In ancient Mexico, the "End-Time Codex"--prophesizing the world's end in 2012--is entombed. A young Aztec-Mayan slave tells us its story. Gifted in math and astronomy, Coyotl rises to king's counselor in Tula, a golden city of milk and honey ruled by the brilliant god-king, Quetzalcoatl, the Feathered Serpent of lore. Gathering artists, scientists and craftsmen, this legendary ruler builds a city that will awe humanity for one thousand years. But he also faces war, catastrophic drought, betrayal and the rise of an evil death-cult religion. Instituting the infamous "Blood Covenant," its priests drag thousands of people a year atop temple-pyramids and rip their hearts beating from their chests. To stop them Quetzalcoatl must defy the flames of bloody civil war. A thousand years later scientists discover the End-Time Codex. While struggling to decipher it, they realize their own age mirrors Tula's. Can they crack the 2012 code and save their world from Tula's deadly fate?
