Title: Headmaster Snape and The Percy Jackson Books

Rating: T

Summary: Harry, Hermione, the Weasley's, the Malfoy's, and the Order land in a room that was once used by the Founders. They were summoned by Headmaster Snape and told, in-order to leave, they must read the five books that detail Percy Jackson's adventures. Why does Snape want them to read these books about some kid? In the end, they will all find out. Crossover of Percy Jackson.

Disclaimer: I don't own any of Rowling or Riordan's characters and I'm making nothing from this.

Chapter 1: The Summons

The room that Headmaster Snape chose was one of many rooms that the Castle told him about upon becoming Headmaster. The room was covered in runes and magical writing from Greece, Rome, Egypt, and the Nordic countries. It was truly a magical place. He could feel the hum of the castle as he walked around this room. Yes, this would be perfect for what he intended to do.

What needed to be done!

He chanted the words and the room was filled with a brilliant light. A few moments later a dozen, or more, bodies landed on the floor. The room took away their wands and locked away their magic. There would be no violence in this room.

"Bloody hell, I was having a nice dream," the voice of Ron Weasley said.

"Ron, is that you?" Harry Potter's voice said.

"Yeah, mate."

Soon other voices were asking if anyone else was okay and then they all saw him. The Order went for their wands and Narcissa and Lucius got between them and him. That's when they noticed they didn't have their wands.

"We don't have-."

"Then I'll kill him with my own hands," Harry said.

However he couldn't move. The Founders has thought of everything.

"What is this room?" Remus asked.

"This was one of the many original rooms that the Founders created," Severus told him. "Even I'm not sure of its full function. However, it does have the ability to bring people that it feels will help the castle out. And only the rightful Headmaster can use it."

"Which was Dumbledore."

"Harry, if Snape is telling the truth then he's the rightful Headmaster."

"He's not, McGonagall is."

"But I doubt she could have found this room."

"That would be correct," McGonagall said, "This room is hidden from me."

"Then why are we here?" Draco asked.

"To read some books," Severus answered.

That wasn't the answer that Draco was looking for.

"Read bloody books," Ron said, "Okay, Hermione, have fun."

"To leave this room you must read the books that detail a boy name Percy Jackson. Trust me when I say that you won't be able to ever leave if you don't. Food and drink will be provided as well as sleeping arguments."

"We have a business."

"I have a job."

"Time will stop for everyone inside this room. Don't worry, you won't lose anything by reading them."

"I bet he's a Death Eater," Harry remarked.

"Oh I think you'll like him," Severus said.

"Yeah, he's a Death Eater."

"Is he a real person?" Hermione asked him.

"Yes, he is," Severus answered.

Severus waved his hand and the first book appeared. He walked over and handed it to Mrs. Weasley.

"Ladies first," he said and he saw her glaring at him.

"We're only doing this to get out of the room," she told him and then looked down at the book. "Percy Jackson and the Olympians; the Lightning Thief."

"How can you steal lightning?" Harry asked.

"Don't look at me, dear, it's just the title of the book."

"The Olympians are Greek and Roman," Hermione said. "Strange."

She opened the book and read, "I accidentally vaporize my pre-algebra teacher."

"Strange book, strange title," Remus said.

"Now let's begin," Severus said and Mrs. Weasley began.

A/N: Sorry about ending the chapter there. The next one will cover the first chapter of the first book. I'm also doing this using the Kindle edition of the first book and will post about twice a week. Promise. Also would like to note that after two chapters from the book there will be a small chapter where Harry and the others talk about things and, of course, they will all be wondering what Snape is up to.
