THIS IS THE WAY THE WORLD ENDS

On a warm summer night in New York City, the apocalypse begins.

Within days, the deadly Medusa virus is sweeping the globe like a wildfire, pushing humanity to the brink of extinction.

As civilization crumbles around him, survivor Adam Fisher will discover a flicker of hope that will send him on a quest through a ruined American landscape.

He joins forces with Sarah Wells, a soldier harboring a tragic secret, and Freddie Briggs, an aging football star grieving the loss of his family.

In a post-plague world, the group will endure challenges unlike any they have ever known, including the rise of a dangerous new enemy that will threaten the survivors' fragile existence.
