As the infected overrun what remains of civilisation, Amy and her father John fight to stay alive-and human-in a landscape ruled by Shufflers, Scavengers, and the ruthless factions who prey on the desperate. But when John is taken, Amy must face the wasteland once more with her friend Suzy, armed with nothing more than basic weapons and enhanced human abilities both women are only just beginning to understand they have a job to do. Their mission is simple: get justice, revenge, and find a cure for the A1 bacteria before there is no world left to save.
