When Frank and Joe find a young woman washed up on the beach of the Caribbean’s St. Lucia Island, they realize there’s trouble in paradise. Who is the mystery woman? What is she hiding? The answers lie offshore, where a ship’s crew scavenges for pirate gold. But in the face of spearguns and man-eating sharks, the Hardys discover that the sea hides more than gold.
Franklin W. Dixon is the author of the ever-popular Hardy Boys books.
