Synopsis

About I Want to Escape from Princess Lessons

Leticia Dorman is living every girl’s dream—she’s the daughter of a duke who’s grown up in the lap of luxury and she’s engaged to none other than the handsome crown prince, Clarke. But this dream is her nightmare! In preparation to become part of the royal family, Lettie has endured ten painful years of lessons on everything from dancing to etiquette. Her only chance of escape lies in the prince breaking off their engagement, which seems unlikely…until he shows up at a royal ball with a mysterious woman. This could be her chance to break free, but not if Prince Clarke has anything to say about it! (Source: Seven Seas Entertainment)
