The world is dead, devoured by a plague of reanimated corpses. Cahz and his squad of veteran soldiers are tasked with flying into abandoned cities and retrieving zombies for scientific study. Deep in infected territory, hundreds of miles from their support vessel, the ever present dangers weigh heavily on Cahz's mind as he shepherds his team to make quick, clean extractions. Then the unbelievable happens. After years of encountering nothing but the undead, the team discovers a handful of disheveled survivors in a fortified warehouse with dwindling supplies. Surrounded by hordes of ravenous corpses, Cahz is faced with the terrible responsibility of determining the five passengers who will escape in the helicopter. While those left stranded must continue to fight off the infected and starvation long enough to be rescued.

The world is infected. The dead are reanimating and attacking the living. In a city being overrun with ravenous corpses people find safety where they can. A disparate group of strangers drawn together by chance seek sanctuary from the carnage outside in an empty office block. Besieged by an army of walking dead and with little hope of rescue the group must learn to work together if they are going to survive. But for how long can the barricades hold back the ever increasing hordes of undead? How long before the food runs out? How long before those who were bitten succumb to the infection? And how long before they realise that the dead outside are the least of their fears?

The world is dead, devoured by a plague of reanimated corpses. In a crumbling city, Sarah, Nathan, and a band of survivors barricade themselves inside a warehouse surrounded by a sea of shambling putrefaction. Days in seclusion blur by, and their food is nearly gone. The group is faced with two possible deaths: creeping starvation, or the undead outside the warehouse. As Sarah stands on the edge of the warehouse roof preparing to step out into oblivion she spots a glimmer of hope. In the distance a helicopter approaches the city... but is it the salvation the survivors have been waiting for? And do they dare attempt to fight their way through the mass of infected dead to reach it? BONUS AUDIO: Includes an exclusive introduction by the author.
