About the book: 2023 / Twenty years have passed since the nuclear disaster. There are new hosts on the surface: mutants and radiation. The remaining people are building a society in the underground stations of the light rail line. Here the station is a city, and their association is a whole state. This is where the story of Sam begins - an experienced stalker who specializes in finding precious artifacts of a bygone civilization. Sam has long been tired of this work and is about to retire when he receives a mysterious offer of a new order from a strange stranger who introduces himself as a member of the powerful Military Alliance, which has long disappeared from the radar. This order, at first glance, is nothing more than just a profitable deal, but in fact, the lives of not only the military, but also all the inhabitants of the dungeon do not depend on it.
