Seekers

Jack survived the Takers at the Battle at the Buffalo Jump, but at great sacrifice that cost a man his life. Now, Jack, along with his motley crew of companions, are headed back to Eden, Texas, seeking the whereabouts of his father.
Along the way they encounter other survivors; some friendly, some decidedly unfriendly. And they encounter more Takers.
Lots more takers.
But nothing can prepare them for what they will find when they follow instructions to go to Cheyenne Mountain in Colorado.
This time, it will be a miracle if anyone survives.
