The Zombie Swarm... The undead have been defeated in Redwood Grove, but reports of similar outbreaks are coming in. What seemed to be an isolated event is turning into a pandemic. The last thing Ashley Parker wanted when she went to college was to become a zombie hunter. But she is one of a select few who are immune to the virus. Gifted with enhanced speed, strength, and senses, she's recruited by a shadowy organization that's existed for centuries, its sole purpose to combat the zombie threat. Dark secrets begin to emerge, and when an unknown enemy strikes, Ashley and the other wild cards embark on a desperate mission to reach San Francisco. If they fail, the plague will sweep the nation unchecked. And the person she cares for most may die. Or worse.
