The Boy in the Emerald Fire by C A Jackson

In a world where magic is hoarded by nobles, one commoner becomes the spark that could burn it all down.

Lorian Night is a blacksmith's bastard with no claim to power-until a noble's magic accidentally fuses with his soul. The theft is impossible. Illegal. A death sentence. Forced to pose as the noble's heir, Lorian is swept into a deadly journey to the capital, carrying secrets that could shatter kingdoms. As war brews and the line between justice and vengeance blurs, Lorian must decide what kind of man he wants to be: a pawn of the elite, or the hammer that forges a new order. But power, once stolen, never comes without cost.

The Boy in the Emerald Fire is a gripping fantasy of class rebellion, forbidden magic, and a young man's fight to define his fate in a world built to keep him down.
