Nomad Found: A Kurtherian Gambit Series (Terry Henry Walton Chronicles Book 1) by Craig Martelle and Michael Anderle

Armageddon. The end of the modern world. Many saved themselves. Others tried to save what was left. Most failed.
Colonel Terry Henry became the Nomad and disappeared.
After twenty years, he returned. It was time to drag humanity back to civilization.
The first woman he meets offers him water. Maybe there is hope. But then the refuse of humanity comes to take it away. Terry delivers the brutal justice this new world understands.

Terry had lost everything and thought there was nothing left to live for – until now. His mission is nothing less than saving the world from itself.

Terry won’t rest until justice is served.

Join the Nomad in his journey across the wasteland that used to be America.
