Rise of the Zombies (Book 3 of The Infected Series)

A failed biological attack by Middle Eastern terrorist ravaged the population of the world. Millions dead, millions more turned into feral creatures that spent their time hunting down a handful of survivors that were desperately trying to rebuild and make a life for themselves.
Several years have passed since the majority of the infected population suddenly dropped out of sight. With the threat seemingly abated, Hunter Ashcroft and other survivors now begin to branch out in an effort to find other pockets of civilization. During an expedition to explore the remnants of Nashville, Tennessee, they are surprised to find a thriving community making their home inside the buildings of a large shopping mall.
College student turned scientist, Rachel Benchley, is among the survivors living inside the mall. Her experiments on the infected revealed a possible explanation for their sudden mass disappearance years earlier. Instead of dying off as a result of the virus that turned them into the creatures they had become, they were evolving and changing once more into something much deadlier and horrific. While popular fiction has many theories how a zombie plague could descend upon the earth, those theories were easily discounted as just stories. Now, the survivors must prepare themselves as those stories become reality and the dead that had once been infected return to life and stalk humans for a nourishing enzyme that will keep them alive.
It doesn€t take Hunter and his people long to learn while it appears on the surface that this sheltered colony living inside the mall has done remarkably well for themselves in this post-apocalyptic world, something sinister has been brewing within their ranks that even their own people were not aware of. As if the threat of a brewing zombie outbreak were not enough, they learn that their own kind are willing to sell their souls to the devil if that€s what it takes to ensure their own survival.
