A foul amber mist descends over every major city in the world, and the populations begin to disappear. By nightfall, every soul in every metropolis is gone. When Sam and his brother return from a mountain camping trip, they find empty streets back home.

And then lizards came. The size of men, they flooded the city and attacked the few remaining humans. When these mutated creatures are confronted by giant spiders, the two species fight each other for the remaining food supply
...with the humans caught in the middle.

A teenage boy with electric powers. A college student who can communicate with animals. A scientist with a secret. And a band of psychopaths with their own agenda.

Defending each other from the evils of men and creatures alike, the last humans race to unravel the mystery of the empty cities, the swarming creatures, and the disappearance of humankind.
