An Old Captivity by Nevil Shute (Vintage 1968 Illustrated Hardcover)

Young pilot Donald Ross has little in common with the Oxford archaeologist who has employed him on an expedition to the Arctic – and still less with his beautiful but stubborn daughter, Alix. But once the three of them reach the treacherous shores of Greenland, in search of the ruins of early Viking settlements, their destinies are inextricably bound by the events that unfold there.
