United States of Z - Book 6: A Post-Apocalyptic Thriller

The fight is over. Hope is dead.

United States of Book Six
The final chapter.

Vargo is gone. The missiles are silent. And the cure is farther away than ever.

Dr. Halbrook has vanished without a trace—taking humanity’s last chance with him. No body. No answers. Only the certainty that without the cure, the world will rot until nothing is left.

Mark Moon has one final option.

With fractured intelligence and nothing left to lose, Moon heads east into the frozen ruins of Russia, hunting the only remaining antidote known to exist. No backup. No extraction. No promise of survival.

The dead no longer matter.
Time does.

One man. One mission. If he fails, the United States dies with him.

Rating is for the series

"Fast and furious", is the wording by this author and is correct. Never a dull moment. I would, however, like to have known what happened to all the Carriers. There was no ending for them.....how do you come back?😁

Boom.

Bang up finish to the series, lots of action and drama and ended on a high note. Wonder if we'll get to see what happens in Russia.

Entire Series is AWESOME

I can’t more highly recommend this series! Awesome from page 1 of book 1 to the very end of book 6. Characters are well developed, and Mark Moon is THE best of all.

Worthy Series

This is the first series that I have read by this author, but it most certainly will not be the last!! I absolutely LOVED the fast-paced writing, without all the unnecessary and unrealistic hoopla, writers tend to include. I enjoyed the camadarie and brotherhood. I loved that you could, honestly, respect and root for the heroes of the series. As, well, as have contempt and pity for the villains and victims.

If you love zombies, soliders, and more twists and turns than you can probably count this is the series for you..... Be prepared!! There is a lot of LOSS in these pages, you will smile, but you could just as easily cry.
Remember, this is a zombie series with the blood and death to prove it.

What a huge let down. Any semblance of humanity or character built over the last 5 books down the drain. I cant get over the idiocy of bringing contaminated blood in glass vials in a makeup bag and actually killing other service members. Or unleashing the virus on a populace who was innocent. It would eventually spread across the whole landmass and cause BILLIONS of deaths! Is this actually the real book? not trolling? two psychopaths kill billions of people?

Great books to read, characters were quickly formed to identify to. Loved every one of the six books, could not put them down.
