Rate this book
One nation. Millions of dead.


When a viral outbreak turns most of the population into violent, animalistic predators, the agents are activated. Their to navigate the chaos, stop the enemy behind the virus, and save humanity before there’s no one left to save.

One month after the outbreak, Protocol Agent Mark Moon wakes to a nightmare—his men lost and left behind in a city overrun by the infected. Driven by loyalty and haunted by guilt, Moon must return to the very place where the Ares plague first consumed the nation.

Every step brings him closer to the truth—and closer to death. Can he find his men before the virus claims him, too?

Meanwhile, virologist Dr. Ava Carter races against time as the Ares plague spreads like wildfire. The fate of humanity hangs in the balance of a cure that may never come.

Protocol 9: Where loyalty is tested, and survival comes at the highest price.

Well, thanks to Mr. Lester I was a bawling, blubbering mess last night reading this book. But, oh my goodness, it is so good. I was up way too late reading while sick ( no regrets ) as I kept saying just one more page. I one more paged till 2 am. This is the second book and it is just as good as first one. If not a bit more in depth with the characters. Moon is my favorite character. I’d want him to lead any military, period!! I truly can’t recommend this book enough. Beautifully written, beautifully edited. I didn’t have to read and read the same paragraph over and over to understand it. If you don’t grab any books, grab this and first one and begin. You won’t be sorry.

Not a good stand-alone novel, character development and world building suffer. DNF 35%.
