With the power gone, the UK falls into a state of panic. The ensuing anarchy is simply the warm-up act.

For dinosaurs, it was a big rock. For humans: Coronal Mass Ejection (CME). When the Earth is hit by the greatest CME in recorded history (several times larger than the Carrington Event of 1859), the combined societies of the planet's most developed nations struggle to adapt to a life thrust back into the Dark Ages. In the United States, the military scrambles to speed the nation's recovery on multiple fronts including putting down riots, establishing relief camps, delivering medical aid, and bringing communication and travel back on line. Just as a real foothold is established in retaking the skies (utilizing existing commercial aircraft supplemented by military resources and ground control systems), a mysterious virus takes hold of the population, spreading globally over the very flight routes that the survivors fought so hard to rebuild.

Ranger Quinn thought that morning would be like so many others. A hangover, a day off before going back to work keeping the lower levels of Zion City safe from itself. But a crime so horrific, so brutal in its execution, turns those mundane expectations around.

Before the lights went out, Jack Warrant never considered himself a prepper. That was someone on the edge, a conspiracy theorist or a doomsday cultist who had a fatalistic view of the world. He was neither a theorist nor a cultist. He was an optimist. At least that was what he told himself when the darker thoughts creeped into his psyche as he stared at the ceiling in the middle of the night. Whenever he started down the rabbit hole, he always clawed his way back into the sunlight.
