It didn t take long for the world to die. And it didn t take long, either, for the dead to rise. Born on the day everything ended, a world filled with the walking dead is the only one that Aaron knows. Kept in seclusion, his family teaches him the basics. How to read and write. How to survive. Then Aaron makes a shocking discovery. The undead, who desire nothing but flesh, ignore him. It s as if he s invisible to them. The survivors of the old suburb of Lexington call a high school their home. They live day to day, without any of the luxuries mankind used to enjoy. Samantha is a product of the new world. Alone, cold, looking out only for herself. She and the other residents of Lexington feel their hope dwindling. They need change. They need someone who can face the corpses. They need someone who can live in a city of the dead. They need Aaron.
