A combination of mystery and action/adventure entitled Lawless Moon, continues the quest for Blackbeard’s fabled hidden loot. Ted Rideen, a geologist who rebuilds beaches, unwittingly stumbles onto a clue to another of the pirate’s vessels that sank in the same storm that took the Queen Anne’s Revenge to the sea floor. The clue, an ornate ring still attached to a fossilized finger, leads Ted and his crew on a deadly chase to locate Blackbeard’s lost treasure hoard, while at the same time jeopardizing both his marriage and his fledgling business.
