But when a deadly competition thrusts her into the heart of a war for humanity's survival, secrets of her father's past begin to surface, forcing her to choose: fight for the light or be consumed by the darkness. In a world where entire cities can burn in minutes, can she protect her mother and sister-and uncover the truth before it's too late?
