About the book: 2021 / 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. A brutal murder occurs in Braden Heights, Indiana. Local authorities believe that the unfortunate man was the victim of a wild animal attack. But when another mutilated body is found, the Winchester brothers and Castiel begin to look for a connection between the dead and find out that they were soon to become fathers. As they hunt for the killer, the Winchesters uncover stories from the town's troubled past and secrets that some say would be better off buried forever. The book takes place between the episodes "Was There a Boy?" and "Halt and Catch Fire" from Season 10 of Supernatural.».
