Mankind's dominance has come to an end ...

When a terrorist group detonates a small nuclear device at a level four biohazard facility, it releases the infection vectors stored within and creates a contagion that devastates the planet.

Entire species are wiped out, while those that survive are genetically transformed into prehistoric mutations of their former self.

Secret Service agent Alex Durham is assigned to protect the president. As the dangers of the expanding nuclear fallout become apparent, he accompanies the country's leadership as they seek shelter from the impending contagion.

When they emerge weeks later, the global aftermath of the terrorist attack leaves the survivors struggling to find safety in a world that has regressed millions of years. Creatures from the past and those newly created rise to challenge mankind's dominance.

All that matters now is survival ...

Walt Browning, the bestselling author of Extinction Survival, returns with this harrowing post-apocalyptic survival series. Don't miss this tale about people trying to survive the consequences of man's arrogance, all while somehow maintaining their humanity.
