(Book 1.) The dead have risen, and they're hungry. Consumed with a ravenous desire for human flesh, they are everywhere. All they do is kill, and the people they kill? Moments later, they get up and start killing themselves, infected with whatever it is that is causing the newly dead to rise. Society is crumbling. The world is going straight to hell. Your own family and friends may have joined the ranks of the undead. And they're coming right at you. When 21-year-old Ashley Ziegler finds out she is immune to the epidemic, she sets off to survive it. And maybe help some others along the way.
