A Meeting at Corvallis
In the tenth year of The Change, the survivors in western Oregon have learned how to live in a world without technology. But a confrontation between the forces of those who would rebuild the world peacefully and the feared Protector, who will use whatever means at his command to extend his power, threatens to plunge the entire region into open warfare.
