Chapter 1: Birthdays Approaching

Y/n Dursley is Dudley's older twin sister. Unlike her brother she has taken a liking to Harry and considers him another brother.

She brings him meals when he isn't allowed any, and she is nice to him unlike her relatives. Her family thinks it's because she's nice to everyone but that's not true she genuinely likes Harry.

When it is revealed that she along with Harry are Wizard and Witch and are attending Hogwarts what will happen? How will her family react? Will she last at her new school? Will she find out a secret that her parents have been keeping from her her whole life?

Obviously I don't own Harry Potter all rights to J.K. Rowling.
