Great Northern?: Swallows and Amazons Series (Unabridged)

Finally! Here is the 12th, and final, book in Arthur Ransome's acclaimed Swallows and Amazons series. People familiar with his earlier work 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).
