The Coelura(1983)

Anne McCaffrey

The Lady Caissa, heir to the Ambassador of the Federated Sentient Planets to the world Demeathorn, had grown up knowing that she owed her sire obedience and unconditional loyalty. She was expected to do her duty, even to the extent of entering into a marriage alliance she did not understand with a man she despised. Lady Caissa, beautiful, rich, and well-educated, had never learned the great secret of Demeathorn, although she was about to be caught in its spell.

In the aftermath of disastrous diplomatic negotiations, she fled north toward interdicted territory. A distress signal from deep within the forbidden zone drew her to a rocky island where she would encounter a man alone: intense, handsome, and severely injured in the crash of his antique flyer. Lady Caissa did not know it, but she had just set in motion events which would determine the fate of her family, her planet...and her happiness.
