The Old Drift by Namwali Serpell

On the banks of the Zambezi River, a few miles from the majestic Victoria Falls, there was once a colonial settlement called The Old Drift. In 1904, 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 his fate with those of an Italian hotelier and an African busboy. So begins a cycle of unwitting retribution between three Zambian families as they collide and converge over the course of the century, into the present and beyond.
