CHAPTER 1

"Percy, I have blue cookies!" shouted Thalia.

Percy shot out of bed and raced outside, bumping into Thalia.

"Where are the cookies?" asked Percy, but as a sly grin crept across Thalia's face he realized, "Wait a minute there are none... Pinecone Face, I'm going to kill you!"

"As much as I would like to fight right now, Kelp Head, we've got to get the Big House, Chiron wants to see us."

"This better not be another quest, not after we just finished with the war. I still have nightmares and flashbacks from that place," Percy shuttered, then quickly changed the subject

"Hey Pinecone Face, race you to the big house!"

And with that, they were off.

•••

Once at the Big House, the Seven Demigods and Nico were already sitting.

"Now heroes," Chiron began, "I know you have been through so much but I'm afraid I have a quest for you," he paused, waiting for the demigods' reactions.

"What?! I am not going on another quest after going through that place!" Percy demanded.

Everyone else broke into complaints.

Chiron stamped his hoof on the ground, "Enough! This is a different type of quest, requiring different abilities. You will be attending a foreign school as exchange students. The school is part of Hecate Pet World, where witches and wizards are real."

A series of laughs followed Chiron's absurd comment.

"As in the ones with pointed hats and sticks?" Leo muttered between laughs.

Chiron continued, his face becoming more serious, "As I was saying, you will attend the school as exchange students to protect a boy named Harry Potter from harm. He believes there is no longer a threat because he defeated his mortal enemy, Lord Voldemort."

"Moldy Shorts..." the boys snickered.

"Chiron," Annabeth interrupted, "You never did tell us what this school is called."

"Hogwarts, of course!" Chiron answered.

More laughter.

"Pig Pimples!" laughed Jason.

"When do we leave?" Hazel asked, "And how long will we be gone?"

"You leave tomorrow after receiving a blessing from Hecate to do magic, and will attend Hogwarts for a year," Chiron responded.

Leo suddenly became serious, "Can Callie-"

"And Will," Nico added.

"Can Callie and Will come with us?" finished Leo.

"I'm afraid not, Hecate specifically said only you nine," Chiron said sadly.

"How are we going to get to Pig- Hogwarts?" Frank asked.

"By flight," Chiron said.

"I am not getting on an airplane. DO YOU WANT ME TO DIE?!" Hazel said and Percy, Nico, and Thalia agreed with her.

"Lord Zeus agreed not to blast you out of his domain. Plus he would not blast a plane with two of his children on it. Now off to bed, you have to be ready to go by 10:00 a.m. tomorrow," Chiron stated as everybody walked out.

•••

"Ron, wake up! There's food downstairs and everyone is waiting for you," Harry said as he shook Ron awake.

"I'm coming, I'm coming," Ron said lazily as he got out of bed and walked to the door.

They got downstairs and started eating when an owl flew in through the window.

"Ginny, looks like your letter has arrived," stated Mrs. Weasley.

"What are those other letters? Wait, it looks like we're going back to Hogwarts!"

Hermione said excitedly. They opened their letters. "I wonder who these exchange students are," she said curiously.

"Oh, I forgot to tell you we will be hosting nine exchange students and helping them get to school," Mrs. Weasley said.

"When will they get here?" Asked Ginny.

"Any minute now."

As if on cue, there was a knock at the door.

"There they are," Mrs. Weasley said and went to get the door.

As soon as the demigods walked inside, Hermione ran up to them, "Percy, Annabeth, Nico, Thalia!" She exclaimed.

Annabeth ran forward and hugged her, "Hermione I thought you were dead you just disappeared,"

"So this is the Hermione I've heard about," Piper said. "Daughter of Athena right? I'm a daughter of Aphrodite," Piper finished in Greek. The mortals gave them weird looks.

"Guys," Hermione said to the wizards, "these are my friends from a camp. This is Percy, Annabeth, Thalia, Nico, Piper, Hazel, Frank, Jason, and Leo," Hermione pointed to them.

She looked at the demigods "Guys, this is Ron, Harry, and Ginny."

"Nice to meet you," Ginny said.

"The girls can sleep with either Hermione or Ginny and the boys can sleep in Bill and Charlie's old rooms," said Mrs. Weasley.

"Umm… Mrs. Weasley, thank you so much, but Percy and I get nightmares and it is best if we… sleep in the same room," Annabeth said embarrassedly.

"That's fine, you two can sleep in Percy's room," Mrs. Weasley said.

"Thank you," Percy said as they walked up to their room.

•••

The next few days at the burrow were uneventful. The demigods and wizards spent some time getting to know each other, and Annabeth and Hermione were catching up with each other.

"Annie I know about the war now that you told me, but can you explain why you and Percy have nightmares?" Hermione asked Annabeth.

"Percy and I fell into Tartarus," she whispered.

"I had no idea! How did you make it out alive?"

Annabeth explained all about Tartarus, shivering at parts.

"Nico also went through except he was alone and in there for so much longer. When he got out he was put in the jar," then she added, "Will helps him with nightmares.

"Wait, Will and Nico are dating?" Asked Hermione to change the subject.

"Yeah they got together when the war ended," Annabeth said great fuel for the change of subject.

"I'm so happy for them. It's nice Nico has someone after all he's been through," Hermione exclaimed.

"Girls, time to go to Diagon Alley," Mrs. Weasley interrupted.

The daughters of Athena ran downstairs.

"Now that we're all here we will be taking floo powder to get to Diagon Alley who wants to go first?" Questioned Mrs. Weasley.

Chiron had explained to them what floo powder was, so Leo quickly said, "I'll go!"

Leo stepped into the fireplace and said "Diagon Alley," and was off.

