Peter Ash came home from the wars in Iraq and Afghanistan with only one souvenir: what he calls his "white static," the buzzing claustrophobia due to post-traumatic stress that has driven him to spend a year roaming in nature, sleeping under the stars. But when a friend from the Marines commits suicide, Ash returns to civilization to help the man's widow with some home repairs. Under her dilapidated porch, he finds more than he bargained for: the largest, ugliest, meanest dog he's ever encountered ... and a Samsonite suitcase stuffed with cash and explosives. As Ash begins to investigate this unexpected discovery, he finds himself at the center of a plot that is far larger than he could have imagined ... and it may lead straight back to the world he thought he'd left for good.
