Arthur Baptiste knows little of Rwanda's past and is unaware of its emerging troubles. He lives with his half-Tutsi, half-Belgian father and English mother on a flower plantation, where he talks to no one - not even the butterflies he avidly collects. Beni, the cook's granddaughter, is a child much like Arthur, but one who lives in a world far different from his own. Their friendship will take them from innocent adventures to dangerous encounters and on towards dark revelations. As the years pass and conflicts erupt outside the plantation, Arthur comes to realize that the safe haven of his childhood and the entire country around it is about to be torn apart.
