Barnaby Brocket is an ordinary 8-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 horror 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. From Brazil to New York, 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.
