For the last five years, Colin Pearce has been hiding from the CIA and hiding from himself. He's been living under an assumed name in an isolated place, flying tourists in the OV-10 aircraft, drinking single-malt whiskey, and avoiding companionship.

But all of that changes when a former CIA comrade shows up planeside at Pearce's workplace - a woman he left for dead during his time with the Agency. On a flight over the scenic landscape of Sedona, Arizona she tells him she's not there to recruit him, she's there to warn him. It seems the Pearces's boss, Ian Brooks, used to work for the CIA as well. Brooks was at the center of a project that was ultra-classified and involved technology that was deadly beyond imagination. And now, he may have gone rogue.

After swearing that he would never get involved in another CIA operation, Pearce is drawn into a complex plot that has him working with new and familiar allies. He'll risk his life against unexpected and ruthless enemies he thought were long vanquished and battle them at the controls of the mighty A-10 Warthog. And along the way, he'll be forced to conquer the violent darkness inside himself or die in the attempt.
