Her counterpart: Kael Ardent, the scarred emissary whose dragon fire saved the capital but cost him his clan. Political sabotage sparks riots, forcing Raya to anchor Kael’s smoldering rage with late-night lab experiments and rooftop flights that melt the skyline. To prevent war, they must fuse logic and fire—and decide if love is the ultimate peace treaty.
