Unleashed: V Plague Book 1 (Volume 1)

John Chase has just arrived in Atlanta on a routine business trip when America experiences the worst attacks in history. Nuclear bombs destroy cities and the widespread release of virus-laced nerve gas sends the majority of the surviving population into a murderous rage. Rescuing Rachel, he must lead her to safety as Atlanta burns, raging infected roam unchecked and society disintegrates into savagery.
