The Unbound Empire (Swords and Fire Book 3)

A political scion and her magically bound fire warlock must face their greatest fears to save the Empire from a ruthless enemy in the explosive conclusion of a spellbinding fantasy trilogy from David Gemmell Award-nominated author Melissa Caruso.
While winter snows keep the Witch Lord Ruven's invading armies at bay, Lady Amalia Cornaro and the fire warlock Zaira attempt to change the fate of mages in the Raverran Empire forever, earning the enmity of those in power who will do anything to keep all magic under tight imperial control. But in the season of the Serene City's great masquerade, Ruven executes a devastating surprise strike at the heart of the Empire -- and at 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 most devastating fire.
