It was an average day a Goode High... until two teenagers and a box appeared.

The box just so happened to land on top of a certain demigod with black hair and sea-green eyes.

"OW!" He yelled, glaring at the box.

The class stared at him. The teenagers did too.

"Um... Perce?" One teen asked, a younger-looking boy with jet-black hair and dark brown eyes asked.

"What are we doing here?" The other teen demanded, a tall girl with black hair and electric-blue eyes.

"Nico? Thalia?" Percy asked, "What are you doing in my history class?"

"Donno," Nico said, then looked at the teacher, "Oh, hey Mr. Blofis."

"Nico. Thalia," Paul said in shock.

Thalia decided to get a closer look at the box, and discovered a note taped on it.

"Hey guys," She said, "Look."

"What does it say?" Percy asked.

Thalia cleared her throat, and began to read aloud.

Dear demigods and mortals,

The Fates have decided that this class needed to known about the mythological world, so they decided (with my help, of course) to freeze time in this classroom. To teach the mortals about our world, they decided to bring five books, all written in Percy's perspective of his quests. The books are: The Lightning Thief, The Sea of Monsters, The Titan's Curse, The Battle of the Labyrinth, and The Last Olympian.

Oh, and don't worry about the mortals telling. After the books are finished they will keep their memories, but be unable to tell anyone. Thalia, Nico, introduced yourselves, tell your parentage and full names only, no titles. Percy, don't reveal your parent, it will be revealed in the book.

From the awesomest god ever,

Apollo (and the Fates)

"Well," Thalia said, looking around, "Hello, everyone. I'm Thalia Grace, daughter of Zeus."

"ZEUS?!" one kid in the back said, "But, wasn't he a myth, you know, to explain storms?"

The others nodded in agreement.

"No," Thalia said, "All those myths- they're real. The gods, the monsters, everything. Me, Nico, and Percy are demigods, Greek heroes. We've fought monsters and have been in a war."

"That's stupid," one kid insisted, "I mean, Percy a HERO? Greek mythology real? That a good one!"

He laughed. Thalia glared daggers at him.

She summoned a lightning bolt, frying the ground in front of the boy's face.

"You better start believing it, kid," She said venomously, "Before I zap your teeth out."

"Whoa, Thalia, calm down," Percy said, stopping her, "We weren't so quick to believe it either, remember- well except for Nico, but he was just plain crazy."

"HEY!" Nico protested.

"Kidding," Percy said, laughing at Nico.

"ANYWAY," Nico said, glaring at Percy, "I'm Nico di Angelo, son of Hades."

"Freaky," A kid in the back muttered.

"And, as you know, I'm Percy Jackson," Percy said, "Son of- well, I can't tell you that yet."

"Yeah, probably because your dad's so lame that we've never heard of before," Matt Slogan said, laughing.

Percy ignored the comment, and simply said: "Trust me. You've heard of him."

"So," Paul said quickly, as to keep a fight from starting, "Who wants to read first?"

"I will," Thalia said grinning, "It's finally time to see what goes on in that head of your's, Perce."

Percy groaned, this was going to be a nightmare!

Thalia picked up the sea-green book, and started to read.

"Chapter 1: I Accidentally Vaporize My Pre-Algebra Teacher..."
