As an Army Ranger Jake Blackwell had done four tours of duty only to be taken out by an IED outside Ramadi. The result: traumatic brain injury. His army life was over. Blackouts and memory loss were part of the problem. Jake had no choice but to work for himself as a handyman. His last job seemed normal enough until he stumbled across a package of blueprints. But what kind of blueprints had the word detonator? The plans were for a nuclear device known as the backpack nuke. Someone could take out several city blocks with the thing. Why were those blueprints in that house? Who was the owner, and why did he have them? Jake pursues the answers to these questions, risking not only his own life, but the lives of his family to stop the unthinkable from happening.
