Everyone has them. Some are more dangerous than others. Some should never emerge to see the light of day – yet they lurk, poised to pounce on the unwary.

It is a dark autumn evening. Dusk is falling over a busy stretch of motorway when a reluctant traffic jam forms. This is an ordinary road, a normal – if frustrating – snarl of congestion. It is no place for demons. And yet, in the stillness, they thrive.

Living in the spaces created by stasis, they go unnoticed. The travellers, lost in thought, remain unaware of the true danger that lurks among them – something ancient, something waiting… something that dwells in their midst.
