Hellhole

"After the events of Hellhole Awakening, the people of Hellhole and the shadow-Xayans scramble to rally against the threat from the still-living rogue Xayans. Back on Sonjeera, the Monarchy is in an uproar after their surprising defeat and the breakaway of the Deep Zone planets. The dowager Queen decides to go to Hellhole on a diplomatic mission, hoping to keep her power. But after touring Hellhole, Queen Michella is shaken, and begins to realize that she can never have the old Monarchy back. Before the Queen can return to Sonjeera, she's captured by the rogue Xayans and learns the reason for their attack: the orthodox Xayans had developed their minds to the point where they could evolve and, in so doing, trigger another Big Bang, wiping out everything. The rogue Xayans thought they succeeded in stopping the ascension, but the orthodox Xayans on Hellhole are nearly ready. Now, twenty-two huge asteroids from the outer reaches of the solar system are bearing towards Hellhole, summoned by the rogue sect as a last resort. Can all these lives and the planet itself be saved? Hellhole Inferno is the thrilling conclusion to Brian Herbert and Kevin J. Anderson's Hellhole trilogy"--
