The Deadly Trap — Jan Burchett; Sara Vogler

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!

There's a new pirate aboard the Sea Wolf and he's popular with the crew, but Sam is suspicious - why is the new recruit so interested in Captain Blade? And how can Sam convince his friends that they're falling into a deadly trap?
