Twenty-two years ago, Sam and Dean Winchester lost their mother, who was killed by a mysterious evil force. When they grew up, their father told them about demons that lurk in the darkness and roam the country roads of America. He also told them how to fight them. People are dying in Tahoe National Park. The Winchester brothers and their friend Bobby Singer have to track down and catch a monster that feeds on human flesh. They are faced with the walking dead, disemboweled bodies, attacks by a mysterious flying creature... and, finally, a meeting with a cunning and dangerous enemy who can take on human form and is ready to do anything to survive. Who can you trust and who can't? There is no answer to this question yet. A snow storm begins. Hunters of evil spirits will have to fight not only the monster, but also the raging elements. The events of the book take place between the episodes “Darlings scold - only have fun” and “Deadly reading” of the 7th season of the TV series “Supernatural”.
