Gwendolyn, the youngest of the King's three daughters, is living proof that princesses don't always have it all. She isn't like a typical fairy-tale princess, or other princesses in the Pastel Kingdom. Gwendolyn, with her big heart and love of baking, isn't particularly attractive. Unlike her sisters who have woodland creatures do their hair and makeup, or have flowers blossom wherever they sleep, Gwendolyn is a bit...different. So when her father proposes marriage for her and her sisters to make an alliance with the Plaid Kingdom, it breaks Gwendolyn's heart to hear that Prince Fredrick thinks she's "really ugly." Overwhelmed and ashamed, she runs away into the forest and encounters the twisted world of the Cursed Princess Club, where her life will never be the same.
