Daindreth's Empress. Daindreth's Assassin, #5

An empire can have only one ruler.  Amira Brindonu Fanduillion has been crowned alongside her husband, the rightful heir to the Erymayan Empire. They have survived assassination attempts and schemes within the palace to retake the throne and begin their reign. It appears to be their moment of victory, until reports of a rampaging demon horde reach them from the countryside.  Vesha, Daindreth's mother and the former empress, has made a deal with a fallen goddess for the empire's protection.
But no one wins a deal with demons and as the cythraul spiral out of Vesha's control, she grows more desperate by the day. She hopes that by freeing the fallen goddess, order will be restored-but at what cost? Alongside, Thadred and their Istovari allies, Amira and Daindreth set out to stop Vesha and her demon horde, hoping they will be able to reach her in time. The stakes have never been higher and more than just the throne could be lost. As the very gods vie for control of the continent, Amira and Daindreth's work to bring peace might be over before it has begun. Daindreth's Empress is the thrilling conclusion to the Fantasy Romance Daindreth's Assassin series.
