Ex-military contractor Harper Knox has taken over his family’s farm in eastern Washington, ripped up the cherry trees and planted grape vines, hoping that the wine life will ease his PTSD-riddled soul. But he still has nightmares, and he’s still diving into the dirt every time a kid sets off a firework.

Desperate to taste battle again, he accepts a bodyguard gig in Seattle protecting a doctor involved with controversial AI research. Sometimes the only way to deal with the fire is by jumping back into the flame.

Things go bad quickly, and Harper and Italian mercenary Francesca Daly join forces to make things right. Technology and religion collide as the two vigilantes race through Seattle on a hunt for a madman.
