Acorna series

A lady unicorn drifting in a spaceship is found to have unusual healing powers. As word spreads, various groups on Earth, from scientists to politicians, try to steal her so as to use her for their own ends. But the miners who found her are protective. Although she has made peace with her Linyaari heritage, Acorna knows that only by returning to the frozen stillness of space will she ever truly feel at home. But the solitude she desires must wait....

With the help of her "uncles" and the thousands of humans who love and admire her, Acorna has found her true people, the peaceful, telepathic Linyaari.

The homeworld Acorna has never known was horribly scarred in the brutal attack by the cold-blooded Khleevi, but the Linyaari -- the unicorn girl's gentle, spiritual race -- live on. Now is the time for healing and rebuilding, for restoring the natural beauty corrupted by the savage insectile oppressors. But Acorna's Linyaari friends and colleagues begin mysteriously disappearing soon after work gets under way, among them her beloved Aari. And her...

Acorna looks forward to rebuilding her home world with her newly returned life-mate Aari, but something seems very wrong with Aari's behavior.
