Enemy from the North — Larry Brown

A synopsis of the novel is that three unlikely Special Ops Officers are faced with preventing a cerebral terrorist from implementing a sinister, but brilliant attack to bring America and other Western nations to its knees. If the attack is successful, the carnage will put America in the cross fire and give the terrorists the impetus to topple her as a nation. To counter the attack, the three officers become as ruthless, unforgiving, and singular in focus as the terrorist. As time is running out, they quickly run their own Special Black Ops in their attempt to foil a seemingly never-ending plot that has been meticulously and cunningly planned. Only their Commander-In-Chief is in the loop as the NSA, CIA, and the FBI is unaware of their heroic efforts to thwart the terrorists' evil plot.
