Safe for the moment from the zombie hordes spreading across the globe, Mags Vissers and Ash should finally be able to breathe easy. But separated by thousands of miles, with the zombie virus still rampant and its creator, Dr. David Warren, on the loose and searching for Mags and Ash, the women know that time is running out for everyone. So when a chance to stop the spread of the walking dead presents itself, Mags finds herself forced to help. And why not? After all, at least Ash is safe, right? And surely the world will welcome the immunity that a new vaccine promises. Little does Mags know that they'll meet more resistance to the cure than they bargained for, and that Warren is closing in on Ash, preparing to spring a trap that will ensnare both Mags and Ash, ensure his own victory, and maybe-just maybe-turn the undead throngs into his own personal army. Humanity's last hope for survival lies in the hands of a cancer survivor and a kid in a wheelchair. And one final time, Mags must do what she does best-run, fight, and stay alive-in a battle that has become more than personal, because it's a fight to save not just herself but her new family as well.
