Plot summary
Mark London is now president of the settlement. He has forced the people to abandon all technology and become a simple, agricultural community full of taboos. Upper Isis is now a forbidden zone, because, so they believe, the Guardian put a curse on the mountains, imprisoning the people in their own valley. One boy, Jody N'Kumo, grandson of one of the original settlers, breaks one of the most sacred taboos, and is banished to the land of Guardian, although everyone knows he is simply being sent to his death. However, Jody does not die, and discovers a place called Bamboo Valley. There he meets the Lady Olwen, who was the Keeper of the Isis Light in the times before the colony, and learns the truth about the history of Isis.References
