A little more than thirty years ago Tom Clancy was a Maryland insurance broker with a passion for naval history. Years before, he had been an English major at Baltimore´s Loyola College and had always dreamed of writing a novel. His first effort, The Hunt for Red October-the first of the phenomenally successful Jack Ryan novels-sold briskly as a result of rave reviews, then catapulted onto the New York Times bestseller list after President Reagan pronounced it "the perfect yarn." From that day forward, Clancy established himself as an undisputed master at blending exceptional realism and authenticity, intricate plotting, and razor-sharp suspense. He passed away in October 2013

Mark Greaney has a degree in international relations and political science. In his research for the Gray Man novels, including Mission Critical, Agent in Place, Gunmetal Gray, Back Blast, Dead Eye, Ballistic, On Target, and The Gray Man, he traveled to more than fifteen countries and trained alongside military and law enforcement in the use of firearms, battlefield medicine, and close-range combative tactics. He is also the author of the New York Times bestsellers Tom Clancy Support and Defend, Tom Clancy Full Force and Effect, Tom Clancy Commander in Chief, and Tom Clancy True Faith and Allegiance.
