Penguin Summer, first published in 1960, recounts the husband and wife expedition to the Falkland Islands in the 1950s to study the penguins and other birds found on these harsh, isolated islands in the south Atlantic. In addition to a description of the birds and their habits, author Eleanor Pettingill describes her and spouse Sewall Pettingill's adventures on the islands and the life of the hardy islanders, all told in an engaging, likable style. Included are 54 pages of maps and photographs.
