Amazon book description -
In the first book of an epic futuristic fantasy trilogy, this is the coming-of-age story of Reza Gard, a young boy of the Human Confederation who is swept up in the century-long war with the alien Kreelan Empire. Nightmarish female warriors with blue skin, fangs, and razor sharp talons, the Kreelans have technology that is millennia beyond that of the Confederation, yet they seek out close combat with sword and claw, fighting and dying to honor their god-like Empress. Captured and enslaved, Reza must live like his enemies in a grand experiment to see if humans have souls, and if one may be the key to unlocking an ages old curse upon the Kreelan race. Enduring the brutal conditions of Kreelan life, Reza and a young warrior named Esah-Zhurah find themselves bound together by fate and a prophecy foretold millennia before they were born.
