"There was video of the second shooter. There was video."In the first reports of every mass shooting, there's always mention of a second shooter-two sets of gunshots, a figure seen fleeing the scene-and they always seem to evaporate as events are pieced together.Commissioned by a fringe publisher to investigate the phenomenon, journalist Mike Karras finds himself tailed by drones, attacked by a talk radio host, badgered by his all-knowing (and maybe all-powerful) editor, and teaming up with an immigrant family of conspiracy buffs.Together, they uncover something larger and stranger than anyone could imagine-a technomystical plot to 'murder America.'Time for Karras to meet his deadline.
