Doomsday Serenity (The Doomsday Chronicles Book 2)

On the dawn of the holocaust, no one is prepared to face the end of the world. But Asher Cullen isn't like everyone else.

Trapped in a life of monotony with no friends or family, Asher trudges through his seemingly meaningless life each day, sitting behind his office desk and wondering what the point of it all is. He wants a purpose, a real reason to get up in the morning. What he gets is global annihilation. But contrary to the rest of America, its citizens, government, and doomsday preppers, Asher doesn't react with panic or horror. This is his opportunity to finally grab life by the horns.

After teaming up with Olivia, an escapee from the local loony bin, Asher survives in style, reconnecting with his childhood street gang and fighting through a desolate Knoxville, facing crazed veterans, cannibals, and more, all the while still searching for his life's purpose and finding it in the most bizarre of places. Using the gun he once kept for his eventual suicide, he learns to use it as a tool for preserving life instead--but his empire stands tall, and its fall would be devastating. If he's not careful, his world might end all over again.
