Shadow on the Stones — Moyra Caldecott

THE PRIESTS OF THE SUN FACED THE GOD OF DARKNESS

From the west they came like an all-devouring locust swarm--the armed horde of invaders who followed their savage king and sullen queen and terrifying dark god Groth.

At first the news of rapine and pillage came only as troubling rumors to the sacred priesthood of the Temple of the Sun. But all too soon the danger was close and salvation frighteningly far away--as the most ancient magic trembled before the most perverse and potent threat that the forces of light had ever known and that only the ultimate act of daring could defeat...


This novel concludes the story of Kyra, priestess of the Temple of the Sun, who with her husband, the Lord Khuren, has guided their civilization to a time of spiritual strength, psychic energy, and communal peace.
