The Long Fall of Night - The Long Fall of Night, #1

In a flash, everything changes. When NYU student Asher Caine's uncle calls to warn him something big is coming, he has no idea it will be so devastating. Not even years of training can prepare him for what he's about to face. The only plan he has is to get his sister and nephew across country to safety, whatever it takes. The darkness is full of potential. For good or evil, only time will tell. Elliot Davenport isn't about to let his Chemistry lab partner leave him behind, though he's never done a spontaneous thing in his life.
Ash is mysterious, aloof, and so damned sexy, Elliot can't get the guy out of his head. But his crush takes a backseat as the gravity of the situation becomes clear: the eastern two-thirds of the United States has gone dark. What happens when all the rules change in a split second?200 million people are without access to sustainable food and water, let alone coffee and the Internet. Facing the worst humanitarian crisis the western world has ever seen, the government calls the military to step in.
The entire military. The soldiers of Team Shockwave are tasked with evacuating civilians to the safety of refugee camps, and then patrolling the new border between the East and West. Shockwave are on the front lines and the fate of an entire nation rests on them. Welcome to the long fall of night.
