Castillo Torres, Student Body Association event chair and serial planner, could use a fairy godmother. After a disastrous mishap at her sister's quinceañera and her mother's unexpected passing, all of Cas's plans are crumbling. So when a local lifestyle-guru-slash-party-planner opens up applications for the internship of her dreams, Cas sees it as the perfect opportunity to learn every trick in the book so that things never go wrong again.
The only catch is that she needs more party planning experience before she can apply. When she books a quinceañera for a teen Disneyland vlogger, Cas thinks her plan is taking off...until she discovers that the party is just a publicity stunt and she catches feelings for the chambelán. It's clear that her agenda is about to go way off-script, and that real life is a bit more complicated than a fairy tale. But maybe Happily Ever Afters aren't just for the movies and a little spontaneity is just what she needs. Can Cas go from planner to participant in her own life? Or will this would-be princess turn into a pumpkin at the end of the ball?
