Forth year at Hogwarts is hard enough, but with the triwizard tournament practically impossible the add in 4 demigods and now heres trouble. Percy, Annabeth, Thalia and Nico have been required by Dumbledore to protect Harry Potter from danger while disguising as wizards. But what happens when a 5th name pops out of the goblet that night, what happens when the name is Percy's? Let's just say there will be drama, adventure and love.

Harry Potter misses Hegwig too much and gets mad enough to start writing to her with his replacement stupid owl, Gimi. Hedwig may be a ghost; (the story's in Harry's POV). Read on to see the letters between Harry and Hedwig!

"Percy?" Nico asked, a funny expression crossing his face. "Yup?" I responded easily. "Are you sure attending a wizarding school was a good idea?" "Nope, but I'm going with it," I said with a sly grin.

Harry Potter is used to being the Hero of his world. He and every other wizard believes he is the destined savior of the world. Now that wizard world knows Voldemort is back Harry is going to need protection. Percy Jackson has finally defeated Gaea and saved the world yet again and thinks things will start to calm down. Unfortunately for him, he is that protection. Except he can't do it alone. He is going to need the help of six certain people. Worlds collide in Demigods at Hogwarts. (Guys I suck at summaries. I swear the book is better.)

Percy Jackson: Camp Halfblood's best demigod, boyfriend of the smartest girl in the world, been successful in all his quests. Harry Potter: The most powerful wizard ever since he survived the killing curse, killed Voldemort the most horrible guy in the world and is repeating his seventh year at Hogwarts. Little did these two boys know that these two worlds have been secretly at war since Camp Halfblood apparently stole Pandora's Box which is needed to keep the wizarding world away from war. Disputes are rising. Families are fighting against eachother, taking sides. The Ministry of Magic is going to put a stop to this. They contact the Camp at Long Island and begin to find the perfect selection of demigods and wizards to defeat the power hungry goddess who has stolen the box.....NEMESIS. NOTE: THIS IS NOT MY STORY! FULL CREDIT GOES TO JK ROWLING AND RICK RIORDAN FOR THEIR AMAZING IDEAS. THIS STORY TAKES PLACE AFTER THE HEROES OF OLYMPUS AND AFTER DEFEATING VOLDEMORT. THANK YOU!!

[Set after Percy Jackson and The Olympians: The Last Olympian and in Harry Potter and The Order of Phoenix] The Titan War has ended, but the demigods yet have a peace. Especially the children of the Big Three: Thalia Grace, Nico Di Angelo, and Percy Jackson. Hecate has revealed the identity of the mortal she once upon a time blessed. She stated they didn't know anything about their world, and that they could a powerful ally. And so Percy, Nico, and Thalia found themselves in the world of magic. Their mission is to act as transferred wizard students from America to Hogwarts, and watched if the Wizards deserve to have their alliance. Everything became more difficult when Harry Potter and Golden Trio came into the picture.

Set six months after the House of Hades, and in the Harry's fifth year at Hogwarts. Percy Jackson, Son of Poseidon, Hero of Olympus and more recently, Survivor of Tartarus, has been given a quest. Along with his two cousins Nico Di Angelo and Thalia Grace, he must go undercover at Hogwarts School of Witchcraft and Wizardry for a year. Their objective? Protect Harry Potter, Ron Weasley and Hermione Granger. Harry has had a rough summer, what with the dementor attack and the Dursleys. He thinks life back at Hogwarts will turn things around, only to realize that he is facing a year of ignorance and scorn. When the golden trio meet the children of the Big Three, will they become friends, or worst enemies? *Currently being rewritten under the same author. I'm leaving this one up for anyone that still wants to read it, but you can find a slightly different, hopefully better version on my page*
