Warrior by Janna Lafrance

For nearly two generations, the world has been free from war, from religion—and from freedom. A remnant of believers of the ancient god, Bära, has arisen. They have been awakened and are experiencing supernatural power never before seen. They are hunted, tortured, and killed—yet they grow stronger. One man has been chosen to lead them, whose passion is not for power. He must choose to follow his desire or to trust an unlikely path and become: the Warrior.
