Blood scion

"Fifteen-year-old Sloane can incinerate an enemy at will--she is a Scion, a descendant of the ancient Orisha gods. Under the Lucis' brutal rule, her identity means her death if her powers are discovered. But when she is forcibly conscripted into the Lucis army on her fifteenth birthday, Sloane sees a new opportunity: to overcome the bloody challenges of Lucis training, and destroy them from within"--Provided by publisher.
