Once Upon a Time . . . Traveler

The travelers are back, with supercharged push-button technology to control time and space. A martial-arts prodigy and a counterterrorism agent are swept into the pre-Flood world where hideous giants are at war with mankind, aided by spirits with frightening powers. While history accommodates them, it also constrains them, requiring cunning and creativity to affect justice and to rescue the doomed as their skills are stretched to the limit.
Light deals with the genetic corruption preceding the Flood and how modern genetic enhancement plays into this model in the Last Days. He integrates potential pre-Flood physics and cosmology with the possible technologies available to the first generations of humanity.
The biblical dawn of man included gargantuan animals, strange landscapes, and spirit-born technologies, an early light of brilliance snuffed out by sin and violence. Dawn's early light will shine again upon the Redeemer's return.
