Search - Water Witch

This book, co-written by Cynthia Felice, was Connie Willis' first published novel. (1982).
Unfortunately, although this book is a perfectly acceptable sci-fantasy adventure, it does not show any of the witty, original aspects that have subsequently catapulted Willis to the forefront of her field.
The cover blurb is by Andre Norton, and it reads very much like it was strongly influenced by Norton.
On a desert planet, controlling the underground water supply is of primary importance. Unfortunately, infighting has decimated the nobility, and the final surviving princess has none of the hereditary water-witch mental powers needed - instead she relies on computers - and seems to be making shady deals with off-worlders for weapons and more.
Her trusting fiance tries to do damage control on the situation - but a flyer accident strands him in the desert - where he meets another victim of recent disaster - Deza, a young woman whose life has been that of a con-artist, pretending to be a water-witch herself, along with her father.
Now, her father has been killed, and her father's spirit seems to be able to telepathically communicate with her through an animal known as a mbuzi - the bones of which have long been associated with both the water-witch powers and other legends - and which now seem like they may become a hot commodity off-world...

The complexity of the situation here deserves more than a 200-odd page book, and although the book is entertaining, it doesn't achieve greatness.
