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. An investigation into the death of a senior leader in their underground utopia safe from the harsh radioactive wastelands beyond their walls forces Quinn beyond that safety and into the world outside.

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.

This omnibus edition contains Survival (book 1) and Humanity (book 2) of the After It Happened series.

A survivor of undead suburbia, mountain man Augustus “Gus” Berry is extremely careful when it comes to his actions and movements. He takes no chances and painstakingly weighs every decision—until he sets out for the hospital at the edge of town, hoping to discover a treasure trove of essential supplies. Soon, Gus will experience terror the likes of which he's never encountered before . . .

Cassie Forrest isn't surprised to learn that the day she’s decided to get her life together is also the day the world ends. After all, she’s been on a self-imposed losing streak since her survivalist parents died: she’s stopped painting, broken off her engagement to Adrian and dated a real jerk. Rectifying her mistakes has to wait, however, because Cassie and her friends have just enough time to escape Brooklyn for her parents’ cabin before Bornavirus LX turns them into zombies, too.
