Query: A must have for the series collector

If you collect the Swallows and Amazons series, you simply must have this book in your collection. If, on the other hand, you are just someone looking for a good book, well...this is a GREAT book. It is a classic that both children and adults will love and enjoy many times over.Arthur Ransome is one of the greatest authors ever to live, and his books reflect that fact.
