When a zombie virus tears the world apart, Olivia discovers the last person she ever expected to see alive—her former enemy, Ethan—has become a zombie.
But Ethan is different.
He may have lost his humanity, yet he still remembers Olivia. Even more terrifying, he can think, feel, and repeatedly risk his life to protect her. And somehow, his body is immune to the virus.
Desperate to save Ethan and find a way to end the apocalypse, Olivia takes him on the run. But as deadly survivors, ruthless factions, and hordes of infected close in, Olivia uncovers a shocking secret: Ethan’s unique antibodies could be the key to creating a vaccine—and saving the human race.
To everyone else, Ethan is a monster.
To Olivia, he’s the one person worth saving.
But what happens when the world discovers the cure is trapped inside a zombie?
