When Zoe realizes that everyone she loves is disappearing, she starts running. Scared and alone in a shockingly changed world, she embarks on a remarkable journey of survival and redemption. Along the way, Zoe comes to see that humans are defined not by their genetic code, but rather by their actions and choices.
