In the worlds of Harry Potter and Percy Jackson, Harry is eating dinner in the Great Hall and Percy is being chased by monsters. How do the two worlds meet? Simple. Percy falls through the enchanted glass ceiling of the great hall unconscious. Percy doesn't know where he is, only that he's being chased by monsters. Fighting in the sky with Blackjack, there are only two monsters left. The monsters hit Blackjack and Percy with their clubs upside the head, rendering them unconscious and spiralling in different directions. As Percy plummets downwards, Riptide slips out of his hand and slices through the two remaining monsters, killing them out of pure luck. Or is it pure luck? When Percy wakes up in the Hogwarts infirmary and tries to leave, Hecate tell him to stay and protect the Boy Who Lived and his two closest friends. Except how is he supposed to protect people that don't trust him? Disclaimer: I do not own PJO, HOO, or HP.

What happens when Nico is sent to teach at Hogwarts? Will his cover be blown? Will he succeed in teaching the witches and wizards what they need to know for the battle to come? THERE IS TRIGGERING SELF HARM CONTENT

The war was over. At long last, Voldemort was dead, and this time, he won't return. Unfortunately, those who were attending Hogwarts during the war were unable to learn anything. So of course, when Hogwarts sent all those students letters offering to have the re-do their previous year, everyone jumps at the chance, all of them thinking that they would finally have a peaceful, or at least uneventful, year at Hogwarts. It wasn't one. Perhaps Draco Malfoy was partially responsible for that. Perhaps the year was doomed to be chaotic from the day it began. Or perhaps the Fates had a grudge against everyone who chooses the path of a hero. DISCLAIMER: I DON'T OWN PERCY JACKSON OR HARRY POTTER!!

Sally isn't who she think she is, she thought she was a average muggle, pregnant with her first child, by Poseidon, and just Poseidon. No, it was all a lie. She finds that out one night when she comes home to find Percy half to death on her living room floor getting beat, again by the man she married to protect him. She's isn't Sally Jackson, she's Lily Potter neé Potter. She has another son, Harry, a year older then Percy, and Percy has two father's, strange but true. She remembers everything. And she's getting ready to go back. For Harry, for Percy, and for herself. **** Sally is not the main point in this, Percy is. And Harry. Crossover of course as you can all tell. Yaoi, Boyxboy ships will be in this, no Percabeth. And definitely no Hinny. I hate Ginny to be honest. Also OOC, and Soulmate Au in a way. DISCLAIMER: I own nothing but the plot. Not all, just my own mixed in. Now, go and enjoy!!!

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. *

Percy Jackson, a demigod well known. He just came back from his battle with Gaia, still shaken up from the experience. One day, he came back to camp only to see Chiron asking him to go to a quest. Chiron wants to know if the wizards can be allies, but one problem. Voldemort is still alive. He came back after escaping death again, tricking the God Hades, and in the process getting the God angry. Percy needs to go to Hogwarts, a school for witchcraft and wizardry. Harry Potter, killed Voldemort. He finished his last year in Hogwarts, but was asked to retake the year, since the experience affected their education. When he gets to school he meets this weird exchange student. He excels in all classes, and is friends with almost everyone. Little did Harry know that he is here to defend Hogwarts from his old enemy, Voldemort. Disclaimer: I do not own the characters, all rights go to Rick Riordan and J.K. Rowling, but the plot is mine. Cringe is on your way as well. This was written by young me Sequel: Percy Jackson ~ Death Rechained {Book 2}

This is a Percy Jackson and harry potter crossover. Percy Jackson receives a quest from Dumbledore to go protect Harry at Hogwarts I know that the time periods for each separate character doesn't make sense, so let's ignore it.

update: some chapters have been unpublished, so there may be gaps in the story This is just a small free-write thing that I am doing. Demigods from both camps are sent to a wizarding school to defend the school against the rising threat. Will the heroes succeed in their quest? Or will they fall to the hands of evil? What will happen to the demigods at Hogwarts? This is my first story, so sorry about any mistakes.

Ok in my opinion this whole book is a mess, I can't say its a work I'm proud of and for that reason am currently working on a rewrite. Other people have told me they love this book and its really so feel free to read and if you have a suggestion for my rewrite feel free to comment it or pm me now heres the descriptions Magic people, wizards and witches they call themselves. Apparently those are real. Of course they are and why wouldn't they needs us as soon as I was going to get a break. Just that special demigod luck I guess. So off to Hogwarts!
