Percy's POV

"Seaweed Brain, Wake up!" Annabeth called shaking me awake.

"What's up, Wise Girl?" I asked.

"We are going down to Diagon Alley right after we have a quick breakfast downstairs," Annabeth answered.

"How are we going to do our sacrifices?" I asked.

"Oh, Tom's a son of Hermes, so he has a room where he does his sacrifices, we can make our's there too," she replied.

"Oh, okay, I'll change now," I said.

I quickly slipped on a blue shirt and black shorts. I walked down with Annabeth after I put on my sneakers.

After a quick omelette, we walked down to a brick wall. "Um, Lupin, I thought we were supposed to be going to Diagon Alley?" I said confused.

"We are," Lupin smirked.

He raised his wand to the bricks and tapped them in a certain order. The bricks parted and a bunch of shops were revealed. We were at Diagon Alley. "First stop, Gringotts bank, your parents left plenty of money for everyone. It's all in one vault, in fact I think there may be an infinite amount until you no longer need to be in the Wizarding World," Lupin said.

We walked to the end of the Alley. On the front of a tall white building had words engraved on the front door.

Enter, stranger, but take heed

Of what awaits the sin of greed

For those who take, but do not earn

Must pay most dearly in their turn

So if you seek beneath our floors

A treasure that was never yours

Thief, you have been warned, beware

Of finding more than treasure there.

We walked up to a goblin at a booth. His name was Nagnok. We went onto a cart and it was even better than the any rollercoaster, except for the part where Thalia threw up. "Vault 299. Key please," Nagnok said.

Lupin handed him a tiny key. The goblin unlocked it and the door swung open. Piles of knuts, sickles, and galleons. We put some coins in coin bags and distributed them. Soon we were back to Diagon Alley. We split up into groups. Annabeth and Grover went with me, Thalia, Nico, and the Twins went together and etc. We soon departed, and my group went to Ollivander's. "Ah, more demigods. Chiron must have an important mission at Hogwarts. Ollivander, son of Hecate, and grandchild of Hephaestus," an old man said coming out from the back. "Percy Jackson, son of Poseidon, you will start."

The man looked at me and walked into the back. "Try this one. 11" willow, mermaid tail core with Pegasus feathers."

I took the wand and waved it. "Good. Annabeth, daughter of Athena, you're next," Ollivander said. " 10 inches holly, owl feather core."

Annabeth took the wand and waved it.

"and lastly, Grover Underwood, Lord of the Wild. Eleven inches oak, elk horn core."

Grover waved it, Ollivander looked satisfied. We bought out wands and went to get our books and school stuff. We finally went to the Owl Emporium, and it was a nightmare. The owls kept pecking me and bowing to Annabeth. Annabeth and I agreed to share an owl. "Hermione, are all owls nocturnal?" a boy asked.

"No, the Northern Hawk Owl is not," the girl named Hermione answered.

Chiron had mentioned that a girl named Hermione Granger was Athena's child. Perhaps this was the Hermione he was talking about, but she didn't look anything like one. She had brown bushy hair, brown eyes, and pale skin.

"Hermione!" Annabeth yelled hugging the girl.

"Hey, Annabeth, longtime no see,"Hermione greeted.

"You look different," Annabeth noted.

"It's part of Chiron's disguise for me. He had me practice changing my voice so it sounded, er, more bratty," Hermione said.

Hermione flicked her wand, and she become more muscular, athletic, and tanner. Her hair turned into long blonde curls and her eyes turned into a gray color like Annabeth's. They almost looked like twins, except Annabeth was taller and had different clothes on. Hermione's voice became less bratty, and she had more of an American accent. "Ron, Harry, come over here," Hermione said.

"What is it-woah. Hermione?" the boy from earlier asked shocked.

"Ron, Harry, this is Annabeth Chase, my half-sister," Hermione said. "Annabeth, this is Ron Weasely, and that's Harry Potter."

"Wait, Harry Potter as in James's son?" I asked.

"Yeah. What's your name?" the boy named Harry asked.

"I'm Percy Jackson," I replied. "Your father and my father knew each other quite well, I'll explain later when we are at Hogwarts."

"Hey, Hermione, where's Luna and Draco?" Annabeth asked.

"I think Draco's at Madam Malkin's getting new robes with his 'mother', and Luna is at Flourish and Blotts getting new books," Hermione said.

"Wow, sis, I never knew you were blind too," a boy said.

Annabeth's POV

I turned and saw a boy standing there. "Draco? Wow, you guys look really different," I said.

"Oh, sorry, Annabeth," Draco said and flicked his wand.

He was very muscular and tan. He now had short blonde hair and gray eyes like Malcom. He was my favorite brother, and Hermione is my favorite sister next to Luna. "Draco, it's been a while. How's it going?" I asked hugging him.

"It's good. It's been hard to stay undercover. I have to be mean to Hermione and other people including Luna as well," he replied.

"But, now you don't have to pretend to be someone else. We'll explain everything at Hogwarts," I said.

"I have to go back to my 'mother' before she comes looking for me. See you on the train," Draco said.

"See you," I said, and Percy and I rejoined the others.
