He Banished the Real Star Weaver

After Cassian throws her out of the Seven Towers, Seraphina refuses to explain or look back. She follows Duke Lucien to the ruined Starfall Keep, awakens an ancient star core, reunites with her former rune masters, and creates an entirely new defense system. Meanwhile, the false Star Weaver, Isolde, keeps stealing her work—until disaster forces the entire kingdom to discover who the true genius has always been.
