Book excerpt: A trip to the Moon? Sounds like the perfect family vacation. Only, for 13-year-old Charles "Chigger" Dingillian, life is anything but perfect. His parents fight so much, they put the "dis" into dysfunctional. His brothers, Stinky and Weird, are impossible to get along with. And his neighborhood is a down-trodden tunnel community on Earth. It's supposed to be a short vacation—a trip up the Line, Earth's space elevator, and then home again. Halfway there, Chigger hits on a plan: if his parents can't find a way to work things out, why not just divorce them? The idea sounds crazy . . . until it works. But Chigger soon realizes he has much bigger problems: The people they meet on the Moon seem overly friendly and way too interested in his family. Suddenly, the quick pleasure trip takes a detour into danger as Chigger suspects they are targets of an interstellar manhunt. Their only hope may be to jump off the planet.
