Extinction Edge (The Extinction Cycle Book 2)

A new threat that will bring humanity to the edge of extinction...
The dust from Dr. Kate Lovato's bioweapon has settled. Projections put death counts in the billions. Her weapon was supposed to be the endgame, but it turned a small percentage of those infected with the Hemorrhage Virus into something even worse.
Survivors call them Variants. Irreversible epigenetic changes have transformed them into predators unlike any the human race has ever seen. And they are evolving.
The fractured military plans Operation Liberty--a desperate mission designed to take back the cities and destroy the Variant threat. Master Sergeant Reed Beckham agrees to lead a strike team into New York City, but first he must return to Fort Bragg to search for the only family he has left.
As Operation Liberty draws closer, Kate warns Beckham that Team Ghost won't just face their deadliest adversary yet, they may be heading into a trap...
The second book in self-publishing sensation and USA Today bestselling author Nicholas Sansbury Smith's propulsive post-apocalyptic series about a soldier's mission to save the world.
