When the children of villains arrive from the Isle of the Lost to attend Auradon Prep, Seraphina “Sera” Ryder—the daughter of Rapunzel and Flynn Rider—should be welcoming them like every other hero’s kid. But with her best friend being the daughter of Hades, Sera finds herself drawn to the chaos of the Isle and the world of Mal and the villain kids instead of Auradon’s perfect rules. As the line between good and evil begins to blur, Sera starts to wonder if she really belongs in Auradon at all.
