Sabrina Devon and her husband Ford are on their way home after five years spent as the first Praxatillian ambassadors to Homeworld, anticipating the birth of their first child, when they barely survive a Kyan attack, one of many by the Kyan and their Reissian allies on Realm worlds. Once home, Sabrina helps defend Praxatillus from one such attack and discovers that the Great Crystal and her baby may be at odds. Then the Kyan launch a surprise invasion, landing Reissian troops to occupy Praxatillus' cities and military installations in a search for the Inheritor of the Great Crystal of Miah. As Sabrina, Baldaran, and other leaders raise the citizens of Praxatillus into a resistance force, the Kyan appear to withdraw from the planet. It looks as though the battle is won when the allied fleet arrives-until the Kyan spring their trap: a massive Way that sucks much of the fleet into it and threatens to engulf Praxatillus as well. A Way from which there is almost certainly no return....
