A Treacherous Trail. Nate King and his family are accustomed to dealing with the perils of the wild. It's the spread of civilization that sends them further into the rugged Rocky Mountains to find a more secluded home. Along the way, fighting off attacks from rattlesnakes and wild buffalo, Nate becomes separated from the rest of the group. And only then does he realize that civilization isn't so ready to be left behind. An old enemy has posted a $10,000 reward for the man who can kill the King family—and one group of vicious bounty hunters will stop at nothing to claim the prize.
