Wall (The Traveler, #3)

HE SURVIVED THE SCOURGE. HE ESCAPED THE CARTEL. NOW HE FACES THE WALL.
In the chaos of a global plague, evil took hold. Governments fell, the good became servants, and the Cartel rose to power. A wall was built to contain the wasteland and keep the evil at bay. Now an organized resistance wants change. They're willing to fight for it and they've asked Marcus Battle to help. The last thing Battle wants is another war. But if that's what it takes to gain freedom and safe passage to the other side of the wall, he'll take aim and fire.
