Bullets, Bombs, and Mayhem! Think 'American Sniper' meets 'The Godfather' in this action-adventure thriller. 4.4 Stars on 573 Reader Ratings.

As Bob Burke's 737 lands at Chicago's O'Hare Airport, he sees a man strangling a woman on a rooftop below. No one believes him, of course, but he knows what he saw, and Bob Burke isn't the kind of guy to let a thing like that rest.

Slight of build and now a telecommunications company executive, this "telephone guy' is a former Army Ranger and Delta Force commander. He spent four tours in Iraq and the rugged mountains of Afghanistan running 'special operations' missions, and is one of the most lethal killers the US government ever produced. Over the next three days, he finds himself butting heads with the Chicago mob, crooked suburban cops, a zealous US Attorney, a psychopathic doctor, and his own vindictive soon-to-be-ex-wife, who is trying to take his company away from him. As his big, muscular, Delta sergeants will readily admit, he's the one you don't want to meet in a dark alley.

Whether he's carrying a Barrett .50-caliber sniper rifle, a knife, or only his bare hands, he is equally lethal. So, when the bodies start falling and a young woman needs help, he doesn't hesitate. His new combat zones might be in a glittering high-rise office building, a tract house in a suburban subdivision, or a wooded Chicago Forest Preserve District, but they started it and Bob Burke intends to finish it. And when he needs some backup, he knows just the guys to call.
