One hundred and fifty years have passed since the tenure of the Archangel Gabriel and his angelica Rachel, a time of peace and stability. But now, great storms are sweeping the lands, the deserts flood, and the skies rain down death and destruction.

Then the proud and beautiful Archangel Delilah falls victim to the rage of wind, as she is torn from the sky, her wing broken. She can no longer soar in the heavens, guiding and guarding those below. She can no longer be first among the angels.

Never before have the oracles had to choose a new Archangel while one still lived. And though Jovah's anger blows all about them, still they must consult him. His choice - the angel Alleluia, a solitary scholar of undistinguished lineage. Now the fate of the planet rests with the reluctant Archangel Alleluia, who believes in her duty and her god. And her fate in turn, may well depend on the mortal Caleb, a man who believes only in science - and himself.
