After eight years of devotion, Sera discovers her fiancé Cedric has given her bridal dragon to her adopted sister, Dahlia. Betrayed by her family, framed for poisoning dragons, and brutally punished, Sera finally breaks their engagement by walking barefoot across burning coals. Cedric mocks her, asking who would ever marry her now. Then a hundred dragons descend from the sky, and Alaric Frostmoor, the feared Dragon King of the North, arrives to claim Sera as his bride.
