The Ugly Stepsister (Unfinished Fairy Tales, Band 1)

When Kat accidentally rips apart an old picture book, she's magically transported into the world of Cinderella--as Katriona, one of the ugly stepsisters! Life turns upside down now that she's a highborn lady and must learn how to survive the social season, including how to get through the door in a huge metal hoop skirt. To get back, she'll have to complete the story, right to the end of happily ever after. But the odds are huge: the other stepsister is drop-dead gorgeous, the fairy godmother is nowhere to be found, and the prince, despite being insanely hot, openly dislikes balls. Can she ever return to the modern world?
