Young Kindan has no expectations other than joining his father in the mines of Camp Natalon. Fortunately, the camp has a watch-wher, a creature distantly related to dragons and uniquely suited to specialized work in the dark, cold mineshafts. Kindan's father is the watch-wher's handler, and his son sometimes helps him out. Then disaster strikes. In one terrible instant, Kindan loses his family and the camp loses its watch-wher. Fathers are replaced by sons in the mine - except for Kindan, who is taken in by the camp's new Harper. Grieving, Kindan finds a measure of solace in a burgeoning musical talent and in a new friendship with Nuella, a mysterious girl no one seems to know exists. It is Nuella who assists Kindan when he is selected to hatch and train a new watch-wher, a job that forces him to give up his dream of becoming a Harper; and it is Nuella who helps him give new meaning to his life. Meanwhile, sparked by the tragedy, long-simmering tensions are dividing the camp. Far below the surface, a group of resentful miners hides a deadly secret.
