Barnaby Brocket is an ordinary eight-year-old boy in most ways, but he was born different in one important way: he floats. Unlike everyone else, Barnaby does not obey the law of gravity. His parents, who have a fear of being noticed, want desperately for Barnaby to be normal, but he can't help who he is. And when the unthinkable happens, Barnaby finds himself on a journey that takes him all over the world. Drifting from Brazil to New York, from Canada to Ireland, and even to space, the floating boy meets all sorts of different people--and discovers who he really is along the way.
