One windswept winter's evening, Arden Tregorey listens, enthralled, as his father tells him of his "golden secret" and of how he once outwitted the notorious one-eared pirate Lambert "Luggole" Spain. The next day his father is kidnapped and disappears, so young Arden sets off to the Caribbean in search of him. How will he travel the 5,000 miles of dangerous Atlantic Ocean, and will he succeed in finding his only living relative?
