Thaddeus Bix and the Pirates of Pepperjack

Captain Pepperjack of the Black Wyddah pirate ship has mysteriously disappeared, and the pirates of Pepperjack are desperate to get him back.
Thaddeus Bix is astonished to be kidnapped by four smelly pirates, thrown into a sack, carried aboard the Black Wyddah and imprisoned in a magical sea chest. All because he has something that the pirates don't.
Will Thaddeus succeed in escaping from Captain Pepperjack and his rabble of pirates? Or will he remain a prisoner forever?
