Thomas loved his summer visits to his grandmother's on Cape Cod. He spent hours wondering about the sailing ships of the past and imagining their stories. He dreamed of being on a sailing ship himself. One afternoon after a night of terrible thunderstorms, Thomas finds, deep in the sand, a weathered, old-fashioned belt buckle. When he picks it up, a boy his own age, Silas Rich, who was a cabin boy on a ship called the Monomoy that sailed almost 250 years ago, appears. Suddenly the world of sailing ships is very near as Silas tells his tale.
