The Unbound Empire - Melissa Caruso (Book 3 in the Swords and Fire series)

While winter snows keep the invading armies of the Witch Lord Ruven at bay, Lady Amalia Cornaro and the fire warlock Zaira attempt to change the fate of mages in the Serene Empire forever. But on the night of Raverra's great masquerade, Ruven executes a devastating surprise strike at the heart of the Empire - threatening everything Amalia holds most dear. To stand a chance of defeating Ruven, Amalia and Zaira must face their worst nightmares, expose their deepest secrets and unleash Zaira's ravaging fire.

THE UNBOUND EMPIRE is the epic finale to the spellbinding tale of courtly intrigue and dangerous magic that began with THE TETHERED MAGE and THE DEFIANT HEIR.
