Dragon Bones by D.K. Holmberg

Dragons have been gone from the world for centuries, though their power remains.

A war fought a thousand years ago removed the destructive threat of dragons, allowing fire mages to use the magic stored within their bones to protect the empire for a millennium. The empire has known a fragile peace, held together by that ancient magic.

When Fes is discovered by the emperor’s chief fire mage, he’s given a chance to use his particular gift for gathering lost dragon relics to become something more.
