This book follows the adventures of the five Walker children after their parents leave them on a "desert island" with provisions for a long stay - and a blank map to fill in.
It all started with a coot's nest. Dorothy and Dick meet Tom Dodgeon, Port and Starboard, and three pirate salvagers all members of the Coot Club Bird Protection Society. When one of the coot's nests is disturbed by a shipful of Hullabaloos-rude holiday boaters - trouble begins. Frantic chases, calamitous boat collisions, and near drownings fill the pages of this exciting fifth addition to Ransome's classic children's series.
