Beth Henderson sought vengeance for her brother's brutal death. What she found was a nightmare older than memory.

Mickey "The Mallet" Henderson was hard to kill. What the police find on the moor isn't just a body - it's a ruin, frozen from the inside out. For DI Arlo Carver, it's the start of an investigation into impossible violence. For Mickey's sister Beth, it's a call to arms.

But the killer isn't human. It's a shadow moving through the dark, an entity of absolute cold drawn to the heat of rage and violence. It hunts the hunters, the strong, the dangerous. And it leaves behind only frost and terror.

When the entity brands Beth, forging a psychic link that bleeds cold into her soul, she becomes its greatest challenger and its most desired prey. Teaming with a cynical detective and a scholar of the forbidden, Beth is thrust into a desperate battle against a force that defies understanding. A force that evolves, learns, and spreads - first as a god of frost, then as a chilling, adaptive intelligence blooming in the vulnerable.

How do you fight winter itself?

A visceral, terrifying journey from the desolate moors to the heart of a glacial tomb, where the cost of survival is etched in frost and silence.
