The Vagrant, book 1
Peter Newman2015

The Vagrant is his name. He has no other. Friendless and alone he walks across a desolate, war-torn landscape, carrying nothing but a kit-bag, a legendary sword and a baby. His purpose is to reach the Shining City, last bastion of the human race, and deliver the sword, the only weapon that may make a difference in the ongoing war. But the Shining City is far away and the world is a very dangerous place.
