He doesn't remember the days before the sickness. He only knows the world since it went bad. The empty towns. The rusted-out cars. The corpses, everywhere. He doesn't know why he rides the rails. He just does. The trains never take him away from the ruin. The trains never take him anywhere. Until one day they carry him to a little town called Black Hole, Kentucky, and he meets a strange woman who knows him. Who knows everything.
