More quotes by Rick Riordan, The Son of Neptune

"Two hundred Romans, and no one’s got a pen? Never mind!"He slung his M16 onto his back and pulled out a hand grenade. There were many screaming Romans. Then the hand grenade morphed into a ballpoint pen, and Mars began to write. Frank looked at Percy with wide eyes. He mouthed: Can your sword do grenade form?Percy mouthed back, No. Shut up."
"Um...is that thing tame?"Frank said.The horse whinnied angrily."I don't think so,"Percy guessed. "He just said, 'I will trample you to death, silly Chinese Canadian baby man'."
"Reyna sent me to get Percy,"Frank said. "Did Octavian accept you?""Yeah,"Percy said. "He slaughtered my panda."
"Frank stared at him. "Unfair? You can breathe underwater and blow up glaciers and summon freaking hurricanes-and it's unfair that I can be an elephant?"Percy considered. "Okay. I guess you got a point. But the next time I say you're totally beast-""Just shut up,"Frank said. "Please."Percy cracked a smile."
"Life is only precious because it ends, kid. Take it from a god. You mortals don't know how lucky you are"
