The Moon of Gomrath is the one night of the year when the Old Magic is at its most powerful. Had Colin and Susan known this, they would have never lit a fire on the landmark known as the Beacon. But now no one is safe--the horsemen called the Wild Hunt are awake and on the ride. There will be a battle, and the outcome will depend on three unlikely champions: Susan, Colin, and their ally, the wizard Cadellin. Includes an afterword by the author.
