It has been six years since the demons behond the rebellion in Adara were defeated, and Kallista Varyl was chosen as the new Reinine. But one demon–with abducted members of Kallista’s family in its possession–escaped. Now, finally, word has come that the missing might be found in Daryath, the home her mate Obed abandoned. The Reinine, her now-royal family and all their children make a state visit, and disaster strikes: One of the godmarked is murdered leaving Kallista devastated and her powers weakened. There are children to rescue, slaves to free, the wicked workings of demons to set aright, and a ninth godmarked must be found to make the magic whole. Kallista, though, needs more than magic to heal her this time.
