Daughter of No Worlds (HB) - (1) The War of Lost Hearts

From the author The Serpent and the Wings of Night! A life in slavery taught Tisaanah how to survive with nothing but a sharp eye, a quick mind, and a touch of magic. But the night she tried to buy her freedom, she nearly paid with her life. Instead, she murdered the most powerful man in Threll. Forced to flee, she has only one chance at saving those she left behind: pledging herself to the Orders, an organization of magic Wielders strong enough to destroy her former masters. To earn her place, Tisaanah is forced into an apprenticeship with Maxantarius Farlione, a handsome and reclusive fire Wielder who despises the Orders. He has no interest in helping her. But as the Orders' grip tightens around them both, his bloody past may be the key to her future ... or their downfall. Under looming war, Tisaanah must master her magic and survive the Orders' demands. And as her feelings for Maxantarius deepen, she is forced to decide how much she is willing to trade away for revenge. The Orders have bigger plans for Tisaanah. Darker plans. But Tisaanah will stop at nothing to save those she abandoned. Even if it means forfeiting her freedom and sacrificing her heart. Even if it means wielding death itself.
