In Bright of the Sky, Kay Kenyon introduced a milieu unique in science fiction and fantasy: The Entire, a five-armed radial universe that exists in a dimension without stars and planets and is parallel to our own universe. Stretched over The Entire is a lid of plasma, called the bright, which ebbs and flows, bringing day and twilight. Under the vast canopy of the bright live many galactic species, copied from our own universe.

Former star pilot Titus Quinn loves The Entire, but now he must risk annihilating it by destroying the fortress of Ahnenhoon. To sustain a faltering Entire, Ahnenhoon's great engine will soon reach through the brane separating the universes and consume our own universe in a concentrated ball of fire.

Quinn sets off on a journey across The Entire armed with the nan, a small ankle bracelet containing nanoscale military technology that can reduce Ahnenhoon and its deadly engine to chaos. He must pursue his mission even though his wife is held prisoner in Ahnenhoon and his own daughter has sent the assassin MoTi to hunt him down.

As he traverses the galactic distances of The Entire, he learns more of the secrets of its geography, its fragile storm walls, its eons-long history, and the factions that contend for dominance. One of these factions is led by his daughter, who though young and a slave, has at her command a transforming and revolutionary power.

As Quinn wrestles with looming disaster and approaches the fabled concentric rings of Ahnenhoon's defenses, he learns that in the Entire, nothing is what it appears. Its denizens are all harboring secrets, and the greatest of these is the nature of the Entire itself....

Kay Kenyon, noted for her science fiction world-building, has in this new series created her most vivid and compelling society, the Universe Entire. In a land-locked galaxy that tunnels through our own, the Entire is a bizarre and seductive mix of long-lived quasi-human and alien beings gathered under a sky of fire, called the bright. A land of wonders, the Entire is sustained by monumental storm walls and an exotic, never-ending river. Over all, the elegant and cruel Tarig rule supreme.

Into this rich milieu is thrust Titus Quinn, former star pilot, bereft of his beloved wife and daughter who are assumed dead by everyone on earth except Quinn. Believing them trapped in a parallel universe--one where he himself may have been imprisoned--he returns to the Entire without resources, language, or his memories of that former life. He is assisted by Anzi, a woman of the Chalin people, a Chinese culture copied from our own universe and transformed by the kingdom of the bright. Learning of his daughter's dreadful slavery, Quinn swears to free her. To do so, he must cross the unimaginable distances of the Entire in disguise, for the Tarig are lying in wait for him. As Quinn's memories return, he discovers why. Quinn's goal is to penetrate the exotic culture of the Entire--to the heart of Tarig power, the fabulous city of the Ascendancy, to steal the key to his family's redemption.

But will his daughter and wife welcome rescue? Ten years of brutality have forced compromises on everyone. What Quinn will learn to his dismay is what his own choices were, long ago, in the Universe Entire. He will also discover why a fearful multiverse destiny is converging on him and what he must sacrifice to oppose the coming storm.

This is high-concept SF written on the scale of Philip Jose Farmer's Riverworld, Roger Zelazny's Amber Chronicles, and Dan Dimmons's Hyperion....
