Chapter 1

Annabeth's P.O.V.

Percy and I were sitting on the beach talking. After the Giant War Frank and Hazel left for Camp Jupiter since Frank was praetor and Hazel wanted to be with him. Jason was almost finishing the last of the temples in both Camp Half-Blood and Camp Jupiter . Leo was out with Calypso. Reyna was going between both camps just like Jason. Piper was still at Camp. And Nico was over seeing the renovations on the Hades cabin because apparently the original designer 'thought the children of Hades were vampires." He also has a friend Will Solace he is hanging out with.

We were talking about the summer and if we would have to go on any quests this year when Piper came running up, "Chiron needs you at the Big House!"

"What for?" I asked.

Piper said, "I don't know he just said to get The Seven, Nico, and Lou Ellen.

Lou Ellen is the daughter of Hecate and head counselor for her cabin. I stood up and said, "Come on, Seaweed Brain." Then I took off running without waiting for Percy.

Percy's P.O.V.
When I got to Big House the rest of The Seven including Frank and Hazel, Thalia, Nico, and Lou Ellen were already there.

Chiron cleared his throat," There is a new quest."

"WHAT!" Everyone cried.

"Calm down, Lady Hecate has issued this quest. You see. A long time ago Lady Hecate blessed four mortals. These mortals were Godric Gryffindor, Rowena Ravenclaw, Helga Hufflepuff, and Salazar Slytherin.

"How come I have never heard of them?" Annabeth questioned.

"Oh my gods, Annabeth doesn't know something! It's the end of the world!" Thalia exclaimed. "Ha-ha."

"So, Lady Hecate wants you all to go to a school for magic and protect a boy named Harry Potter and his friends Hermione Granger and Ron Weasley. Harry will be in his 5th year at school. Do you all agree?"

"Sure" everyone but Thalia and Leo replied.

"What about the Hunters I can't just leave them for a whole year!?"

"Lady Artemis has said you may go on this quest."

"...fine "She agreed.

"What about Calypso? I just got her back from Ogygia."

"She can come see you later."

"This better be worth it."

Leo was a lot more serious now that he had Calypso with him at Camp.

"What are we protecting him from?"

"An evil wizard named Voldemort." Suddenly all the guys but Nico were ROFL.

"Moldy shorts." Leo choked out.

"What's the name of the school, Chiron?"

"Uh...Hogwarts." He said somewhat reluctantly.

Nico's P.O.V.

Before I was mad that the guys were laughing at Voldemort because he was causing my dad a ton of paperwork by splitting his soul into seven pieces AND all the killing he and his 'Death Eaters' (Thanatos was NOT amused) were causing, so all in all it was NOT a laughing matter. But when I heard the schools name was Hogwarts I had to start laughing. (I know, I know. It's the day Nico Di'Angelo laughs. ) Eventually (after 10 minutes) Piper had to charmspeak us to stop laughing. "You all leave tomorrow, so I suggest u pack and get some rest. And you mustn't tell ANYONE you are demigods, say you are American Exchange Students from Delphi Academy of Magic.
