Annabeth's voice caught on the word friend. Percy was a lot more than that. Even boyfriend really didn't cover it. They'd been through so much together, at this point Percy was part of her--a sometimes annoying part, sure, but definitely a part she could not live without.

I looked at the campers, all of them grim and determined. I tried not to feel like this was the last time I'd ever see them all together. 'You're the greatest heroes of this millennium,' I told them. 'It doesn't matter how many monsters come at you. Fight bravely, and we will win.' I raised Riptide and shouted, 'FOR OLYMPUS!' They shouted in response, and our forty voices echoed off the buildings of Midtown.

Whoa," Connor Stoll said. "Back up. Zoom in right there." "What?" Annabeth said nervously. "You see invaders?" "No, right there—Dylan's Candy Bar." Connor grinned at his brother. "Dude, it's open. And everyone is asleep. Are you thinking what I'm thinking?" "Connor!" Katie Gardner scolded. She sounded like her mother, Demeter. "This is serious. You are not going to loot a candy store in the middle of a war!" "Sorry," Connor muttered, but he didn't sound very ashamed.

True success requires sacrifice.
