Cyteen
From back cover Warner paperback February 1989:

ARIANE EMORY IS DEAD.
BUT NOT FOR LONG.
WHERE IS ARIANE?

For fifty years, Dr. Ariane Emory has dominated politics on Cyteen Station.  Because Dr. Emory controls Reseune, a city-sized factory that creates the one item essential to the planet's wealth.  *Reseune produces people* -- computer-trained azi servants and soldiers.

Then Araine Emory is assassinated.  Yet her rivals and victims, people like Dr. Jordan Warrick, his cloned son Justin, and Justin's azi brother Grant, are not freed by her death.  For Emory's murder has turned Reseune into a vast, tyrannical experiment: an attempt to merge nature -- and nurture... biotech -- and cybernetics... genetics -- and psychology... heredity -- and environment.  Cyteen's labs can grow clones, but Ariane Emory's followers want more.  Much more.  The want to re-create Ariane.
