Archaeologist Julius Gabriel devoted his life to studying the Mayan calendar, a 2500-year-old enigma that predicts the end of humanity. But when Julius dies before solving the prophecy, only one person can save the human race from annihilation: Julius’s son Mick, a patient in a mental hospital.
Meanwhile, on the fall equinox, a serpent's shadow appears on the northern balustrade of the Kukulcan Pyramid, just as it has done for a thousand years. But this time, a rare galactic alignment occurs, and a space transmission reaches Earth.
It is the beginning of the end . . . and of this series of thrillers from bestselling author Steve Alten.
