Awakened, She Rises as the Frost

In the city-state of Os, magic is forbidden to women, and those who practice it are sentenced to the pyre. Callista, a gifted frost mage who secretly learned sorcery as a child from her aunt Ledia, has spent fifteen years hiding her sex by posing as a man at the Academy of Magic. When the ruthless Lord Hethias of the Flame Clan ignites a war between clans, he ambushes her father Damon and wipes out the Severu bloodline, pulling Callista into a fight against the enemy who destroyed her family.
