Un simple hasard, une simple erreur. Mais cette erreur à changée la vie d'Hermione et a changé le cours des choses. En pleine guerre, Hermione va rater un transplanage et va atterrir... Bon je ne vais pas vous le dire sinon ça va gâcher le suspense MAIS ça a un rapport avec Percy Jackson! Bon du coup je l'ai tué moi même mon suspense (T.T) Mais bon, c'est pas si grave finalement!

Harry's life is mess. He starts off as a nobody, becomes one of the most famous people in the wizarding world, then finds out his dad is the king of all gods and not James Potter, monsters and dark wizards are trying to kill him every chance they get, and he's apart of two great prophesies that both say he can either destroy or save the world. Can his life get any worse?

Harry, Ron and Hermione are invited back to redo their seventh year. At the same time, the Seven, plus Nico and Thalia are sent to Hogwarts on a quest. They soon find out that there is no time to enjoy themselves, though, because something is rising, and it is rising fast... [After Blood of Olympus and the Deathly Hallows. All rights go to J.K. Rowling and Rick Riordan.]

Es un crossover entre Harry Potter y Percy Jackson,en esta historia cuenta un poco de la vida de Harry Potter así ¿Como quien es en verdad? o ¿Quien era antes de que eso pasara?...

Deux sangs mêlés, d'une grande puissance, on était détecté.  Une des jeunes filles est la sœur de Percy.  Ils ne se sont pas vus depuis quatre longues années. Percy, Annabeth et Clarisse sont choisis par Dumbledore, eux, et seulement, eux doivent y aller...  Plonger dans cette nouvelle histoire, une histoire de doute, de tristesse, mais surtout, d'amour, de confiance et d'amitié.

A secret kept from Percy by Chiron and his mother has left him reeling, but when a protection detail is needed for a special boy in England, Percy's newfound talents might be the only thing that can save them all.

Rosa is a demigod who gets accepted into hogwarts. She soon meets Severus, James, Peter, Sirius, Lily, Remus, and Marissa, another demigod. Dumbledore bashing. Severus/OC, James/Lily ((Under editing))

A series of one-shots based off HoO characters in Hogwarts. Be prepared for insanity. - CANCELED AND COMPLETE

HP PJO crossover challenge.

In all the crossovers when demigods go to Hogwarts, have you ever wondered why Chiron sent the accepting ones accepting of the Romans? This is my story when he sends a person who's not so keen on the Romans- Clarisse.

Annabeth has mysteriously disappeared and the demigods are worried. Chiron's centaur friends from England have confirmed that a girl matching Annabeth's description, has attended Hogwarts a few weeks after the semester started. Chiron sends the seven and Nico to check the lead out, BUT they have to attend the school too. What they find out once they get to Hogwarts is SHOCKING

A child of the Rich One rises. Wielding a smile masking a plotting mind. Carving a righteous but dark path through a world more vast and mysterious than ever imagined. In this game of gods and men, it's her time to shine. Fem!Harry. Book 1.

The 7 (and an unhappy Nico) find a mysterious letter. After opening it, they are whisked off into a dark room. The same goes for Harry Potter, Katniss Everdeen, Jade Harley and many others. A letter, then a dark room. After that, they meet up with each other. Absolute fandom hell happens. Fun, isn't it? (ignore mah weird summary) Rated K ,may change the rating.

Harry Potter, on new adventures. This time, in the US! Watch Harry deal with demigods, monsters, weird friends, and one royally fucked up family!

Violette Potter avait imaginé sa vie très différemment pour l'après guerre, certainement pas enceinte en Amérique et avec son filleul et ho les Dieux Grecs existent. Fem Hp. MW/RW/GW bashing. Past FW/VP, Kreatur est génial, tout comme Luna, Neville et George. PS : Percy n'est pas totalement un idiot. Famille nombreuse au passage

State Farm employees use their wonderful teleportation abilities to save fictional characters-as long as they're insured. -SPOILERS. (duh.) -I WILL take requests. (Currently holding characters from Percy Jackson, The Hunger Games, Harry Potter, Game of Thrones, and Avatar: The Last Airbender)

This is a Percy Jackson/Harry Potter crossover! My first fanfic! Please enjoy all the humor!

It had been done before. A bridge to connect two worlds, two worlds kept separate for the safety of everyone. But yet... Ariadne Jackson wasn't a normal girl. That much was clear. But she lived a normal life with a normal family and normal London. That is, until two worlds came crashing into her. Two worlds that fought to stay apart but were destined to come together.
