Title: Petunia, the Demigod Witch
Rating: K
Summary: What if Petunia was a witch, and a demigod? She goes to Hogwarts before Lily and spends her first year learning more about her mother's realm and showing that not all Slytherin's are bigots and morons. This will come in handy when James and his dumb friends arrive and think that they can bully her because she's in Slytherin. A crossover of Harry Potter and Percy Jackson!

Chapter 1: Meeting Professor McGonagall
Petunia Evens knew that she was different from even her sister, Lily. Of course that boy, Severus, confirmed that by telling Lily that she's a witch. Petunia already knew that she was more than a witch. She was a child of Hecate! It had all started when her father told her that her mum wasn't her mum and then took her to the States where she met Chiron.
He was really nice and Petunia liked him right away. So she spent her summers at camp and then went to school in England. Of course she could tell that Lily missed her when she went away. And then, in July, a woman by the name of Professor McGonagall showed up. Petunia had just come back from camp when the old woman arrived.
She was wearing dress pants, a blue shirt, and had her hair in a tight bun.
"Mrs. Evens, my name is Professor McGonagall," she said.
"And why are you here?" Petunia's stepmother asked.
"I'm from a school for children that are different from others," she said to her, "Your daughter has her name on the roll and we want to formally invite her to study."
"And how much will this cost?"
"Nothing," she answered, "Hogwarts is a free school. The only thing that a person has to pay for is the supplies and they aren't expensive."
"I don't-."
"Let her in, dear," Petunia's father said and she moved aside to let the old woman enter.
"Is she here for me?" Lily asked, sounding excited.
"Actually I'm here to talk about Petunia Evens," she said and Lily frowned. "Don't worry, dear, your name is on the roll."
"Okay," she said, "But Tuney doesn't have any magic."
"Your sister does have magic," she said, "And that's why I'm here. How does your daughter know about Hogwarts?"
"She has a friend name Severus, who told her that she's a witch and about Hogwarts," her father explained.
"Well then Petunia can take Lily to Diagon Alley to get her things," she said and that's when Petunia entered.
"Dear, this lady is from Hogwarts," her father said.
Petunia smiled at her and said, "It's a pleasure to meet you."
"The same here," she said and then Petunia sat down. "Now your name has appeared on the roll and since you're a muggleborn witch I have to come and explain to you about your magical abilities and the Wizarding world."
"I already know about both."
"Don't tell me, Severus mentioned," she said and Petunia nodded. "Well the only thing that I can do is give you this and take you to get your things."
"Can we come?" her stepmother asked.
"Yes," she answered, "Since Lily will be coming next year."
Petunia saw her sister get excited but all she could think about was that she was finally going to see her mum's realm.
Diagon Alley was amazing and Petunia soaked it all up. Her father and stepmother had brought money but her mother told her that the goblins would take Drachma's as well. They went to change their money and Petunia managed to change on coin for a whole bag of wizard money. She saw that McGonagall hadn't noticed; which she was glad about. She didn't need her knowing that she was carrying coins that hadn't been seen in over two thousand years.
"Why don't we go and get her uniform," McGonagall suggested.
"Sounds good to me," her father said and they headed for Madam Malkin.
Though the whole thing her ADHD and Dyslexia acted up. If it wasn't for the fact that those around her made sure that she was aware of her surroundings she would have wondered off. Lily was excited about the brooms and even the potions supplies. Getting a wand turned into a nightmare, which Petunia wondered if the wands could sense that she was Hecate's daughter? Finally she was paired with a holly and oak wand, seventeen inches, with the core of a creature that Ollivander hardly ever used.
A Harpy!
Petunia decided on getting an owl. She wanted to write home anytime that she wanted and not use the school owls that McGonagall talked about. She got a tawny that was a boy that she named Perseus. They all said goodbye to McGonagall, who gave her a ticket and instructions, and then they went their own way. An hour later Petunia was in her room, changing all her books from English to ancient Greek.
"What house do you think you'll be in?" Lily asked Petunia when their parents had gone to bed.
"I don't know," Petunia said. "But I won't allow a house to make me who I am. Experiences make a person who they are, not what's on your robes."
"I agree," Lily said. "Sev said that his mum was in Slytherin but I won't care what house you're in."
"Thanks," Petunia said, grinning at her sister.
The weeks passed, with only a couple of monster attacks, and soon it was time for Petunia to head to Hogwarts. Lily cried when she had to board the train but Petunia promised to write to her when she got settled.
"Be good," her father told her.
"I will," Petunia promised and then she climbed on and the man slammed the door shut.
As she settled down she thought about everything. She really wondered how Hogwarts would take a daughter of Hecate in their mist. She really hoped that she didn't have to tell anyone the truth about what she was. Petunia spent the whole time reading Alice in Wonderland, which her mother had gifted to her. No one came to join her and she had a feeling that she was going to have to work hard to make friends.
Not like at Camp Half-Blood!

A/N: My net is going down on Saturday so I will be doing mega uploading of this story. Since this story is complete then I can do that. Also, warning, there's some blood and gore in this story.
