Counties:. 1, #1

Fifty years after the Great Flash tore the world apart, humanity's remnants cling to life in the claustrophobic depths of the London Underground. The surface is a radioactive wasteland, choked by mutated flora and stalked by unnatural predators. Below ground, the survivors have fractured into isolated, self-governing factions known as the "Counties". Life in the tunnels is a relentless cycle of rationing, repair, and desperation.
Sam is a 'Ghost'-a scavenger from King's Cross whose survival instincts have been honed in the most unstable and irradiated 'Red Zones'. His perilous missions are the only thing keeping his community's failing infrastructure alive. But during a desperate dive for critical components, Sam unearths something far more dangerous than mutated beasts or radiation: a pre-Flash data reader containing a colossal, generational lie.
The surface is not entirely dead. Safe zones exist. The atmosphere is recovering. Armed with knowledge that shatters the very foundations of their subterranean existence, Sam is thrust into a deadly game of power and deception. The ruling Council of the Rails will do anything to maintain their iron grip on the dark, and whispering factions in Waterloo, Whitechapel, and Westminster are ready to wage a brutal underground war for control.
