As a Miami narcotics detective, Leah Daniels never knows how her day will turn out. But she certainly doesn't expect to be strapped to a stone altar as the human sacrifice in an ancient Mayan ritual meant to coax a demon from the underworld - or to be saved by a handsome warrior-priest king, who claims to recognize her from his visions. Striking Jaguar thinks he is the last of the Nightkeeper warrior-priests, but as the end-time approaches, his mentor reveals there are twelve others. In reuniting them, Strike - king by birthright - gains the power to summon a Mayan god to combat the demons. But the woman of his visions is the gods' chosen sacrifice. Now he must decide between love and duty...or find another way to invoke otherworldly magic in a death-defying race against the end of time.
