Vorkuta is a dying city in the middle of the tundra, where in an entire five-story building, there may be only one apartment with residents. Ilya returns to his childhood city to find his brother—his true sibling—who has been gone from him for a long time. And he learns that Vovka didn’t simply disappear—he ended up in an unthinkable world called Duplication, a place where the shadows of long-dead ancestors live. Things aren’t what they seem, and everything around you is trying to kill you.
