The Giant war is over and Percy Jackson is spent. Finally there's a chance he can be with Annabeth for a while and he eagerly awaits the summer they have planned together. But when Hecate shows up and sends Percy on a new quest, it could be the by far stupidest thing he has ever done. He must be the new teacher at Hogwarts. Harry Potter has been attacked by the Ministry and Dementors. If that wasn't enough he now has a new teacher. But he is like, a 17 year-old kid. Who looks a lot like him. It's Harry's 5th year and he is now a nutter to the wizarding world. So when he sees the kid show up at Number 12 Grimmauld Place, he starts thinking he might actually be mental. The new kid turns out to be a teacher. The teacher of DADA. But Umbridge is still there- as the High Inquisitor. It seems she watches the new teacher-Professor Jackson- a lot more than the others. Something is off about him. And the Golden Trio always tries to find out what.

When the Seven, Thalia, Nico and Clarisse are asked to go on a quest to Hogwarts, to befriend a few wizards, the golden trio and their friends to be exact. But the golden trio are suspicious of this new bunch.... they're not normal wizards. Will the demigods be able to keep their secret or will the golden trio find out? Disclaimer** I do not own the Characters!! Just the plot!!! Some of the plot I have inspired off other people. The characters belong to my favourite people in the world: Rick Riordan and J.K Rowling. Without whom my life would consist of me sitting on my bed crying all day. [ I promise will finish this story, but entering my last years of school is very time consuming. But I will finish this!! Additionally, each chapter is written sort of like an episode, they're connected but in small details as building blocks. Only the last few chapters will be heavily connected and left on cliffhangers. But, as far as the story goes now, if you read it as is you won't be hanging on for anything. ]

Harry and his friends are back for their eighth year at Hogwarts. Only this time there's four exchange students from America that seem to know Draco and Snape. Not only that, but a new American DADA teacher who's pretty much their age. Even worse, he also seems to know Snape and Draco. Sigma is teaching at Hogwarts in an undercover mission to keep Harry safe from a new and dangerous threat. Oh yeah, Will, Nico, Zac, and Luke are there, just to make things worse. ~*~ *this isn't edited (not yet at least) *sometimes there will be strong language *I don't own the PJO or Harry Potter characters and stuff like that ~*~ Book 1: Son of Chaos (Rewritten) ✔️ Book 2: The Harry Potter Protection Program ✔️

"So... Thalia... why are you even on this quest again?" "I'm here to kill a dragon." "Oh... that's... nice." Come join the adventure Percy, Annabeth, and Thalia are having as they venture to Hogwarts! Facing dragons, Dark Lords, and most dangerous of all... Potions Class with Snape, will these demigods succeed in protecting Harry Potter? And what might they find along the way? A certain Son of Hades perhaps? Long lost secrets?

Percy just wanted some peace and quiet. He finally defeated Gaia, the world is normal...but the fates, as usual, have a different idea. Percy, Annabeth, Jason, Piper, Thalia, Leo, Nico, Hazel, and Frank have to play bodyguard. For who, might you ask? Someone special. Someone who is going to need help, since his worst enemy has returned, bringing one of Percy's along for the ride. Who is this kid? Why, Harry Potter, of course! ***As you can tell, I don't own Harry Potter or Percy Jackson, props to those authors for actually coming up with the idea! I do have a few OCs but that's it!***

Yay, a bandwagon that is so full I'm surprised it hasn't collapsed yet. Or maybe it has, either way, I'm gonna have some fun with this story. So yeah, Harry and the others find out Voldemort has a grandson and have decided to take him to Hogwarts yada yada yada already been written, whatever. And now Percy has to deal with more crazy shenanigans. I am continuously editing and changing things from past chapters. If there are any spelling, grammar, or plot mistakes TELL ME. Even if a sentence sounds weird, comment how it might sound better. The cover art(minus the text) is not mine, I found it on Google images, it belongs to whoever it belongs to.

A nice, relaxing, day at the beach; a romantic movie and dinner with Annabeth. Those were my plans before Gandalf's twin, mini me, and a couple others arrived at my door, asking for Perseus Riddle. Now I have to go to some school named after a pig's disease. There goes my plans; stupid fates. -Cliche ends some time after Percy gets to Hogwarts. -Takes place during The Order of the Phoenix and after The Blood of Olympus, although at times, the time and parts of the story don't match up. -Cover credits go to AdastraelGenesis. -Chaos is involved in this book, although the story doesn't revolve around her. That being said, PLEASE READ, and read a few chapters before actually judging. It's not that great in the beginning but gets better, and then becomes not that great at all, but then becomes really awesome. BUT if you're one of those rude people who need every single thing to match up with the books this is based on, and get annoyed when people are out of character, well then...bye, bye! *ranked second for persassy* This is what some of the readers say: "Amazing like always. Gosh I love your story. I think it's literally the best HP/PJ Story I've ever read. And I've read a lot of them. PLEEEASE Update soon." -Epulary "Can I vote 10000000000000000000000000000000000000000000000000000000000000000000000000000090000000000 times?" -Cupcakelover3232 "I had to stuff a pillow in my face I was laughing too hard." -justafellowtrash Also, if any of these people who commented see this, thank you so much. :)

I'm bad at summaries so please just try and read this. Percy Jackson goes up Hogwarts (hence the title) undercover and find out how it goes. This is only a short story so don't expect millions of chapters or anything. I made the cover, yay! (I do not get the point of these) I am not a middle aged man people. I am a teenage girl. I am not the author of these marvelous characters. I write FANfiction...and sometimes fiction but not in this story! The characters belong to the amazhang Rick Riordan and the wicked J. K. Rowling! This was my FIRST book, so if you read my other books you'll understand how this book isn't by best work, BTW

The gods have Percy and Nico help the world that is unknown to demigods. The Wizarding World. Percy is changed into his fifteen year old self so he can fit in, and him and Nico are sent to help stop the war against Voldemort before it even starts. (This takes place after the Giant War and during Harry Potter's fourth year at Hogwarts. You really shouldn't read this if you don't like Percico.) *Art by Viria and cover made on Moldiv app*
