Synopsis: "He's homeless. He's on the run. And he wants revenge. Marcus Battle has left behind his home. Now he's on a seemingly impossible mission to find a missing child. But can he balance that responsibility with his deep, primal desire to exact revenge on the men who destroyed his solitary existence? The world he discovers on his journey isn't the one he remembers before a pneumonic plague called The Scourge killed two-thirds of the world's population. It is lawless, depraved, and far-deadlier than the disease which created it. Battle made a promise to find that child. It's a promise he regrets more acutely with every step of the journey where he is as much the hunter as he is the hunted." — quoted from this book's product page on Amazon as of 2018-06-12.
