Zombies. It is seven months since the outbreak. The world is in ruins. Britain is a radioactive wasteland peopled by the undead. The few survivors cling to the hope that they might wake up tomorrow. For most, that is all they have left. But Nilda has something more, the chance that her son is alive.

The outbreak began in February. Nations went to war. Governments collapsed. Billions died in the chaos and anarchy that followed. Billions more were infected. They died. They came back. It is now October. Out of the tens of millions who lived in southern England, only 90 people remain. They sought sanctuary behind the ancient walls of the Tower of London, but it was only a temporary refuge. There is no more food to be scavenged from the ruins of the old world. Their water supply is polluted.

Eight months after the outbreak, Bill Wright is trapped in Ireland. Surrounded by the undead, low on food and lower on water, he's been in this situation before. Unlike before, help is only a rifle-shot away. While waiting for the rescue he is sure will come, he records the turbulent events since his last entry.

There are no reported outbreaks in the UK or Ireland. That's what the government broadcasted. Nilda didn't believe it. Not trusting the authorities, she, and her son, Jay, stay behind when Penrith is evacuated. After weeks of rationing, there is little food left in the small town and many other survivors competing for it. Choosing diplomacy over violence, she attempts to forge a community out of a disparate group. As zombies gather outside their walls, she realizes that they will have to seek sanctuary elsewhere.

Within hours of the first outbreak, Manhattan was overrun by the living dead. Within a few days, the undead had reached every corner of the globe. There was no evacuation of Northern Ireland, and no quarantine in the Republic. A naval blockade prevented ships from docking, but they didn't prevent those who could reach the coast from fleeing by sea. Those who were left behind took refuge in castles, police stations, churches, military bases, and any other buildings with strong walls.

Three months after escaping from London, Bill discovers the true extent of the global war that followed the outbreak. Most of the world has been destroyed, but though ruined farmland and abandoned cities are filled with zombies, there are other survivors and there is a safe haven - so he is told - in a small village on the Irish coast.

Anglesey has become home to nearly ten thousand survivors from across the Atlantic. While there is still danger from the undead on the mainland, there is hope. Hope that the zombies might die, hope that the electricity supply might be restored, and hope that more survivors will be found. Hope is not enough. Sergeant Branofski and Chester Carson venture into northern Wales to set up a network of safe houses that will provide a route to Anglesey for those still trapped in the wasteland. Though they find survivors, they discover something far worse.

Billions died during the global civil war that followed the outbreak. Anarchy took grip. Chaos ruled. The world collapsed. In Britain, the evacuation failed. Nowhere was safe from the undead. Four months after the outbreak Bill Wright has found safety in a ruined abbey in southern England, but he is still alone. All he has for company are the files sent to him by his shadowy contact, Sholto. On those, he believes he has found the origins of the undead.

Anglesey became a refuge for survivors from across the world, but living in the shadow of a decrepit nuclear power station was always a precarious existence. There is only one destination for their final exodus from Britain, but Belfast won't become their new home. There are fewer undead on the island of Ireland, but they still number in the millions. With farming impossible, with the weather worsening, with ammunition exhausted, desperation turns to despair. All seems bleak, but the survivors are unaware how desperate their situation truly is. 

After the outbreak came the nuclear war. The blasts killed millions. Chaos followed. Most of those unlucky enough not to succumb to starvation and disease joined the ranks of the living dead. Fleeing the impossible nightmare, 10,000 from nations across the Atlantic seaboard found refuge on the Welsh island of Anglesey. There, they should have been safe. There, they should have been able to rebuild. There, they were betrayed.

The outbreak was in February. By the end of November, Earth has become a hellish wasteland ravaged by the undead. Survivors from across the Atlantic seaboard took refuge on the Welsh island of Anglesey. Beset by dangers from within, they departed to establish a new refuge in Belfast. Not all of them arrived. Six took the last plane on its last flight but crashed in France. Expecting a sprinting battle through the ruins of Belfast, they packed light. Their chances of survival are slim. There was no evacuation in France. No quarantine. No rationing. But there are zombies.

Northern France is a frozen morass of mud and snow across which rampages a horde of the undead, a hundred million strong. That won’t stop Chester Carson and his comrades. Seeking a way across the Channel, they make for the coast, unaware that Britain has been abandoned, Belfast is a ruin, and that radiation is seeping into the Irish Sea. If they knew, that wouldn’t stop them either. They’re on a quest to save their family, their friends, and humanity itself; failure is not an option.  

Once, it was home to half a billion people. A year after the nuclear war, Europe is a radioactive, storm-ravaged wasteland through which a hundred million undead inexorably march. In their wake, they leave nothing but ruins. Ahead of them flee those few who managed to survive this long. Chasing them are the dregs of humanity. Once known as the Rosewood Cartel, they kill, loot, and destroy as indiscriminately as the living dead.

Tom Clemens has been living in the shadows for years, searching for those responsible for the death of his family. Framed for murder, he is on the run when the first outbreak occurs. With thousands of others, he fights his way out of New York, and joins the exodus searching for a safe refuge in America. On that journey he learns the identity of those responsible for the betrayal of the species, and of a scientist who might be able to stop the living dead. So begins his quest to save humanity.

It is a week since the outbreak began in New York. The president has been betrayed. The vice-president is dead. The conspirators are close to victory. Having narrowly escaped agents of the cabal, Tom Clemens heads to Washington in the hope of warning the president, but it is too late. The highways are impassable, filled with millions fleeing from the cities. As refugees storm the towns, and zombies fill the smoking ruins, survivors become more deadly a threat than the impossibly living dead.
