She Is the Dragonfire

Gifted mage Eleanor Ironwood is forbidden from magic by her father. After her sister’s murder, she flees with her mother’s sacrifice and trains under Archmage Godwin for six years. Amid a siege, she comes back to find her family brutalized. With Godwin’s sacrifice, she reaches Ninth-Level power, summons the Primordial Dragon to destroy her foes, and claims dominion over House Ironwood and Aldoria.
