A mysterious, famed sword. An ancient prophecy. And an inevitable battle.

Join the Noland kids in this intense, page-turning, Hardy Boys meets Journey to the Center of the Earth, faith-based mystery/adventure.

In search of their father, the Noland kids travel to Vietnam's famous Phang Nha cave system but find themselves in a whole new world vastly different from their own and on the brink of disaster.

Enmeshed in a deep history of distrust and feud, three tribal leaders guard their land, traditions, and possessions with a jealous eye and a misplaced focus. But can the Nolands shine truth in this maze of dark, twisted lies and find a way out before these primitive civilizations self-destruct?
