Now four years later, as she steps out from the fallout shelter and into a zombie-infested world, he’s the only thing on her mind. Thanks to her father Peyton is now built to survive: with razor tipped nails, ocular implants and cybernetics that make her stronger, faster, and able to protect herself in a world filled with monsters. Yet all the weapons in the world can’t protect her heart when she runs into Chris again. The once sweet boy of her childhood has now grown into a tortured man--still furious at her for breaking his heart and never telling him why. Now the two of them find themselves on the run, forced to fight their way down the monster strewn east coast to reach the last human outpost on Earth: Walt Disney World. Can they find a way to let go of old hurts and regain the love they lost--all while attempting to save what’s left of the human race?
