Flora Mackie was twelve when she first crossed the Arctic Circle on her father's whaling ship. Now she is returning to the frozen seas as head of her own expedition of exploration.

Jakob de Beyn was raised in Manhattan but his yearning for new horizons leads him to the Arctic as part of a rival expedition. When he and Flora meet there is an instant connection that slowly builds to become an all-consuming love. The affair survives the growing tensions between the two groups. Then, after one last glorious summer on the Greenland coast, Jakob joins his leader on an extended trip into the interior, with devastating results.

The stark beauty of the Arctic, where pack ice can crush a ship like an eggshell, and the empty sweep of the tundra, alternately a snow-muffled wasteland and an unexpectedly gentle meadow, are vividly evoked. Against this backdrop Stef Penney weaves an irresistible love story, a compelling look at the dark side of the golden age of exploration, and a mystery that Flora, returning one last time to the North Pole as an old woman, will finally lay to rest.
