Arthur Ransome's Swallows and Amazons series has stood the test of time. Ransome is not only a great storyteller, writing from first-hand experience, but each story celebrates eternally valuable qualities of practical knowledge, independence, and initiative. The twelve books are for children or grownups—anyone captivated by a world of sailing, adventure, and imagination.Here is the twelfth, and last Swallows and Amazons book published in Arthur Ransome’s lifetime. People familiar with the earlier titles will recognize the pattern: children set out on an adventure (this one off the coast of Scotland) with a minimum of parental advice and interference. Here, the story centers on a desperate race to thwart the efforts of pernicious egg collectors threatening the survival of a pair of rare birds not previously known to nest in British waters (actually, the bird is the handsome North American “Great Northern Diver,” more commonly called a loon).
