United States of Z - Book 5: A Post-Apocalyptic Thriller
They finally found hope. Now they must outrun the man ready to burn it down.
After a desperate search across a dying nation, Dr. Halbrook has been found—alive, and holding the key to finishing what Dr. Carter began. Now Mark Moon leads a small, battle-worn team on a mission that can’t deliver Halbrook the vaccine sample… and Moon’s own lifesaving blood.
But while hope rises, a new threat emerges from the ashes.
Vargo—once a monster in the shadows—has resurfaced with a brutal militia at his back. His newest a Minuteman III ICBM missile silo, fully operational and under his control. If he launches, the world won’t just fall… it will burn.
As Moon races to save humanity’s future, Vargo prepares to destroy it.
The cure may save the world—if they can stop the man determined to end it.

An Exciting Read
This series is so good! Book 5 was hard to put down. All who's left of Protocol 9 are busy and tired but they're not done yet. As soon as one mission is over, something else happens. I knew we'd see Vargo again though. I found the story entertaining and educational. I was googling ospreys and silos to get a picture of what they actually looked like. But its still not over. Will we ever get a cure? Will they find the Dr.? Is he even still alive? What about Allman's boys? There's still more we need to know. I'm excited for Book 6.
