“[Piper] rushed to get dressed. By the time she got up on deck, the others had already gathered—all hastily dressed except for Coach Hedge, who had pulled the night watch.
Frank’s Vancouver Winter Olympics shirt was inside out. Percy wore pajama pants and a bronze breastplate, which was an interesting fashion statement.

“Piper and Hazel were ready to go, but first Annabeth turned to Percy, who was leaning on the starboard rail, gazing over the bay.
Annabeth took his hand. “What are you going to do while we’re gone?”
“Jump in the harbor,” he said casually, like another kid might say, I’m going to get a snack.”

“Festus just detected a large group of eagles behind us—long-range radar, still not in sight.”
Piper leaned over the console. “Are you sure they’re Roman?”

"What does Blackjack want?" she asked.
"Donuts," Percy said. "Always donuts.”
