"A blistering, high octane thrill ride to the brink of humanity's extinction. Nicholas Sansbury Smith plunges the reader right into the middle of the action, alongside a cast of unforgettable characters, as they fight tooth and nail to survive one impossible mission after another-to stop an extinction level virus. The Extinction Cycle series is post-apocalyptic, military science fiction at its best. Highly addictive!"―Steven Konkoly, USA Today bestselling author
