DI Kelly Porter is about to discover just how dark things can get in the Lake District.

When a young woman is found unclothed, unspeaking at an ancient stone circle it's not clear if any crime has been committed. DI Kelly Porter and her team start looking into the circumstances, but the mystery girl disappears.

Soon after, a brutal murder is committed and sinister markings at the scene indicate that the killer had a message. The investigation reveals that in the beautiful Lake District there are those who believe in ancient ways, and within those circles old resentments are spilling over into terrible violence.

Kelly has all the pieces to solve the puzzle, but to put them together she must confront a figure from her past: one who nearly destroyed all that she holds dear.

Will she avoid the same fate this time, or can the killer stay one step ahead of her to the bitter end?
