My New Sister

Noelle Hartman is a high school outcast who'd rather spend her Friday nights reading about feminism then going to a party. She's finally content with her life, at ease her moody sister and flirtatious mother, when everything suddenly changes. Her mom meets a new guy, one she keeps around for more then a week. Out of nowhere, the couple decide to live together. So now Noelle and her family are moving into a fabulous house, but who already lives there but Noelle's biggest annoyance -- the peppy, trampy head cheerleader. Noelle can't believe her misfortune, but she soon finds out that there's more to her new sister then meets the eye, and she may even make a friend in her.
