Great Northern? by Arthur Ransome is a captivating addition to his beloved "Swallows and Amazons" series, though it stands distinctively as a tale of ornithological adventure and ethical dilemmas. The story sees the Walker children and their friends embarking on a sailing holiday in the Outer Hebrides. Their idyllic exploration takes a dramatic turn when they discover a nesting pair of Great Northern Divers (loons), a rare and protected species. The children's excitement soon turns to a moral quandary as they encounter an unscrupulous egg collector determined to steal the eggs.
