A Viking Maiden for the Marquess by Michelle Willingham

Eric Fielding, the Marquess of Thorgraham, is shipwrecked upon the shores of Norway during a violent storm and brought back a thousand years in time. He finds a beautiful Viking maiden waiting for him, but Katarina Larsdottir needs a warrior to slay her enemies—not an English gentleman.
Katarina is fascinated by the man who returns to her. He looks similar to Arik Thorgrim, the man she has loved all her life…but the handsome stranger is nothing at all like the fierce warrior she remembers. His kindness soothes the wounded scars of her past, awakening her to a passion she has never known.

But when an enemy from Katarina’s past threatens to kill everyone she loves, Eric must cast off the civilized rules of his upbringing and fight for her…or lose everything.
