Ash By Malinda Lo
If you’ve ever wanted a lesbian retelling of Cinderella, then this is the book for you. This book’s Cinderella is named Ash, a young girl grieving the death of her father and enduring her evil stepmother. One day, Ash meets Kaisa, Huntress to the King, and eventually falls in love. However, Ash has already been claimed by the fairy Sidhean, and must fight to love who she chooses

Welp, I dimly remembered this but it’s Beauty and the Beast not Cinderella:
