Petunia Evans had a sister who was a witch. Sometimes it was hard for Petunia to not feel jealous of Lily. Lily was the perfect one; the youngest daughter and she had magical powers to boot. Petunia sometimes felt overwhelmed with jealousy especially when the family heard that Lily had been invited to a special school for witches. When Lily left Petunia was miserable. She missed her sister so much her jealousy vanished completely and throughout their school years the two sisters wrote letters to each other every single day.

At school Petunia had a very good friend whose name was Thomas Granger – Tom to all his friends. Tom asked Petunia to go to the movies with him the summer before their last year of school and when they left he proposed. He was going away to university to study dentistry and didn't want to lose the best friend he'd fallen in love with.

That summer two weddings took place, the first between Thomas Samuel Granger and Petunia Angela Evans, then the following week Lily married a wizard she had met at school by the name of James Potter.

About two years after the two weddings had occurred, Petunia discovered that she was pregnant. Three months later, Lily discovered she was also having a baby. Petunia had a little girl whom she called Hermione and Lily's son was given the name Harry. A few days after Harry was born Petunia received one last letter from her sister.

Dear Petunia,

Harry, James and I are in great danger and have to go into hiding. I hope it won't be for long. I love you so much and I'm sure I'll see you soon.

Always yours,

Lily Potter

This letter was the last thing Lily would ever say to her sister. It was about a year before petunia heard anything more about Lily Potter. November 1st that year brought with it a surprise. Opening the front door that morning to fetch the milk Petunia had the biggest shock of her life – her one-year-old nephew was asleep in a basket on the doorstep, a letter clutched in his hands. The letter's contents told Petunia that her sister and brother-in-law had been murdered by an evil wizard, who had then vanished, the previous evening.
