On the planet Athshe, there is no word for war, there is no concept of murder, there is no language of hate. The world is one vast, green, gentle forest full of people who live between the world-time and the dream-time, who resolve their conflicts by means of ceremonial singing. Then the Terran League discovers Athshe's existence and a pattern of "colonization"-very similar to the exploitation of "primitive" cultures on Earth-begins to destroy the planet and its people; and, eventually, one young Athshean named Selver learns how to hate.
