Rolfe, a young Norwegian boy, swore to carry out the one wish his father had expressed before his death at the hands of Blacks Sven Because an Irish woman had at one time aided him, he had asked his son to under take protection of an Irish woman at some time, as a debt of honor. So Rolfe and his young chieftain friend Lokar rescued Gwylla, a young Irish princess, who had been abducted. Rolfe did battle for the girl in Constantinople, Venice, and Kasbarg on the Rhine. And before the voyage ended Rolfe had foresworn his Norse gods for Christianity. This period recreation is excellent supplementary reading for boys and girls encountering Viking exploits in their social studies curriculum. A swashbuckling hero-tale.
