Brynne Calder has spent her life in a forge at the edge of the world, hammering iron beside a father who never says her mother's name.

Then the king's riders burn her village looking for a girl with a scar shaped like a crown.

By dawn, Brynne is running with a band of outlawed knights, a dead rebel messenger at her feet, and one impossible truth in her blood: she carries the lost dragon-oath of the Fallen Realm, the shattered kingdom the crown erased from history.

The rebels want a symbol. The exiles want a queen. The king wants her alive long enough to chain the last dragons to his war.

But the deeper Brynne is dragged into the uprising, the worse the truth becomes. Her mother was no martyr. She was one of the architects of the old realm's destruction. And the prophecy now gathering armies around Brynne may not promise salvation at all. It may be a map back to the same fire that ruined the world the first time.

To break a tyrant, Brynne must decide what to inherit: her mother's guilt, the rebels' hope, or the dragons' hunger.
