Months have passed since Mystere left England in search of Joyeuse, leaving Douglas and Margaret behind, safe in behind ancient shields in a manor house in Sussex. Then Douglas is called away for an emergency, and disappears without a trace. A letter arrives, assuring Margaret that Douglas will be safe. A letter from Caedda, one embedded with spells meant to kill. Fearing for her husband, Margaret risks her own life and that of her child in a desperate attempt to summon Mystere, setting into motion a journey that will take them from Sussex to Aachen to the mountains of Austria, and to the long-hidden sword, Joyeuse. With all four swords once more in the world, the secrets they've been hiding will finally be revealed.
