Embers: Book One of the Ascension Saga

Aleksander awoke to a world on fire with only one clue to his forgotten past: a fresh scar of his name carved into his arm. After discovering the ability to create fire from his hands, he was captured by a race of winged beings called Sangorans; their master, High King Valistaran Talohir, plans to end the war between Talohira and Thanatanos forever. But when he is finished, will anything remain?
Now Aleksander and his only ally, a warrior by the name of Shanthah, must fight to survive in the brutal Talohiran slave camp. However, even with the power to create fire, escape seems impossible. One prisoner in particular, a young woman named Mara, appears to hold a key to Aleksander's past, but may also be instrumental in saving his future. Even if they make it out alive, they will learn one terrifying fact:
The world is on fire in more ways than one.
