"Now, as was foretold 500 years ago in the Mayan Popol Vuh, Michael's song are born: white-haired, azure-eyed Jacob, blessed with inhuman physical prowers, 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." --- Book Jacket.
