A generation has passed since the Change that rendered technology inoperable around the world, and western Oregon has finally achieved a degree of peace. But a new threat has risen in Paradise Valley, Wyoming. A man known as the Prophet presides over the Church Universal and Triumphant, teaching his followers to continue God's work by destroying the remnants of technological civilization they encounter—and those who dare use them. Rudi Mackenzie, son and heir of the mystic Juniper, must journey with seven friends across a continent in chaos to the Sunrise Lands to solve the riddle of what destroyed a civilization. And as the friends journey farther into the interior, enemies may be within their own band as well as outside it.
