Cinderella. And Her Twin Sister

Everyone knows the classic tale of Cinderella. The slipper, the prince, the nasal stepsisters *shudder*.
But not many know of the Cinderella who looked just like her.
Ari and Savi were best friends. Sisters. Twins. Then their mother died, leaving them with their father, who soon after marries, yep you guessed it, the evil stepmother (cue evil music). Along with her two step daughters, Bev and Chloe, they made the twins' life a living hell.
Now the twins are sixteen and in high school and everything has changed. Ari, is now popular, dates the hottest guy in school and has her stepsisters as her crew.
Savi, has one friend and her life is plain as vanilla ice cream.
Join the sisters in a tale that will change the view of Cinderella.
