Best one in the series.

A tangled mess with a private security firm, US mercs working for a foreign security agency, Iranian nut jobs working for the same agency and a Russian hit squad helped by a high-level CIA staffer combine to create a number of convoluted storylines. Add in a health-compromised Grey Man who miraculously functions at full health as the book nears its conclusion. And, who takes an elevator to exit a hotel when a fire alarm goes off?

Amazing as always. Love the parallel story lines. The vulnerabilities built in to the Grey man so he isn’t Superman.

Besides the flying Russian

Suspenseful and full of action!

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.

Fast read

This Dude is RELENTLESS! Best book so far! Lets go!

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!

I enjoyed this story. There were a number of plot twists and story lines that kept the book fast paced and exciting.
