Halloween is a wild, weird night in the lonely moorland towns of the north. It's dark and cold, and cracks can open up in the fabric of the safest world.

Davey Bell has been trying to live safely. He's struggled through a rough adolescence and has a decent job, a home of his own. He agrees to a meeting with his ex, even though Burdo got him into so much trouble in the past.

But Burdo has plans, armed robbery among them. When Davey recoils from his efforts at blackmail, Burdo swears he'll track him down. There's something inhuman about Burdo's rage, and Davey panics and runs from him. The town is small, the darkness beyond it absolute. Davey has lived there all his life, but he takes a wrong turn on the moorland road and is suddenly lost.

It's the first night of winter and set to freeze hard. Not much chance of survival for a man without shelter, a man on the run from his past... Then Davey stumbles into the forest, and his fears of Burdo and the cold dissolve to nothing at the sound of deep, bestial growls.

The moon is full. Ancient moorland legends are coming to life in its silvery radiance. Out of the woodland steps a strange young man, and the snarling beasts fall back. He's offering sanctuary, but at what price? He's the most beautiful creature Davey has ever seen. If Davey follows him in fascination through the gateway of Wolf Hall, what secrets will unfold before the dawn?
