Voyage of slaves - Brian Jacques

Ben and his Labrador Ned, castaways of the Flying Dutchman, are destined to roam the earth across the centuries, never stopping in one place and never growing a single day older. Now adrift in the Mediterranean sea, the boy and his dog fall into the clutches of the Barbary Slave Lord, Al Misurata. And so begins a roaring adventure,, from the Libyan coast to the Italian border during which they gain good friends and encounter ruthless enemies in their quest for freedom. A sequel to The Castaways of the Flying Dutchman and The Angel's Command, these thrilling adventures are based on the legend of The Flying Dutchman ghost ship and its mad sea captain, cursed to sail the seas for all eternity.
