“Annabeth,” he said hesitantly, “in New Rome, demigods can live their whole lives in peace.”
Her expression turned guarded. “Reyna explained it to me. But, Percy, you belong at Camp Half-Blood. That other life—”
“I know,” Percy said. “But while I was there, I saw so many demigods living without fear: kids going to college, couples getting married and raising families. There’s nothing like that at Camp Half-Blood. I kept thinking about you and me…and maybe someday when this war with the giants is over…”
It was hard to tell in the golden light, but he thought Annabeth was blushing. “Oh,” she said…
“I’m sorry,” he said. “I just…I had to think of that to keep going. To give me hope. Forget I mentioned—”
“No!” she said. “Gods, Percy, that’s so sweet.”

“And,” Annabeth continued, “it reminds me how long we’ve known each other. We were twelve, Percy. Can you believe that?”
“No, he admitted. “So…you knew you liked me from that moment?”
She smirked. “I hated you at first. You annoyed me. Then I tolerated you for a few years. Then—”
“Okay, fine.”
She leaned in and kissed: him a good, proper kiss without anyone watching—no Romans anywhere, no screaming satyr chaperones.
She pulled away. “I missed you, Percy.”
Percy wanted to tell her the same thing, but it seemed too small a comment. While he had been on the Roman side, he’d kept himself alive almost solely by thinking of Annabeth. I missed you didn’t really cover that.”

"Blue elephants."
"Blue elephants."
"Kiss me you fool."
"You fool.”

“Everyone thinks you've been kidnapped," he said. "We've been scouring the ship. When Coach Hedge finds out- oh, gods, you've been here all night?"
"Frank!" Annabeth's ears were as red as strawberries. "We just came down here to talk. We fell asleep. Accidentally. That's it."
"Kissed a couple of times," Percy said.
Annabeth glared at him. "Not helping!”
