December 21, 2012:nbsp; The fabled Feathered Serpent begins his relentless ascent out of the bowels of the earth, escaping thousands of years of torturous confinement. Controversial astrobiologist and archaeologist Caden Montez-who believes Teotihuacan is the best site on earth to find alien life forms, such as the Serpent-is on his trail.nbsp; While exploring this so-called "City of the Gods"-a place so eerie it terrified even the most ferocious Aztecs-she discovers thatnbsp; the Serpent has broken free.Ancient Mayan priests prophesied that when the God-King returned, he would open the gates to the End Time. Together with an ancient 1000-year-old Mayan warrior-who has crossed the Gulf of Time to save humanity from extinction-the outrageous and beautiful Caden must stop him.nbsp; Scientists, political leaders, and journalists who have long ridiculed Caden's theories have no one else to turn to.nbsp; The Mayans' Fourth Horseman of the Apocalypse is on the move, and humanity's survival hangs in the balance.
