The Wilding — C.S. Friedman

It is two hundred years since the great Braxana general Zatar the Magnificent, and the psychic Azean general Anzha lyu Mitethe pursued their personal war among the stars, and in doing so altered the very flow of human history. The psychics of the Azean Empire have since scattered in fear, taking shelter in regions of space where the Empire dares not follow. They are legendary creatures now, rumored to be half mad from the mental fallout of their homeworld's destruction. Now, the Azean Empire no longer seeks to breed for psychic potential, believing this trait to cause psychological instability, In the Braxin Holding, the ruling Braxana tribe has attended to the needs of its dying gene pool with typically barbaric élan, resurrecting traditions that more civilized peoples abandoned long ago. In the shadow of their newfound genetic fixation other Braxin tribes stir, wondering if the time for revolution has come at last....

Fleeing Braxana justice, a Kesserit warrior named Tathas finds himself bound on a quest any sane Braxin should fear more than death itself....

Searching for the key to her heritage, an Azean Mediator named Zara discovers there are landscapes within herself more terrible than any alien battlefield....

Seeking her long-lost kin, the renegade psychic Rho will find both Tathas and Zara, and with their aid will set in motion the final phase of an ancient vendetta -- a vendetta dating back centuries to those two great generals who made the Endless War their personal battlefield.
