This story takes after Heroes of Olympius and Deathly Hallows. The demigods: The seven, Nico di Angelo, Will Solace, Reyna Avila Ramirez-Arellano Thalia Grace, Calypso and Rachel Elizabeth Dare were sent to Hogwarts to study and make allies. But when they arrived, they were mistaken as Death Eaters by Harry Potter, Hermione Granger, Ronald Weasley and Ginny Weasley. What will happen in that school? Will they have a normal year as they wish or will they get into trouble again? I do not own any characters but J.K.Rowling and Rick Riordan does.

Have the demigods after two wars earned some peace? Apparently not. When chiron announces a new quest the demigods will have to face the hardest one ever........school. But this school is different. Hogwarts is fixed and the golden trio is returning hoping for a normal year for once but with the arrival of some new students it doesn't seem like they're going to get one. Will they be friends or enemies?

After the war with Gaia, the seven, Reyna, Calypso, Nico and Thalia are sent on a quest to Great Britain, to go to Hogwarts, a School of Witchcraft and Wizardary in Britain to learn the ways of the forgotten wizarding world. On their quest, they will make friends and enemies amongst the students at Hogwarts. However, one question remains above all others. Will they be able to make an alliance between the two worlds, or will a raging war erupt between them? DISCLAIMER: I DO NOT OWN ANY OF THE CHARACTERS IN THIS STORY, I ONLY OWN THE PLOT! THE PJO/HOO CHARACTERS BELONG TO RICK RIORDAN AND THE HP CHARACTERS BELONG TO J.K. ROWLING! ALL RIGHTS GO TO THEM!

The eight demigods (Percy, Annabeth, Frank, Hazel, Jason, Piper, Leo, and Nico) embark on a quest to the wizarding world as they are assigned to go to Hogwarts, undercover. There they meet the trio as well as many of the other wizards and witches. What will happen when these two worlds meet?

Percy Jackson, Annabth Chase, Nico Di Angelo and Thalia Grace go to Hogwarts. The usual quest to protect Harry Potter and the golden trio. My version though. Set after BoO and during Order of the Phoenix. Percabeth, maybe Solangelo. Ron and Hermione. Harry and Ginny. No Cho I think. Yey my first story on whatpadd and hope you like it.

La guerre contre Gaia est enfin finie. Percy et ses amis pensent enfin avoir la paix. Sauf que Chiron n'en a pas fini avec eux : ils vont devoir aller à Poudlard en mission secrète pour apprendre le plus de choses possibles sur le monde des sorciers et sorcières. Mais qui en a décidé ainsi ? Je tiens à préciser que tous les personnages sont à J.K Rowling et Rick Riordan. Seulement l'histoire m'appartient.

It's after the giant war and Leo has returned with Calypso. It has been a year, Percy and Annabeth are 19 and about to leave for college in New Rome when Hecate arrives with a quest. Percy and Annabeth must go to teach at a famous wizard school and make allies. This school: Hogwarts. Harry Potter is returning to Hogwarts two months after the war. Professor Slughorn has resigned in favour of Professor Snape who faked his death to motivate Harry. There will be two new teachers. One for ancient runes and one for DADA. Harry believes that there's nothing for him to learn from a DADA teacher. That will change quickly when he meets the Heroes of Olympus. See what happens next...soon. Rocking85- Lol!!!
