A novel centered about the National Park of Mount Desert, Maine, this story of teen-age Ira, a summer visitor, and Ellen, a year-rounder, introduces the reader to one of this country's most beautiful sites. Ellen and Ira share a love of this misty island of granite and forest. Their interest in its past--its Huguenot, Viking, Jesuit, Basque, and Indian heritage--and its present--an annual pageant, the lobster and fishing trade, its vacation attractions--bind them together in an enduring affection. This story of a summer in their lives, Ira's scholastic difficulties, the pursuit of a war time spy-ring, deftly interwoven with the theme of conservation, and brightened by the antics of a pet seal, is both entertaining and factually illuminating. There is more here than an academic spooning of facts: Beckoning Landfall embraces the very sound and touch of Mount Desert.
