*Long summary: A night out trick-or-treating for Annabeth, Percy, the Stoll brothers, Grover, Nico, Thalia, and Rachel turns deadly when Connor and Travis anger an adult demigod with a prank gone too far. Then afterwards a Halloween party at Camp Half-Blood, and a contest to find out who the mysterious couple is that no one can recognize . . . . Set for the Halloween following the Titan war, so before The Heroes of Olympus. Percabeth/slight Jasper in first and last chapters/slight Tratie.

"Hey, what's this?" Leo asked, holding up a photo.

Annabeth sighed. Only three more months to go before the Argo II was finished and they could travel to Camp Jupiter, were Percy will - hopefully - be, but seeing a picture of her and Percy dressed up for Halloween still tore at her heart.

Her, Leo, Piper, and Jason were going through some old pictures of Chiron's. Jason was holding Piper's hand, and Annabeth was glad to see the two were together. If anyone deserved happiness, Piper did, even if Annabeth didn't completely trust Jason. Not yet, anyway.

Annabeth took the photo. "That would be Percy and me on Halloween."

"What?" Leo choked. "That looks nothing like you!"

Annabeth just smiled. She couldn't bring herself to laugh. It was hard to, knowing her quest to Percy would be in three months. It was putting a terrible and unwanted pressure on her chest. It still seemed like just yesterday that Percy had kissed her goodnight and ran back to his cabin. She couldn't remember a time after Hera had whisked him away that she'd been as happy as she was that night. Now it felt like a distant memory, one already fading away and leaving her to face brutal reality . . . Percy was with the Romans, and she didn't know if he even remembered her or not.

"I know," she said. "Aphrodite really did a good job, didn't she?"

Piper raised an eyebrow. "Mom dressed you up?"

"And Percy," said Annabeth. "No one recognized us, and the only ones who knew who we were were Connor and Travis, Thalia, Nico, Grover, and Rachel."

"Wait, what do you mean?" Leo asked.

"It's a long story." Annabeth looked down at the photo.

"Oh, do tell," Piper said in a sing-song voice. "I love a good story."

"Yes, do tell," a voice said. Annabeth turned. Chiron was standing in the doorway, leaning on a walking stick. "This I must hear."

Annabeth blushed. "Well, it started the night before Halloween . . ." she started.
