Fourteen-year-old Zack Gilman is not what you'd call a happy kid. The mild-mannered son of the world's biggest Minnesota Vikings fan, he is doomed to spend his days being dragged to football games, where he's forced to sing fight songs and make bratwurst runs for his dad's boisterous posse. The problem is, Zack hates all organized sports. The other problem is, he's six-foot-three, weighs 250 pounds, and his dad sees him as the next Vikings football MVP. It starts out as an ordinary day at the Minnesota Metrodome. When Zack is nominated vice president in charge of bratwurst by his dad's football cronies, he grudgingly sets out on a food run, only to find himself caught in a freak snowstorm. Zack loses his sense of direction and literally stumbles upon a strange key-like object. The moment he picks it up, Zack find himself in another world, another time, and on an adventure he never bargained for.
