In a post apocalyptic world, a family travels to safety while being pursued by teams of religious fanatics sent by the Brotherhood. In the mountains above Bishop, California, the Narrator and Rex (one of six children) fight off an attack of the Brotherhood. Then Lynn, the Narrator's daughter, is born. While leaving the area, seven year old Nancy appears and joins the group. She has been a slave of the Brotherhood, and her troubled behavior causes a host of problems. This extended family must use their brains, inner resources (psychic abilities) to outwit the Brotherhood, slavers, Mother Nature, and the bizarre behavior of Nancy to bring themselves to safety and Flagstaff, Arizona.
