Brutal attacks. A sinister conspiracy. Time is running out.

In the quiet seaside town of Weston-super-Mare, a man is found unconscious on the beach with a strange symbol carved into his skin. The victim - a local drug addict - has no recollection of who attacked him or how he got there.

The sleepy coastal community is sent into shock. And when another victim branded with the same vicious mark dies from his wounds, DI Louise Blackwell realises she is dealing with a sadistic serial killer.

But why is the twisted attacker targeting Weston’s most vulnerable people? And what is the meaning behind the mysterious symbol? Still struggling to overcome her own demons in the wake of her brother’s death, Blackwell must stay one step ahead of both the killer and corrupt DCI Finch, whose meddling in the investigation makes her more determined than ever to bring him down for good.

As the body count rises, and her feud with Finch puts her own life in danger, Blackwell faces a race against time to discover the dark crime that unites the victims and put an end to the carnage - before someone puts an end to her.
