Hellhole trilogy

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...

A confrontation between General Adolphus and the fleets of Diadem Michella Duchenet is compromised by a shadow-Xayan mental blast, an imminent asteroid collision in the outer Candela system, and a fanatical band of rogue telemancers.
