Cadmian's Choice — L.E. Modesitt Jr.

Corus has been redesigned to become the new home of a superior race from a distant world whose very life depends on drawing sustenance from the biological life force of a planet. Their plans are supervised by a staff of Alectors, who rule the world. The Alectors alone have access to the huge flying Pteridons they have bred and the superior weapons that underpin .their psychic talents.

The time is now fast approaching for the transfer of the whole population from the old world nearly bled dry of life force to Corus. Neither the Alectors (who will be reduced in status when the real powers arrive) nor the local humans (who seem destined to become no more than cattle, though they know nothing of this) are ready. The situation builds toward an explosive climax.
