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

Percy was looking forward to some down time with his girlfriend Annabeth after the Giant War ended. What he didn't expect was an old man claiming that he was a wizard. If that wasn't enough, it turns I out that he's not just any wizard, he's the grandson the the dark lord, Voldemort

Only one of the seven survived the war. Percy Jackson. After Annabeth dies, he's broken. Not the same seaweed brain as before. He returns to his apartment, to find his mom, and Paul dead. killed by one of Gaea's minions in revenge. He finds out that his mom had a sister. Petunia Dursley. ~ when aunt Petunia enters the house with a strange boy, Harry doesn't know what to think. He knows this boy is hiding some secrets. but will Harry find out what they are? I DO NOT OWN ANYTHING. ALL RIGHTS GO TO RICK RIORDAN AND JK ROWLING

[3] Reconciliation: ON HOLD INDEFINITELY :( Last year, Perseus Jackson discovered that he was a demigod. His father was not some ordinary man as he had originally thought. Instead, he was the son of the one and only Poseidon, the Greek god of the seas. However, his adopted brother, Harry Potter, had no idea about Percy's true parentage. The Headmaster of their school, Hogwarts School of Witchcraft and Wizardry, had forbidden Percy from telling anyone. Thus, he was forced to go to America, where he would be safe during the summer outside of school, without telling anyone where he was really going. Percy leaving made Harry angry and resentful. After all, he would be forced to spend the summer with the abusive Dursleys while Percy went off and had fun in another country. However, when Percy returned to school to join his brother and friends, he found out that his brother was in grave danger. An infamous mass-murderer by the name of Sirius Black had escaped Azkaban prison. And he was out for blood. DISCLAIMER Note that I do not own anything that was created by J.K.

Another note, I edit as I go along so there may still be some grammar and spelling problems.

[1] New Beginnings: WARNING!! Story is technically complete but I started editing literally years ago then never finished so the beginning's a little funky! Percy Jackson was adopted at the age of seven by the nastiest family in the world: the Dursleys. He met Harry Potter, the most wonderful person in the entire universe, that same day. Though completely unrelated, the boys were nearly identical, a connection forming between them that would last years to come. The pair would go through life as brothers in everything but blood. Connected at the hip, these seemingly average boys had much more in store for them than they could ever imagine. A note: Percy Jackson doesn't discover anything about the demigod side of his universe until later in the second book. Just a warning. If that's too slow for you, don't read. DISCLAIMER Note that I do not own anything that was created by J. K. Rowling or Rick Riordan. I only own some of the plot and the occasional person or place that I may create myself. WARNING When people comment mistakes, I come back and I make sure that they're fixed. So, I'm still editing.

Harry has a little brother

PJO x HP Percy Potter is the forgotten brother of the infamous, Harry Potter. Percy Jackson's father is a Greek god and had left when he was born, and his mother died only moments after giving labor. Lily and James Potter thought they couldn't have a child. They had tried many times before but have failed. They came across a certain sea green eyed boy in an orphanage, and adopted him. But only a month later they found out Lily was expecting. Harry was born and the two baby Potters were loved equally. Friends of Lily and James were astonished by their similar appearance and the boys were often mistaken as twins. One Halloween night, Lily and James went out to a Halloween party and left the boys with a babysitter. The Dark Lord of the wizarding realm, came to their home hoping to rid the child destined to be his downfall according to a prophecy. He killed the babysitter and went upstairs to finish the job. But he found two children in the room and decided to kill both. Both Harry and Percy were hit with the curse but the curse on Harry repelled because of the power of love from Lily and the spell did not harm Percy for he was a demigod. James and Lily returned home and found their home a mess but their boys safe. Dumbledore, the leader of the Order of the Phoenix, came to the Potters' home along with the wizarding press. Dumbledore told the press and the Potters that Harry had been hit with the killing curse and had survived thus the lightning bolt scar. Papers were printed and sold throughout the wizarding world; "THE DARK LORD GONE!" and "THE BOY-WHO-LIVED" Nowhere in the papers was Percy mentioned.

Percy Jackson comes to Hogwarts after given a Quest, that Albus Dumbledore and Chiron have agreed on. He is a teacher for a new subject, Muggle Fighting. Despite nobody knowing he was preparing them for an ultra war, which will unite the DemiGods and Wizard/Witches. Harry Potter is in his fifth year of Hogwarts. Things are at the beginning of the approaching war. He hears about a new subject that every fifth, sixth, and seventh year is required to take. He wonders who the professor is, and more importantly, why they needed it. *Disclaimer I don't own any of the characters. All thanks to Rick R. and J.K. Rowling. *

I couldn't believe it. I didn't want to believe it. So I pretended it didn't happen. But it did. In saving me from Medusa, the love of my life, Percy Jackson, was turned into gold. Yep, you heard right. Gold. The legend goes that there is a hero renown throughout the worlds. A hero that would sacrifice himself to save an innocent. A hero with strength, integrity, kindness, and a heart of gold. And it would be his undoing. It has become race against the clock. Once it starts to tick, we have little time to piece together the puzzle and find the elixer before the clock strikes and I lose him once more. This time, forever. DISCLAIMER: This is the disclaimer for the whole book. I don't own any Percy Jackson/Heroes of Olympus characters (If only!). Rick Riordan does (Lucky him!).

(This is the third book in the Too Strong series. Too Strong, and Stronger Than You Think are the first books. I suggest you check them out before you read this one) Achilles and Andromeda Jackson have no idea who they are. They can't remember anything before they came to camp. And everyone at camp claims they don't know who they are, but Ach and Andro have a feeling that they're hiding something. The camp leader, Annabeth Chase, daughter of Athena seems to hate them. But why would she hate them if she doesn't know who they are?! When Ach and Andro begin to have dreams of someone from a distant memory, and Rachel the oracle gives them a prophecy, the two twins, along with Leo Valdez, go on a wild goose Chase in hope to find out who they are. But of course, it won't be easy. With the gods, monsters, and Tartarus himself trying to stop the broken family from reuniting, hope is very slim for the Jackson family. And with Andro and Ach gaining their memory little by little, the fact if they even what to save their family is in question. The the title goes to @LunaLilyPotter and the cover goes to @funnierthanu. Thank you both.
