Rise of the Mages (The Age of Ire, Book 1)

Emrael Ire is a student of war with lofty ambitions, despite being so poor his boots are more hole than leather. He and his talented younger brother Ban work hard to build themselves a better life at the Citadel, a school that specializes in both infusori Crafting and military arts. Their lives are upended when the power-hungry Lord Governor of the neighboring province invades the school with the help of a sinister sect of priests devoted to the newly awakened Fallen God of Glory. Many of the infusori Crafter students are captured—Including Ban. Though Emrael stands little chance against the Lord Governor and his armies, he’s desperate to save his brother—even if that means accepting the help of allies with uncertain motives, or becoming a practitioner of a forbidden magic. There is nothing he won't sacrifice to save his brother, but what happens when the cost of success is not his to pay?
