From USA Today bestselling author Nicholas Sansbury Smith comes another harrowing story of survival in a post-apocalyptic world. 

The end of the world is just the beginning of the hunt…
Estes Park Police Chief Marcus Colton and tracker Sam ‘Raven’ Spears have never liked one another, but when a young girl goes missing in Rocky Mountain National Park, Colton hires Spears to help find her. Their search ends after a night of devastating horror. When word reaches Estes that the nation has been hit by a coordinated electromagnetic pulse attack, Colton and Spears are forced to work together again. But they quickly realize they aren’t just tracking a killer–they are tracking a madman. As the United States descends into chaos, the hunters become the hunted.
Halfway across the country, Senator Charlize Montgomery pulls back her drapes to see the nation’s capital has gone dark. Forced to set off on foot, she treks across a city that has woken to a new world, and as the night progresses, she learns the EMP attack was just the beginning…

The worst of nature and the worst of science will bring the human race to the brink of extinction…

Master Sergeant Reed Beckham has led his Delta Force Team, code-named Ghost, through every kind of hell imaginable and never lost a man. When a top secret Medical Corps research facility goes dark, Team Ghost is called in to face their deadliest enemy yet–a variant strain of Ebola that turns men into monsters.


Now a USA Today bestseller and An Audible Editor’s Pick of 2016 and An Audible Best of 2016 in Science Fiction.

From the bestselling author that brought you the award-winning Extinction Cycle series, comes an all new vision of the apocalypse and the future of humanity.

More than two centuries after World War III poisoned the planet, the final bastion of humanity lives on massive airships circling the globe in search for a habitable area to call home. Aging and outdated, most of the ships plummeted back to earth long ago. The only thing keeping the two surviving lifeboats in the sky are Hell Divers: men and women who risk their lives by diving to the surface to scavenge for parts the ships desperately need.

When one of the remaining airships is damaged in an electrical storm, a Hell Diver team is deployed to a hostile zone called Hades. But there’s something down there that’s far worse than the mutated creatures discovered on dives in the past—something that threatens the fragile future of humanity.
