The laugher never comforts. It only reminds them that they're not alone. Kate and Nick have found safety behind the walls of Fort Vanguard, but peace is fragile in a world crawling with the dead. Each journey beyond the gates is a fight for survival, plagued by the Infected and survivors alike. When Kate is captured, Nick descends into madness. To find her, he'll carve through the wasteland, leaving pieces of his humanity behind with every kill. The dead are evolving. The living are losing themselves. And love might be the most dangerous disease of all.
