They step out into a world colder than any human has ever known. They walk towards the light. They find not a city, but a small, geothermally heated research station, powered by a different kind of engine—a deep-earth thermal borehole. Inside are a dozen scientists, descendants of a failed Arctic outpost, who never knew the train existed.

Seven years later, the train is a rigid, brutal class system on rails.

In the Tail, a former homicide detective named clings to a secret: before the freeze, he was part of a failed rebellion that saw his wife executed by being thrown from the train. Now, he’s been summoned to the front. The Head of Hospitality, a calculating woman named Melanie Cavill , has a problem. A body has been found in the First Class—a Jackboot officer, brutally murdered with an ice-pick. No one in First Class could have done it. The killer must be from the Tail. She needs Layton’s detective skills to find the murderer before panic spirals.

Layton discovers the truth: the murdered officer was part of a secret network selling drugs into the Tail. More importantly, the killer is a hero—a Tailie named , who is also Layton’s former lover. But before he can expose her, she reveals an even deeper secret: the resistance has a new plan. They’ve found a way to jam the train’s doors open simultaneously.

A signal fire.
