Greary and Gray man are a magnificent as always. Scarily the plots are becoming of possibilities all too real in today’s world. The evilness of men…and women, are far too relatable in this battle of good vs evil.
Action packed

So many twists and turns with Six and Z! Love the characters and the story they make! Love the accuracy and knowledge of geography, geopolitics, weapons, and technology by this amazing author! None better since Vince Flynn! Thank you for another awesome book….now to start on Sierra Six!
Great read
