How to become an Undercover Pirate...1)Have a pirate captain as your ancient ancestor 2)Find a message in a bottle and a magic gold doubloon 3)Get whisked back in time to join a pirate crew 4)When you get home DON'T TELL ANYONE. Remember - you're undercover! Sam Silver lives near the sea and enjoys beach-combing for pirate treasures. When he finds an ancient message in a bottle he thinks it will make a great new relic for his collection, but the bottle holds a very special secret...Inside is a gold doubloon which whisks Jack back in time to 1705. Suddenly he's on board a pirate ship - the Sea Wolf - surrounded by her fearsome captain and crew and sailing the Caribbean Sea. If Sam can't think of a very good reason why they should keep him alive, he'll be forced to walk the plank! Ages 7+.
