“Sup, guys,” Will said. “This is your new brother, Leo—um, what’s your last name?” “Valdez.” Leo looked around at the other campers. Was he really related to all of them? His cousins came from some big families, but he’d always just had his mom—until she died. Kids came up and started shaking hands and introducing themselves.

None of them looked like the others—all different face types, skin tone, hair color, height. You’d never think, Hey, look, it’s the Hephaestus Bunch! But they all had powerful hands, rough with calluses and stained with engine grease. Even little Harley, who couldn’t have been more than eight, looked like he could go six rounds with Chuck Norris without breaking a sweat.”

“He’d perfected his wolf stare over the last few months–a look that said: However bad you think you are, I’m worse. After strangling sea monsters and running over gorgons in a police car, Percy wasn’t scared of gangs. Pretty much nothing in the mortal world scared him anymore.”

“Let us find the dam snack bar,” Zoë said. “We should eat while we can.”
Grover cracked a smile. “The dam snack bar?”
Zoë blinked. “Yes. What is funny?”
“Nothing,” Grover said, trying to keep a straight face. “I could use some dam french fries.” (The Titan’s Curse - chapter 14 page 208)”
