Kai Kinsley doesn't realize he's been carrying starlight in his veins his whole life. Just after his tenth birthday, when he steps into the Astralis Festival and is connected to his celestial Lineage, everything changes. A HALO is forged. Power awakens inside him and the doors of Astralis Academy open, welcoming him into a world where magic is inherited, not chosen. But Kai didn't come to Astralis for glory. He came for his father, missing and whispered about like a cautionary tale, last seen within the Academy's walls. As Kai begins his first year alongside new friends and dangerous rivalries, one question follows him like a shadow. What, exactly, is he? A Legacy of stars… planets… moons… or something older and stranger, hiding in the dark between constellations?
