Outside the Gates of Eden

Andreas Prescod is a disgraced archeologist when he discovers a hidden civilization in Antarctica. It turns out this discovery was predicted by prophecy, but it also initiates conflict between the world above and that in Antarctica.
Realities collide as the prophecy, directed by three superior beings worshipped as gods, starts to be fulfilled. That development places Andreas and his wife Eurydice at the center of the impending conflict as a three-way battle begins between gods and two worlds.
Third in the First People Saga, Outside the Gates of Eden continues the story of Andreas and Eurydice's struggle to save a world threatened by war and very powerful gods.
