For young Lexi Broadmoor and her younger brother Travis, the detonation not only took their father away, but their future as well. Now stranded on a highway far from home without any survival skills or someone to protect them, staying alive will depend on their wits, a single bug-out bag, and a map to a stranger’s house.

It really is the four horsemen of the apocalypse, Death, Famine, War, and Conquest. Things a seventeen-year-old boy shouldn’t have to deal with. In those most infamous words, mistakes were made. It wasn’t supposed to happen. The asteroid was supposed to miss. Running for their lives, Ryan Conrad and Kelsey Morgan, race to escape the impact of a super asteroid and the apocalyptic world it left behind. Fighting to survive the aftershocks. The earthquake to end all earthquakes, the largest tsunami in human history, and worst of all, the EMP and loss of civilization.

As earthquakes are triggered, fault lines split, buildings crumble, and monstrous tsunamis rush inland, Jax, his daughter Zoe, and a group of civilians with vastly separate lives collide in the Northwest in an interweaving story of survival, loss, and redemption. Meanwhile, Natalie Reid is at the Gatlinburg Midnight Parade, charged with caring for teens from a group home; when the earth shakes, the sky lights up in a brilliant light, and planes fall from the sky.

Clint Redshaw walks into a port facility meeting expecting an ordinary day arguing about the budget. When the shaking starts, he keeps calm. But as the tremors stretch on and on, the ground rips apart, the dock disintegrates, and chunks of land fall into the Strait. When the quake finally ends, there's only one thing on his mind: his daughter. Mika's singing songs and laughing with a gaggle of other sixteen-year-olds as they climb into the Pacific Northwest mountains for a scout weekend. One minute, it's sunshine and good vibes, and the next, it's screaming and chaos.

At the end of the world. Nick Peterson never expected to be stuck with a bunch of kids. A 17-year-old boy shouldn’t be responsible for keeping other people alive. But he didn’t have much choice in the matter. That’s what happens when everyone else dies.
