The Living — David Kazzie

The stand-alone sequel to David Kazzie's bestselling IMMUNE series… Thirteen years have passed since the Medusa plague wiped out nearly 99 percent of the world's population and pushed humanity to the brink of extinction. Climate change triggered by nuclear skirmishes in the last fevered days of civilization decimated agriculture and livestock, and the hardened survivors battle for what few resources remain. Rachel Fisher is one of the lucky ones. In her small community in Nebraska, she and her family have access to food, clean water, weapons, and medical care. And her 11-year-old son Will is the only child known to have survived infancy since the plague. But everything changes when someone comes looking for him.
