Naval Commander Walker, with the complete cooperation of his wife, their mother, maroons his five children on a tidal island on the coast of England. Of course, the children, ranging from the eldest, John, to the youngest, Bridget, are even more enthusiastic than their parents. It's summer vacation time again and the family is looking forward to a time camping and exploring the island. Then Commander Walker's bosses, the Lords of the Admiralty, decree his presence is required in London. All is gloom until Walker persuades his wife that these kids have demonstrated their responsibility and can be left alone for a time.
This is the eighth in an excellent sailing/adventure/camping series from this author. Like the others, Secret Water, is a careful chronicle of the Walker children's adventures. Along the way readers are treated to practical advice about camping, sailing, and dealing with tides and mud. This book also introduces new characters and reunites the Swallows and The Amazons. All of it is impeccably written with style, verve, great pace, a mystery or two and the sensitivity of the author to the attitudes and perceptions of children of various ages. This is a book that can be read by children of every age.
A bonus is the large number of pen and ink illustrations, done by the author.
