The world, as she knew it, was over for Amy Gouyen even before the mystifying Puissance Virus emerged, turning all those it infected into virtually invincible, super cannibals. While society deteriorated around her, Amy's survival instinct and the fire in her Apache blood served her well and kept her going. But in the Apocalypse, it's only a matter of time before you find yourself in a jam, seemingly impossible to get out of. Just as the jaws of death close in on Amy, Fate plays a wildcard. Elias Kincade enters her life in a storm of bullets and blades, rescuing her from certain demise. Her savior appears to be a charismatic cowboy but it isn't long before Amy discovers, the hard way, that there is more to him than meets the eye. Elias is a vampire, one who is duty bound to not let her go after she's discovered what he is, and he doesn't want to kill her unless she forces him to. An uneasy truce between the two quickly evolve into a partnership as Amy moves deeper into the tumultuous world the vampires face in the Apocalypse. Susceptible to the Puissance Virus--in their own way--the vampires have to diligently protect themselves while a rebellion within their ranks and a play for ultimate power threatens the future of vampire society, as well as the destiny of every uninfected human left on the planet. Secrets about the vampires, humans, chompers, and the Puissance Virus itself are revealed as Amy and Elias find their places in what's left of the world and risk everything to secure a brighter future.
