A college girl's summer devoted to arctic natural history is a bright-eyed report of the world around Churchill, the northernmost Canadian point on the west coast of Hudson's Bay. She explores the teeming tundra, hunts plants and birds with a camera, goes on unscheduled trips and expeditions, contrasts Horace, back home in Boston, with the man she meets in this big new world, discovers what a vast change the subarctic is from her protected, conventional home life. The naivete to the italicized style makes the reader too, find the tundra ""awfully thrilling"".
