Last night I finished reading Rogue Warrior: Vengeance by Richard Marcinko. I really liked this book. Richard Marcinko is a former Navy SEAL and the founder of Seal Team 6 and Red Cell. He currently lives in northern Virginia, where he is CEO of SOS Temps, Inc. - his private security firm, whose clients are governments and corporations; Richard Marcinko, Inc. - a motivational training and team-building company; and Red Cell International, Inc. (a.k.a. Red Cell II) - which conducts vulnerabilty assessments of high-value properties and high-risk targets.
I have read all of Richard Marcinko's Rogue Warrior novels. Richard Marcinko's "Red Cell mentality" has made it possible for him to predict future terrorist events and capabilities in his novels. Richard Marcinko's next novel, Rogue Warrior: Holy War, comes out next year.
