The only thing Orla fears more than her enemies is her own power. Fleeing the destruction of the Palace, Orla and Ged have begun a perilous journey. Ged must face for the first time what it truly means to be the son of the King. Orla burns with a secret that might destroy them both. Together, they seek an uncertain safe-haven on Koralis. Known as the Grim Isle, Koralis is a place of dark legend. The reality will prove to be darker still. The signs of Darkfall are all around them: in the oceans, the Mer are waking; deep within caverns of stone, dragons stir. And with the return of magic to the world, Orla's power too is growing. With danger all around, they must each draw on their deepest strengths to survive. But what will they do when they discover the greatest danger they face is the one they can't outrun?