•••

Once everyone had gotten to Diagon Alley, thankfully with no one ending up in the wrong spot they decided to go get their money and then split into groups to get there school supplies

"Mrs. Weasley where do we get our money?" Asked Frank.

"Gringotts Bank of course," she exclaimed.

They walked over to Gringotts and went up to a Goblin. "Can we get some money out of our vault?" Annabeth said.

The Goblin spotted Nico and Hazel and said, "My lord, My Lady," as he bowed to them.

"Your father has a vault set up. It is for all of you. My lords, please follow me," the Goblin spoke.

Nico and Hazel looked at each other and followed the Goblin

"Your vault number is 666. Your father made sure to set up the vault not too deep down because of your flashbacks," the Goblin said to them.

Nico and Hazel nodded as they got in the cart to go to their vault. Before they got in they told the others, "Just wait here we'll be right back."

•••

They got down into the vault and got out of the cart, Hazel looking sick said, "We better not have to do that again."

They walked to a vault and the Goblin opened it, "Go in and grab what you need," The goblin said.

The children of the underworld walked into the vault and looked around. It was magnificent, the walls were black but had skeleton patterns on them, there was a throne obviously dedicated to Hades, and there were piles of Dramechs, Galleons, Nuts, Stickles, And on the wall there were weapons. The children ran up to the piles of money and scooped up so much they needed to grab a giant bag to carry it.

"I think this is enough," Nico stated. Hazel agreed so they left.

They got back in the cart and speed upwards. Hazel looked really green and was about to vomit when they go to the top. Frank saw Hazel looking sick and slowly helped her out of the cart.

Nico looked at how caring Frank was and automatically missed Will. Then he said, " I miss Will."

Surprisingly Leo said, "I know man I miss Callie," he said sadly, "It's unfair that Hecate won't let them come."

Nico nodded his head in agreement. "I need Will to help with the nightmares, I mean it would be really bad if at Hogwarts I woke up everyone to my screaming," Nico said nervously not realizing that Harry and Ron were listening.

To change the subject Percy said, "To get all of our school supplies why don't we split up. Annabeth and I will go get books. Piper and Jason will go get cauldrons. Hazel and Frank will get Quills and Ink and Thalia, Nico, and Leo will get us candy just to have. We will meet at the robe shop to get our robes and then we can all go get pets and wands," Percy explained, happy with his good idea.

•••

Jason and Piper to ask a lot of wizards to finally find the cauldron store. When they got there they said,

"So for every one of us, we need nine cauldrons. Right?" Jason asked. "Yep," Piper said popping the P. They walked up to the front of the store and got the cauldrons then walked over to the robe shop.

Meanwhile, Hazel and Frank went over to the quill shop and picked out different quills for everyone for Hazel and goldish quill, for Frank a eagle feather, for Percy a white feather that they dyed blue, for Annabeth a grey owl feather, for Jason an eagle feather that kind of looked like a bolt of lightning, for Piper a dove feather, for Leo a Vulcan feather, for Thalia a quill-like Jason's, and for Nico a raven feather.

Meanwhile, Percy and Annabeth walked to get the books.

"Wise Girl, what does this say?" Percy asked.

"It says Fantastic Beasts and Where to Find Them, Seaweed Brain," Annabeth responded.

"Hey, don't blame the dylistic," Percy playfully said.

"I also have dylistic but at least I try to read," she said.

Meanwhile, Leo, Thalia, and Nico walked over to Honeydukes and were loading up on candy, when they finally finished, they headed to the robe shop.

•••

Once everyone arrived at the robe shop and got fitted for robe's (which they hated) they went over to get wands. They arrived at Ollivanders and walked inside.

"Ah, I've been expecting you, young demigods," Ollivander spoke.

"Ho do you know what we are?" Annabeth asked nervously.

"I'm one myself. Son of Hephaestus," he said.

Leo then said, "Hi bro, I also have the coolest dad.

"No my dad's the best!" Percy yelled

"Guys, obviously my dad's the coolest," Jason said.

"My dad is the best and that's final," Nico said.

Within minutes the demigods were having a full on fight about who's dad is the best, when Ollivander coughed getting the demigods attention.

"Do you want wands?" he questioned.

"Sorry," Piper apologized.

"Oh, it's fine now for the wands. Mr. Zhang," Frank stepped forward, "Holly Wood, Imperial gold core, 14 inches."

It went on, everyone receiving their wands.

Thalia - Pinetree, Eagle feather, 12 inches

Nico - Dead tree, Thestral hair, 13 inches

Percy - Corral, mermaid hair, 15 inches

Jason - Oaktree, lightning bolt, 12 inches

Piper - Apple tree, dove feather, 10 inches

Annabeth - Olive tree, owl feather, 16 inches

Leo - Burnt tree, Phoenix feather, 15 inches

Hazel - Dead tree, gold, 13 inches

The demigods walked out of the shop still fighting over who had the best dad when they bumped (literally) into the golden trio. As this was a normal occurrence for Hermione she just said, "Hey guys."

"Hey, Mione,"

The wizards and demigods took some time to catch up when out of nowhere a hydra jumped out. Harry pushed the demigods out of the way right when they were getting their weapons ready.

"Stay back I got this," Harry said as he fired a spell at the hydra. Harry was shocked when the spell bounced right off.

"Move out of the way we got this," Jason said annoyed.

The demigods including Hermione grabbed their weapons and within a few minutes, the hydra was slain.

"How did you do that?" questioned Harry

"At our school, we train using magic and hand to hand combat," Annabeth responded.

"How did you learn that Mione?" questioned Ron.

"At that camp, I was talking about," she shrugged.

Ron walked up to Hermione and kissed her. Hermione was used to this by now but she didn't like it, she was together with Ron only to keep her cover when in reality she was together with the one and only Draco Malfoy, son of Hades.
