Gwendolyn must protect her people as she finds King's Court under siege. Behind the McClouds lie the threat of Romulus and his dragons, who, with the Shield destroyed, embark on a catastrophic invasion. Gwen must fight for survival of herself, for her baby, and for her people-amidst an epic battle of dragons, and of men. Thor, meanwhile, embarks on the quest of his life in the Land of the Druids, trekking across a fearsome and magical land, a land unlike any other, with magical rules out of its own.
