When six boys, all members of the Intergalactic Service Club, discover a mysterious portal and a notebook of instructions, they learn there is more to the obscure small-town club than service projects and outdoor activities. They discover that history repeats itself on other planets and that the club has a charge to help correct historical glitches.
But once they embark on their first intergalactic adventure, they quickly find themselves in a dangerous world with menacing enemies. Will their differences doom their chances of completing their mission? Or will they grow from their encounter with the mission planet's equivalent of one of Earth's great heroines, learn to work as a team, and help her reunite with her family?
