At kilometer 6,843, deep in the Siberian taiga, the rail snaps under the wheels. It is forty below. The radio is dead. Freight convoy B-47 will go no farther.
Fifty-six passengers — laborers, engineers, a doctor, a former officer — wait for a rescue that doesn't even know they're stranded. The first night, a man vanishes. The second, all they find is frozen blood. Something is circling the train: something that learns, that chooses its prey, and that matches no species on record.
Captain Sergei Volkov holds the line against panic the only way he knows — through discipline, and choices no rulebook allows. But what hunts them in the dark isn't the only question. There is the sealed military car no one is permitted to open — and the reason this train should never have stopped here at all.
A chilling survival horror braided with military thriller, where nature has no name — and the State would rather it stayed that way.
