The Shield Ring

High in the mountains of the Lake District is a secret valley where the Vikings have their last stronghold--their Shield Ring. The Normans seek to crush this group of Northmen and to bring all of England under their control. They build a castle in Carlisle and send an army north. Meanwhile, the Northmen lamb and harvest as though life were normal, but Ari Knudson sharpens Wave-flame and the Jarl prepares his War Host. Two youths of the village--Frytha, a Saxon girl who fled to the valley when the Normans burned her home, and Bjorn, the foster-son of the old harper--make ready, too. As the Norman's approach the secret valley, the Northmen recruit able bodies, and Bjorn volunteers to enter the Norman camp as a spy. Frytha knows Bjorn's deepest fear: that if he is captured, he will fall to Norman torture and reveal the location of the Shield Ring.
