With Nora away on a vitally important mission in Annwn, Jack Brenin has to take sole responsibility for rescuing the last two Dragonettes left on earth from being roasted for a Spriggan feast. Using his trusty Book of Shadows for guidance, and with his friends Camelin the raven and Timmery the bat (along with a cunningly captured Dorysk), Jack mounts a daring raid on the Spriggan stronghold inside Silver Hill.
But his triumphant return is overshadowed by the discovery of a problem in Annwn that is too big for even Nora's magic. Can Jack help the Blessed Council to rescue the sleeping Druids?
