The body of a young woman found in an Arizona border town walks out of the morgue. To the CDC investigator called in to consult the local police, it's a bizarre medical mystery. More bodies, dead of a mysterious disease that solidifies their blood, begin disappearing from morgues nearby. In a futile game of catch-up, the CDC, the FBI and the US government realise that it's already too late to stop it: the vampire epidemic will sweep first the United States, and then the world. Impossibly strong, smart, beautiful, and commanding, these creatures refuse to be called 'vampires', they prefer 'gloamings'. They quickly rise to prominence in all aspects of modern society: physically graceful at sports, endlessly enthralling on TV and incredibly intelligent at business - soon people are begging to be 're-created', willing to risk death if their bodies can't handle the transformation. But just as the world begins to adjust, the stakes change yet again when a charismatic and wealthy businessman, recently turned, decides to do what none of his kind has done before: run for political office.
