joanne’s life?
