London is doomed and Scotland may be their only chance for survival.

If the vines and the Creeps didn't bring about London's ultimate destruction, Operation Inferno would. Within six days, thermo baric bombs will be dropping on the city, obliterating everything. Adam Blake has no choice but to lead the inhabitants of the Block out of the city and through a hostile world devoid of human life. Their only chance of safety lays over five hundred miles away in the cold wilds of Scotland.

As they put distance between them and the impeding bombing, Adam fears failure the most. With his past experience and losses weighing him down, he struggles with the ability to get this motley crew to safety. It's a long and dangerous road leading north - Hell's Road - with his new family and what's left of the survivors he's grown to know. Stakes are high in his newfound apocalyptic life.

Can they get far enough away from the blast zone? Will they be able to stand on their own against the vines, Creeps, and whatever else they might face on Hell's Road?
