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).
