I took out a book from the bookmobile in (1989?), and have never been able to track it down again. Memorable because it was one of the first adult sci-fi books I read, and I've been trying to track it down off and on for 15 years.
Plot details
It was a sci-fi novel where people had three forms: human, animal, and wind. They could stay in the wind form forever, but had a limited amount of time in the others.
There was an advanced spaceship that looks like a manta-ray or a sting ray. I think that the ship could cloak?
It was an adult book, with enough sex scenes that they probably shouldn't have let me take it out of the library.
Book Appearance Details
I remember it having a photo of the ship on the cover, and being around 300pages in length.
That's all that I can remember, any help would be appreciated.
