Be careful what you wish for . . . When Viking Nils Bjornsson turns his back on Valhalla to find his chieftain's stolen knife and erase the dishonor brought upon Nils's family, he appeals to the Norse gods to send him a handmaiden to help him fulfill his pledge. He should have remembered how the old gods like to meddle in the lives of mortals. Lady Linnea Sutherland knows her father wishes her to marry their neighbor, Lord Tuthill. It is the perfect match for a Regency miss. But Linnea is looking for a hero, a man who excites her heart as boring Lord Tuthill does not. When she discovers Nils injured on the shore, she gets caught up in helping this handsome, dangerous man complete the vow he made nearly a millennium before. But first she must teach this Viking how to act like a Regency gentleman. To help Nils means that Linnea must dare the ancient ways of his past and risk her future. In a game played in the hall of Asgard, two human hearts are of little consequence, and love can become a blessing . . . or the ultimate weakness.
