The Uncle Duncle chronicles: escape from Treasure Island

World-famous explorer Dunkirk Smiley is taking his nephew, Sage, on the vacation of a lifetime, using a magical talisman and flying in a World War II Supermarine Spitfire. But the aerial adventure goes awry when Sage’s imagination brings them to Robert Louis Stevenson’s Treasure Island. Together they must free a group of prisoners from the clutches of Long John Silver, lay claim to the glittering chests of pirate treasure, and fight for their very lives.
