Story Note: This is a canon-divergence AU story. Neither Harry OR Percy will be OP, and neither of them will be 'hybrids' or 'Mary Sues' or anything similar. THEY WILL NOT BE INVOLVED WITH EACH OTHER'S STORY (I had to add that in after a guest gave me a lengthy review about what I could do next). Dumbledore has his canon, slightly manipulative but well-meaning personality, Sally is the best and Poseidon is slightly more involved in Percy's life later on and Harry is way more smarter than in canon, because why not?
Chapter 3
Harry woke up first thing in the morning, more excited than he had ever felt in his entire life. It was the 24th of July. Which, of course, meant that it was the day that his Hogwarts letter would arrive. Harry knew all about it, of course, thanks to his Aunt Sally telling him everything she knew, down to the little details of his mom's excited expression when told Aunt Sally about receiving her letter.
"Morning, Harry!" Percy said brightly with a huge grin when he saw Harry in the kitchen. "Mom told you to set the dishes– She gave me permission to make blue pancakes!"
"Well," Harry quipped, "I hope you're careful with the butter— we don't want a repeat of the last time you made pancakes, do we?"
Harry remembered the last time well— Percy tried to make pancakes, and accidentally dropped a whole stick of butter into the fire. In less than a minute, it bursted into flames, and the stove was effectively broken. The blutter exploded everywhere, and it was only thanks to Harry that an invisible bauble of air formed around them and solidified, causing the butter to simply slide down.
Percy pouted, "Mom brought a non-stick pan. Didn't let me use butter at all !"
Harry laughed. Butter was, in Percy's opinion, the most vital ingredient to making a pancake taste good— after the endless amount of sugar that he'd put in, of course. "C'mon. I'll help you with your pancakes."
Percy shook his head. "Nuh uh. Mom told you to set the table. And I wanna make the pancakes by myself."
Harry rolled his eyes, but took out the plain white plastic plates, and placed it on the table. He pulled out the forks and the knives, discarding it all inside a ceramic mug. "Fine. But if you're burning it, it's all your fault."
Percy gave a pause at that, but he had already poured the batter in, the pan sizzling hot and making a slight fizzing sound the moment the batter came into contact with the pan. "Yeah, but isn't it also your fault for not checking on me, right?"
Harry was tempted to strangle Percy. As much as he loved his little cousin, he was more than frustrated at times with him. His ADHD acted out in the most inopportunate times, sometimes in the middle of cooking, others when getting to bed, and the worse and most frustrating for Percy, in class. It wasn't just that however, his cousin was particularly snippy and snarky, which of course, got on Harry's nerves at times.
"Shut up, you buffoon," Harry muttered. He went over to take out another pan, placing it next to Percy's pan and turning up the heat. "By the way, where's Aunt Sally?"
"Mom went to the grocery store," Percy said with an unmistakable excitement to his voice. "She said she's going to buy the ingredients for… well, you know… your cake ."
Ahh… yes. The cake. For his acceptance to Hogwarts. Which, now that he thought about it, should be arriving soon enough. He hoped Aunt Sally would be back before it arrived, so they could open it, and celebrate it together.
Suddenly, the doorbell rang, and Harry quickly killed the fire, disappointed he wasn't even able to pour the batter. "I'll get it," he said, making way for the door. As expected, it was Aunt Sally, with two large grocery bags in her arms and a large smile on her face.
"Harry!" Aunt Sally exclaimed the moment she saw him. She pulled him into a tight hug, which caused the rather heavy grocery bags to hit his back. "Good to see you up and awake! Did you get the letter yet?"
Harry shook his head. "Not yet. It's fine anyways, since I was hoping we'd get it together."
Aunt Sally ruffled his head. "Well we better go in before Percy makes a mess out of the pancakes."
Indeed, Aunt Sally was right. A few minutes or so later, they would've been eating burnt pancakes. Harry ran to the stove as quickly as he could, lifting the pan off the fire, and turning off the gas. "Percy!" Aunt Sally gasped, prying the pan from Harry's finger to dunk it into the sink. She turned the water, hot steam rising as soon as the cool water came into contact with the hot pan.
"What happened?" Harry asked, turning to his cousin. "I was gone for less than five minutes!"
But Percy wasn't looking at him. He was pointing at something behind him. Harry quickly turned to the direction that Percy was pointing to, blinking owlishly when he saw what was in front of him.
An owl. A freakishly huge owl, with brown widespread wings that was littered white and black, and an envelope clutched in its talons. With each flap of those wings, it bumped into the windows, muted sounds of its squawking easily heard.
"An owl!" Percy exclaimed. "That must be your letter!"
Eager and excited, Harry rushed to unlock the window, letting the owl fly in. It circled the kitchen once, twice and thrice before squawking for a final time and letting the letter drop. Harry picked the letter from the floor, his hands shaking as he held the envelope.
"Well," Aunt Sally said with a smile, "Go on. Open the letter."
Harry cracked the seal –a nice seal that had four different animals on a coat of arms, clearly meant to represent Hogwarts' four houses– and pulled out several sheets of paper.
"Lemme see!" Percy said eagerly, jumping over the chair that was between them. Despite his dyslexia, Percy squinted at the text, frowning when he failed to read. "Mom, mom, read this out for me!" Harry laughed at his cousin's excitement. Percy seemed to be even more excited than he himself, which was hard to achieve, considering how hyped Harry had been for his letter.
"Now, Percy," Aunt Sally said, "This is Harry's letter, he should get to read it first."
Percy handed it to Harry who was just as anxious to read through it. The first page was the much expected acceptance letter, saying:

Harry handed Aunt Sally the letter, and checked over the second page, which he found was even longer than the first.
"Can you check out the second page?" Percy said once Aunt Sally finished relaying to him the contents of the letter. "I wanna know what cool stuff you're gonna bring!"

"Does that mean we're going to Diagon Alley tomorrow?" Harry asked his Aunt, who had told him countless stories about the place from when his mum brought his aunt there with her.
Aunt Sally smiled indulgently. "Yes, I suppose we are, aren't we?"
Then Percy cut in— "What about the cake? Aren't we going to have a cake?"
"We're going to have that too," Aunt Sally reassured.
Harry grinned. "I wanna make the frosting!"
Author's Notes: Has it been FOREVER since I touched this fic? Yes- it has. Am I absolutely guilty? Yes I absolutely am. FUN FACT: If you use or read AO3, this was updated around May or July? Well, one thing turned to another and as I was about to orphan my old works... I orphaned this as well. Safe to say I was panicking on how to fix the situation for over two months at this point. So uhh... yeah. That's the entire reason why yall have YET to get a single bit of writing from me, basically. On the bright side, I MIGHT be updating this fic soon? Maybe. If I don't I'll definitely tell all of you my plans!
