Bretwalda (The Argosy Library‪)‬

’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.
