Cassandra Williams is 12, and her little brother, Wayne, is seven. One day, when they’re alone together, there is an accident and Wayne is lost forever. His body is never recovered. The missing boy cleaves the family with doubt. Their father leaves and starts another family elsewhere. But their mother can’t give up hope and launches an organization dedicated to missing children. As C grows older, she sees her brother everywhere: in bistros, airplane aisles, subway cars. Here is her brother’s face, the light in his eyes, the way he seems to recognize her, too. But it can’t be, of course. Or can it? Then one day, in another accident, C meets a man both mysterious and familiar, a man who is also searching for someone and for his own place in the world. His name is Wayne.

1904. On the banks of the Zambezi River, a few miles from the majestic Victoria Falls, there is a colonial settlement called The Old Drift. In a smoky room at the hotel across the river, an Old Drifter named Percy M. Clark, foggy with fever, makes a mistake that entangles the fates of an Italian hotelier and an African busboy. This sets off a cycle of unwitting retribution between three Zambian families (black, white, brown) as they collide and converge over the course of the century, into the present and beyond. As the generations pass, their lives --- their triumphs, errors, losses and hopes --- emerge through a panorama of history, fairy tale, romance and science fiction.
