Prologue

A year after The Last Olympian…

Chiron had called a meeting in the pavilion. Everyone was there, they had to be. Something important was going on.

Seventeen-year-old Percy sat at the Poseidon table next to the fifteen-year-old boy they had discovered back in March. Percy liked the boy, he was hilarious and fun to be around. He was quiet now, though.

The boy's name was Jakob, and everyone called him Jake. He was another son of Poseidon, something else Poseidon forgot to mention. His mother died back in February. Poseidon had no choice but to lead him to the camp. The boy was a spitting image of Percy, with the sea green eyes and black hair.

"What's going on, Perc?" asked Jake in a small voice. Jake was the only one who called Percy, Perc.

"I don't know." said Percy honestly.

Chiron stood up on all fours (yes, he was a centaur--half-human, half-horse. Please, no gasps. If you are reading this, you should have read the first five books.) and spoke, "Welcome, everyone. I have a very important announcement to make. We have a new half-blood coming to the camp."

"No surprise, there." said Clarisse.

Everyone agreed. Since the end of the war, more and more half-bloods have been popping up all around the United States. Fourteen new ones had come to the camp, including Jakob.

Percy glanced at Annabeth, his girlfriend. She gave him a pained smile.

Chiron continued, "It is a girl. Her name is Alena. She is… well, I understand this may seem a little weird, but her father is Zeus and her mother is… Artemis."

Silence for a minute.

Adam, a new kid, said, "Woah. Isn't Artemis, like, Zeus's daughter? What are they doing in bed?"

Jake spoke up. "That doesn't really matter that much. It may be a little creepy to you and I, but the real problem is that she is ARTEMIS'S daughter. Artemis is a virgin goddess, remember? Never supposed to have sex or get married?"

"It's still sick." said another new girl, Bridget. She flipped her blond hair over her shoulder.

Jake sighed. "No way of getting through to these people." he whispered to Percy. Percy smiled.

"Yes," said Chiron, "You are correct, Jake. She is a virgin goddess, and ultimately did something she never should of done. But the past cannot be rewritten.

"The real problem is that Alena has extraordinary powers because she is a daughter of the king god and a virgin goddess. She can do anything, such as control the elements, like Zeus, Poseidon, and Hades. She can also create a enchilada out of thin air. I think Grover may like that skill."

Grover, a satyr, grinned from over in his seat. "I like her already."

He loves enchiladas, if you didn't catch on yet.

"She is the key to another prophecy, we just don't know what that prophecy is yet." said Chiron.

"Huh…???" said a lot of people in the crowd.

"Rachel says she is part of a prophecy about a prophecy. Yes, yes, it is all very confusing. Anyway, the girl is coming. She is fourteen and does not have control of her powers yet. I would recommend NOT angering her. Oh, and Artemis and the Hunters are coming along with her."

Groans from everyone.

"Quiet! They will only be here for a few weeks while Alena gets settled. No one worry. Plus all the gods will be coming here tomorrow." said Chiron.

Gasps. All the gods? Hades doesn't even leave the underworld ever unless it is during the winter solstice.

"Yes, all the gods. Before they come, we will all go to Mount Olympus. An assembly will be held there."

Silence.

"Yeah, demigods. This girl is that important."
