Nestled in the Appalachian Mountains and dissected by three rivers, Pittsburgh, Pennsylvania is an idyllic city. It's quiet, the traffic is nonexistent, and floating down the Allegheny River on a boat is peaceful and serene. It's perfect... as long as you can ignore the mindless monstrosities roaming the streets, the bloodthirsty creatures ruling the night, and the insane, power-hungry human survivors. Lance York awakens in a quarantined hospital as a devastating plague spreads worldwide, devolving mankind into unspeakable horrors. With the help of an unlikely ally, the sexy, snarky Cass, Lance must navigate through the collapsing city, striving to escape the madness of the unfolding apocalypse around them.
