Ten years after nuclear war devastates Britain, Lazarus and his adoptive siblings are flesh and blood to each other; to their victims, they are ruthless killers who should exist only in nightmares. Now their next target, a group of men seemingly made soft by a decade of hiding in underground bunkers, welcome the upcoming attack because they are far from weak. Armed and prepared, they are ready for Lazarus and his family. After the ensuing violence, lost and alone, Lazarus is desperate to make it through the irradiated wasteland to his clan before their captors reach a new government forming in Dover. Armed only with his axe, Lazarus will stop at nothing to kill the men who would dare threaten his kin. But, unknown to either side, a terrible secret waits far below Dover Castle, lost for decades in the silent labyrinth of wartime tunnels. A secret infinitely more dangerous than any killer!

In the ultimate battle between evil and evil...only one can win.
Four hundred years ago, Benjamin Harwood butchered whoever he saw fit to kill, knowing that sacrificing his murder victims to a demon would keep him safe from eternal punishment. But now, their agreement has been torn in half and the demon is coming for Harwood’s soul, coming to set him to burn.
Preparing for war, Harwood gathers the worst of the worst, the monsters and murderers he calls friends.
With this group of damned killers, Harwood must return to the crimes of his past and seek help from his most recent prey: a teenage girl whose family he destroyed, a girl with more reason to loathe him than anyone in his life or death. Only then he can try for a redemption that may be impossible or face a universe of suffering. But Harwood doesn’t know there is a hole in the floor of the world.
And something much worse than the dead is down there....

If Nicola is to have any chance of finding her family and if Cate is to escape from the siege, they must reunite and then descend into the belly of the ruined hospital where the horrific truth of what truly connects the two women is waiting for them. Waiting for them down in the dead room.
