Cathy just stared.

"Sorry, I didn't introduce myself. I'm Annabeth." The girl said. Then after a pause, she slapped the guy, who then introduced himself as Percy.

"Hi, I'm Cathy." She said.

"Hi Cathy! This is Camp Half-blood. I know this might be hard to take in, but all of us here, and you are, well, half god." Annabeth said.

Cathy gasped.

"WHAT!" Cathy screamed.

"Yes" Annabeth said. "It may take a few days, but one of your parents is a god, and they will claim you. Do you have a parent who was never there?"

"Yeah, my mum." Cathy said.

"Well, your mum is a Greek goddess, and in a few days, she should claim you. How old are you?" Annabeth asked, staring at her intently.

"12. My birthday is tomorrow, actually. At least I think." Cathy said, it all coming out in a rush. She realised the reality of what was happening to her.

"Well, today is the 23rd of January, is that the date?"

Cathy gasped. "Yes, it is! Today's my birthday!"

Annabeth's eyes were wide open.

"That means that you will get claimed today. It's a law that all demigods, thats the official name, or half-bloods, have to be claimed by 13."

"CHIRON! GET OVER HERE. WE HAVE A NEWBIE ABOUT TO TURN THIRTEEN!" Annabeth yelled.

Then Cathy nearly fell over. A horse with a man's torso and head replacing the neck came walking (Trotting?) around the corner, with a kid with a goats legs walking next to him.

"Wh-what is THAT!" she managed to croak out, as Annabeth caught her.

"He is a centaur, half man, half horse, and the boy next to him is a satyr, a half man, half-"

"Goat." Cathy cut in.

"Yes."

"And when you say Chiron, do you mean, like, Chiron Chiron?"

"Yeah, Chiron from the myths" said Percy, jumping into the conversation.

"Well, what's her name Annabeth?"

"Cathy,wait, what's your last name?"

"Hallows." Cathy replied.

Then everyone gasped.

"What!" Cathy asked

Annabeth pointed above her head.

There was a black holographic circle with two twin torches burning inside of it.

Then to her complete and utter amazement, everyone bowed down as Chiron shouted

"All hail Cathy Hallows, daughter of Hecate."
