This is a book about a long, difficult flight. The story follows an air expedition to Greenland in search of the ruins of Viking settlements. It mixes the modern story of
Ross (a pilot) Cyril Lockwood (an Oxford archaeologist), and his daughter Alix with the "remembered" story of Haki and Hekja, two runners from Scotland who
sailed with Leif Erickson to Vinland the Good, the first European explorers of America.
