Capturing a crucial moment in the history of exploration--the mid-nineteenth century romance with the Arctic--Andrea Barrett's compelling novel tells the story of a fateful expedition. Through the eyes of the ship's scholar-naturalist, Erasmus Darwin Wells, we encounter the Narwhal's crew, its commander, and the far-north culture of the Esquimaux. In counterpoint, we meet the women left behind in Philadelphia, explorers only in imagination. Together, those who travel and those who stay weave a web of myth and mystery, finally discovering what they had not sought, the secrets of their own hearts.
