No one knows exactly where the "edge of the earth" is, or if it even really exists. No one knows what it’s like there, at this edge, and what lies beyond it.
Lily Molchanova is heading to the edge of the earth, to Anadyr. At first glance, it's an ordinary business trip to the radio station "Purga," but in reality, she has been sent there with a distant aim... Everything is different at the edge – cold and dangerous, and Lily, already mourning her terrible fate, suddenly finds herself in an unknown and beautiful world where people live by different laws and rules. They are used to helping and saving each other; without that, one cannot survive in the Far North!..
When Lily finds a murdered hunter under strange, incredible circumstances, a twisted and terrifying game begins. She feels that she is alone, that no one will help or save her, but suddenly she realizes – there is no universal loneliness; there are people, real, alive, decent, who are ready to save her at any cost.
