This first book in the After Eden series chronicles the rise of nations from the descendants of Cain and the descendants of Seth. When a branch of Cain's line gives rise to the abominable race of Giants, Seth and his followers lay the foundations of the great city of Lhiosquor.

With divine help, the people of Lhiosquor manage to prevent the first generation of Giants from subjugating the human race. However, it is not long before decisions made by some of Seth's descendants set in motion a prophesied sequence of catastrophic events. A new generation of Giants arises, threatening to destroy the City of Light from without as the ambition and machinations of the powerful threaten it from within.

At this time, God raises up the prophet Enoch. Descended from both the line of Seth and the line of Cain, Enoch presents a choice to the people of Lhiosquor and all other free peoples of the world: acknowledge God and receive His favour, or fall to the cruel dominion of the Giants.
