Bretwalda — Philip Ketchum

'Twas the mightiest weapon the eyes of man had ever beheld; its mystic name meant “Ruler of Briton.” And from over the Northern Sea came a Viking's thrall -- the only man in the world who could wield that fearsome steel -- to save good King Alfred and the homeland he scarce remembered. Collecting -- for the first time -- all 12 stories of the Bretwalda saga. Volume #8 in The Argosy Library.
