Chapter 1: Time Travel

3rd Person P.O.V.

Today, at Camp Half-Blood, Katie was chasing Travis and Connor Stoll around the camp after they pranked her cabin, Grover, Thalia, Rachel, Nico, and Annabeth were inside the Athena cabin, talking about their results in the search for Annabeth's missing boyfriend, Percy Jackson, and the supposed "Roman Camp," where he was believed to be at, Clarisse and Chris were sparring in the arena, and Jason, Leo, and Piper were working on the Argo II, when a sudden yellow light, engulfed all of them and they fell on the floor with a "thud!"

When they looked up, the 12 Olympians, plus Hades, were sitting on their thrones, staring intently at the 13 children, whom had just appeared in the room.

"Why did you summon us?" Thalia asked.

Zeus responded, "We did not summon you. Who are you?"

"We're demigods, and what year is it?" asked Annabeth.

"It is 2001," responded Athena.

The demigods all groaned and Annabeth responded, "We're from 2011."

As she said this, a box, which had sun designs all over it, with 10 books and a note on top of them, landed on the floor.

Thalia went up to the box, took out the note, and read, "Dear Olympian Council and audience, I have sent these demigods and satyr from the future (2011), to the past, with the objective to read 10 books, involving our beloved here, P-Percy Jackson. Gods, do not harm these demigods or try to change the future in any way. Sincerely, Phoebus Apollo (Awesomest God of the Sun).

At this, Poseidon paled, knowing this was his son.

Annabeth was on the verge of tears, while the Gods and demigods were shocked.

Finally, Athena said, "Well, introduce yourselves if you please."

They each obliged to Athena's wishes.

"Clarisse La Rue, daughter of Ares," Ares looked at her with pride.

"Travis and Connor Stoll, sons of Hermes," they sang, and Chris added, "I am as well." Hermes smiled at them, before giving each of them a thumbs up.

"Katie Gardner, daughter of Demeter," Demeter smiled warmly at her.

"Grover Underwood, Satyr," Zeus glared at him.

"Annabeth Chase, daughter of Athena," Athena smiled worriedly at her daughters depressed state.

"Thalia Grace, daughter of Zeus, and the reason I am no longer a tree will be in the books," Zeus smiled happily, while Hera glared.

"Nico Di Angelo," Hades' eyes widened, "and my parentage will be revealed in the books," Hades let out a breath of relief, but still wondered "How did he get out of the Lotus Hotel and Casino, and where is Bianca?"

"Rachel Elizabeth Dare, Oracle of Delphi," Apollo cheered happily, saying, "Finally the Oracle switched bodies!"

"Leo Valdez, son of Hephaestus," Hephaestus nodded towards Leo with a smile on his face.

"Piper McLean, daughter of Aphrodite," Aphrodite smiled hugely at her daughter and waved.

Then, Jason stepped out, and Zeus nearly had a heart attack, "Jason Grace, son of Jupiter," Hera smiled at him, while the other Gods asked, confused, "Why is there a Roman with the Greeks?"

Thalia answered, "It will be revealed in the books."

After, the introductions were complete Thalia took out the first book and read, "Percy Jackson and the Olympians: The Lightning Thief," at this all the demigods winced, whilst Annabeth's eyes became glossy.

"Well, who would like to read first?" asked Thalia.

"I will daughter," answered Zeus.

He opened the book and read "I Accidentally Vaporize My Pre-Algebra Teacher."

Alright, well this is my first fanfiction, so please review, and let me know if I got anything wrong. I should be updated once, every couple of days (2-4). Also, I will be doing all 10 books (The entire series will take me until the last book is released), and I will be adding characters when appropriate. Well, I hope you enjoyed!
