Twenty-two years ago, Sam and Dean Winchester lost their mother, who was killed by a mysterious evil force. As they grew up, their father told them about demons that lurk in the dark and roam the country roads of America. And he also told them how to deal with them... Residents of Laurel Hill, New Jersey, seem to be the most unlucky people in the world: accidents in their town are a common occurrence. But the Winchester brothers suspect there's more to it than just bad luck. Together with Bob Singer, Sam and Dean discover that a powerful Japanese evil spirit has taken over the city and is wreaking havoc. The monster has big plans, and the heroes really need luck to defeat him. Luck is in a place where no one has been lucky for a long time. The book takes place during the seventh season of the series, between the episodes “Season seven, it's time to get married!” and “How to Win Friends and Influence Monsters.”
