Though it doesn' t seem likely for twins to have the same middle name, it' s clear that Castor and Pollux Stone both have " Trouble" in that spot on their birth certificates. But anyone who' s met their grandmother Hazel will know they came by it honestly.Join the Stone twins for a laugh-filled ride as they connive, cajole, and bamboozle their way across the Solar System in the company of the most high-spirited and hilarious family in all of science fiction. This light-hearted tale has some of Heinlein' s sassiest dialogue. Oddly enough, it' s also a true example of family values-- for when you' re a Stone, your family is your highest priority.
