When the dead rise they stop being nice. They're not your friend. They're not your relative, acquaintance, lover, neighbor, or that person who says hi to you at work. The dead have one desire; the blood of the living. They come in the night, and they don't stop. Only the sun holds them back if you can make it to dawn.
A chemical engineer, Hayden Cornell was contracted to study two incapacitated vampires. But a global outbreak forces Hayden on the run, where he joins up with Evelyn Gwinnett and several other survivors. Still set on solving the epidemic and why it didn't spread before, Hayden is further spurred on by a mysterious caller representing those who hired him. Tensions rise, as the secrets of survivors come out and pit them against each other. They also discover some would rather die to vampires than live on in a post-apocalyptic world.
