Fate of the Free Lands by Jack Campbell
The end of the Jules trilogy. Spoilers ahead for the earlier volumes
Jules has escaped and is trying to reunite with her crew, and protect the free lands. The Mechanics still think they control her, which wins her some advantages. The Mages are searching for her and manifesting strange birds. Meanwhile, Jules is worried about having her child, between the father and the question of safety.
Much happens, including the Empire deciding to do something, and the free lands acting.
