The Eternal Rose (One Rose Trilogy #3)

Kallista, now Reinine of all Adara, still has demons to seek out. She and her family journey south to her mate Obed's homeland in pursuit of the demon who absconded six years previously with Kallista's temple-bound ilian, Merinda, and her child. But when one of the godmarked dies, Kallista is devastated and her mates must cope without her. A trial by combat is needed to regain custody of a child and a new ninth godmarked must be located in order to make the magic whole again and powerful enough to defeat a truly formidable demon. But Kallista needs more than magic to heal her.
