A deadly contagion has spread across the country, turning the afflicted into violent monsters and the streets into killing grounds. The government has fallen. Once great cities lay in ruins. And those cursed with immunity have braved the chaos to take shelter in military bases unprepared to withstand the continuous attacks of the infected.

But that’s not the worst part.

An ancient evil hell-bent on bringing about the end of the world has awakened. Fortunately, a Hopi elder who’s spent his entire life awaiting the fulfillment of the prophecies foretelling its return has traveled the highways, leaving signs summoning the chosen to the site of humanity’s last stand.

If they can reach it in time.

An FBI agent and a prescient teenage girl need to fight their way down the west coast. An expert on indigenous languages and a woman with precognitive abilities must battle inland from the east. And a pair of scientists have to escape from a doomed research facility so they can share a discovery that the entire world needs to know: The virus runs its course in 72 hours. All the immune have to do is survive that long.

And pray the forces of darkness don’t find them first.
