Theo Byrne is a promising young astrobiologist who has found a way to search for life on other planets dozens of light years away. He is also the widowed father of a most unusual nine-year-old. His son Robin is funny, loving, and filled with plans. He thinks and feels deeply, adores animals, and can spend hours painting elaborate pictures. He is also on the verge of being expelled from third grade, for smashing his friend's face with a metal thermos. What can a father do, when the only solution offered to his rare and troubled boy is to put him on psychoactive drugs? What can he say when his boy comes to him wanting an explanation for a world that is clearly in love with its own destruction? The only thing for it is to take the boy to other planets, while all the while fostering his son's desperate campaign to help save this one.
