Forbidden Fortune: The Legend of the Frenchman's Gold

Deadly Price of Fortune
In a small town in Montana, near the Blackfoot River, local legends tell of Louis Mattour, a French quartermaster for the Lewis and Clark expedition who secretly traded with Indians for gold and hid his treasure in a cave along the river before vanishing without a trace. No one knows what happened to the Frenchman, but his legend has survived the centuries.
Fortune hunters tried for years but failed to locate the gold in the treacherous river caves, until three young boys tragically disappeared in the late 1950s. Decades later, a mysterious young man, armed with the long-lost secret to the cave, arrives to solve the mystery and claim the fortune for himself. His clandestine exploits ignite a sinister plot to destroy decades-old evidence of wrongdoing and create new dangers for curious young adventurers Bo and Ryan Benbright and their friend, Bret.
Will the dangerous caves claim more young victims? Will the Benbright family face the same anguish as others before them? Or will the small town unite and save its real treasure?
