Extinction Evolution (The Extinction Cycle Book 4) (The Extinction Cycle, 4)

The fourth book in USA Today bestselling author Nicholas Sansbury Smith's propulsive post-apocalyptic series about one man's mission to save the world.
Central Command is gone, the military is fractured, and the surviving members of Team Ghost, led by Master Sergeant Reed Beckham, have been pushed to the breaking point.

Betrayed by the country they swore to defend and surrounded by enemies on all sides, Team Ghost has one mission left: protect Dr. Kate Lovato and Dr. Pat Ellis while they develop a weapon to defeat the Variants once and for all. But after a grisly discovery in Atlanta, Kate and Ellis realize their weapon might not be able to stop the evolution of the monsters.

Joined by unexpected allies and facing a new threat none of them saw coming, the survivors are running out of time to save the human race from extinction.
There's a storm on the horizon... pick up the series that D. J. Molles said "delivers unrelenting, unmerciful action" before it's too late!
