Everything was fine until Annabeth got the phone call.

She didn't even know why she had it on her as they sailed down the Greek coast, but in the middle of lunch on the deck her cellphone rang sharply from her pocket.

Percy froze with a hamburger stuffed in his face. Everyone turned to look.

"Um...do we get coverage out here?" Leo ventured.

"No." Annabeth said carefully.

"Who's calling you out in the middle of nowhere?" Piper asked.

Annabeth took the cell out and saw clearly on the lit-up screen

SADIE KANE

She flipped it open it and said

"Sadie?"

"Annabeth, thank god! I swear it wasn't my fault but he saw me and-"

"Hey, hey, calm down. What's wrong?"

"Carter and I are being followed! We need a place to hide."

"Okay but Sadie we're in the middle of the..."

"We'll be right there!"

"What? Sadie...!"

There was a flash of blue and two young teens crumpled to the deck floor. One was a boy with a mop of dark hair and dusky skin. The other was a girl with red highlights who ran up and hugged Annabeth tightly.

"Carter?" Percy said, mystified.

"Hey, Percy." Carter groaned.

"Uh, not that I mind cute girls on my ship..." Leo began uneasily. "But who are these guys?"

"Friends of ours." Annabeth told him.

"You okay?" Frank asked, helping Carter up.

"Yeah..."

As he got oriented again, Percy and Annabeth explained what they knew about the siblings and how they had met, Sadie filling in the details.

Jason whistled.

"So this House of Life thing is right across the river from Olympus?"

"Practically neighbors." Annabeth confirmed.

"Yes, and one of it's lovely members" Sadie piped up, voice dripping with sarcasm "saw me cast a fixing spell and decided to chase me halfway to Forty Second street. And...and..."

She trailed off, gaping.

"Are we in the middle of the bloody ocean?"

Annabeth sighed.

"That's what I was trying to tell you. We're in the middle of a quest."

Carter groaned again.

"Great job, sis." he spat.

"Well, I'm sorry, Annabeth was the only person close by I could think of, how was I to know she wasn't bloody home?"

"You could have asked!"

"In case you missed it, we were being ambushed."

Carter sighed heavily, practically tearing his hair out. He took a deep breath and managed a weak smile at Percy.

"Well, we did need a place to lay low. We aren't exactly well loved in our order. We got spotted by a Magician who was not so friendly to godlings."

Hazel shook her head. "Magicians? Like...children of Hecate?"

"Hecate?" Sadie repeated blankly.

Annabeth spread her hands. "Lets leave explanations for after dinner. Right now, Sadie, Carter...if you need a place to stay...you're welcome to stay with us for a while, so long as you don't mind fighting a few monsters.

Carter grinned, held out his hand, and a sharp, curved blade materialized in his hands.

"I think we can handle that."

A/N: My love for crossovers has reached absurd levels but after the Carter/Percy and Sadie/Annabeth short stories, I had to. I don't know about the timeline being strictly correct but I just liked the idea of the Kanes on the Argo. Anyway, I don't intend for this to be a huge project but I do think it will be a couple of chapters. I hope you like it and thank you for reading/reviewing/ect!
