Union of Renegades by Tracy Falbe

"He felt ill when he considered that he had helped to make the Empire bigger."

Thoughts such as these prod Dreibrand Veta to make a fateful decision when he reaches a mythic Wilderness.

He has killed for his country to get to this point. At the front lines of imperial expansion, he hoped to rebuild the fortune of his noble family, but he will have to go farther. In his daring travels he encounters the rys, a race far more powerful than the human empire that bred him. Dreibrand cannot defy the rys Queen Onja nor defend his companion, Miranda, and her children from the wicked tyrant Queen. Desperate for help, Dreibrand and Miranda join Shan, a rys with emerging powers who plans to challenge Onja. In Shan's pursuit of the rys throne, he exerts his magical powers, gathers his allies, and incites rebellion among Onja's human subjects. Great wealth and power will reward the kings, warriors, and spies that align themselves with the rys pretender, but defeat could mean worse than death. Onja can imprison souls and her genocidal rage is legendary. Everything is at risk for Shan's union of renegades.

In this opening novel of The Rys Chronicles you'll meet a man scarred by bad deeds who answers the call of a heroic cause. An unconventional heroine will tug at your sympathies as she bravely faces adversity with all the strengths and vulnerabilities of her womanhood. And overarching it all are the rys. Their magic makes them superior to humans, but they are not above employing humans in their deadly schemes.
