It's November 2022. The human race has been wiped out by the 6DM virus (Six Days Maximum - the longest you've got before your organs disintegrate and you melt from the inside out). The end of the world as we know it. Yet someone is still alive. Alone in a new world of burning cities, rotting corpses and ravenous rats, one woman has survived. A woman who has spent her whole life compromising what she wants and hiding how she feels to meet other people's expectations. But with no one else left, who will she become now that she's completely alone?

Britain is awash, the sea creeps into the land, brambles and forest swamp derelict towns. Food production has moved overseas and people are forced to move to the cities for work. The countryside is empty. A chorus, the herd voice of feral cows, wander this newly wild land watching over changing times, speaking with love and exasperation. Jesse and his puppy Mister Maliks roam the woods until his family are forced to leave for London. 

It's 1962, and physics student Grace Pulansky believes she has met the man of her dreams, Robert Jones, while serving up slices of pecan pie at the local diner. But then the FBI shows up, with their fedoras and off-the-rack business suits, and accuses him of being a bomb-planting mass-murderer. Finding herself on the run with Jones across America's Southwest, the discoveries awaiting Gracie will undermine everything she knows about the universe.

Prosecutor Justine Boucher has only asked for the death penalty once, in a brutal murder case. In doing so, she put her own life on the line. Because, if the convicted are later found innocent, the lawyer who requested the execution will be sentenced to death. Justine had no doubt that the man she sent to the chair was guilty. Until now. Presented with evidence that could prove his innocence, Justine must find out the truth before anyone else does. Her life depends on it.

Angela is a woman trying to get by in this bewildering new world. Though she still lives with her husband and children, they lead separate lives. Confined to their rooms, they communicate via their computers and phones. In some ways, very little has changed. That is, until she spots a mysterious stranger walking through town without even a face mask for protection. A man, it seems, immune to this disease. A man unlike anyone else she knows. A man it might just be safe to touch....
