What happens to us when we die? Is there really an afterlife? Do we possess a soul? Does God exist? For Michael Gabriel, the answers to these questions lie in another dimension, a realm of eternity where there is no concept of time, only pure life force, pure existence, and pure evil.

Now, as was foretold five hundred years ago in the Mayan Popol Vuh, Michael's sons are born: white-haired, azure-eyed Jacob, blessed with inhuman physical prowess, intelligence, and insight into the cosmos, and dark-haired Immanuel, who refuses his genetic calling, desiring only a normal life. Only the combined powers of the Gabriel twins can resurrect their savior-father and save the human race from an eternity of repeating its own self-destruction.

But on this fateful day another child is born. Exposed to the uglier side of existence and empowered by her posthuman genetics, the beautiful, schizophrenic Lilith will travel down a darker path that leads to eon-distant Xibalba (the Mayan version of Hell) and an epic battle of good versus evil and the final destiny of the human race.
