An adventure in colonization and conflict from acclaimed SF writer Pamela SargentSeveral hundred years ago, Ship, a sentient starship, settled humans on the planet Home before leaving to colonize other worlds, promising to return one day. Over time, the colony on Home divided into those who live in the original domed buildings of the colony, who maintain the library and technology of Ship, and those who live by the river, farming and hunting to survive. The Dome Dwellers consider themselves the protectors of "true humanity" and the River People "contaminated," and the two sides interact solely through ritualized trade: food and goods from the River People in exchange for repairs and recharges by the Dome Dwellers.Then a new light appears in the night sky.
