"He was making a brave attempt, but Jason could see the sadness lingering in his eyes. Something had happened to him... something to do with Calypso."

"Hmph. Yes. Him. He had the nerve to turn down our offer of immortality and tell us to pay better attention to our children. Er, no offense. "Oh, how could I take offense? Please, go on ignoring me."

"Percy: You just hit the lord of the titans with a blue plastic hairbrush."

"Nico didn't like to be touched, but somehow this brief contact with his father felt reassuring " the same way the Chapel of Bones was reassuring. Like death, his father's presence was cold and often callous, but it was real " brutally honest, inescapably dependable."

"Fortunately, we did most of our athletic stuff inside, so we didn't have to jog through Tribeca looking like a bunch of boot-camp hippie children."

"You're sure?' I asked. 'I mean, the Lord of the Sword is great. But you could also be, I don't know, the Slammer of the Hammer'."

"Jeez, Hazel," Percy said, "tell your horse to watch his language."Hazel tried not to laugh. "What did he say?""With the cussing removed? He said he can get us to the top."Frank looked incredulous. "I thought the horse couldn't fly!"This time Arion whinnied so angrily, even Hazel could guess he was cursing."Dude," Percy told the horse, "I've gotten suspended for saying less than that..."

"Good fighting with you, Seaweed Brain."Ditto."

"The cave floor rumbled. A large stone emerged from the dirt-a smooth, oval rock exactly the same size and weight as a baby god... She wrapped the stone in swaddling clothes and gave the real baby Zeus to the nymphs to take care of... She marched right up to King Cannibal and shouted, "This is the best baby yet! A fine little boy named, uh, Rocky!"

"The Friday before winter break, my mom packed me an overnight bag and a few deadly weapons and took me to a new boarding school."

"Wow," Thalia muttered. "Apollo is hot." "He's the sun god," I said."That's not what I meant."

"Where his eyes should've been, there was only fire, empty sockets glowing with miniature nuclear explosions."

"Nico was devastatingly alone. He'd lost his big sister Bianca. He'd pushed away all other demigods who'd tried to get close to him. His experiences at Camp Half-Blood, in the Labyrinth and in Tartarus had left him scarred, afraid to trust anyone."

"I love Norse mythology - Thor and Odin and Loki - amazing characters."

"That's us, he said. "Those five nuts right there.Which one is me? I asked.The little deformed one, Zoe suggested.Oh, shut up."

"They were startling gray, like storm clouds; pretty, but intimidating, too, as if she were analyzing the best way to take me down in a fight."

"I am the son of Hades. I go where I wish. The darkness is my birthright."

"Travis: The Aphrodite kids were ripping each other's clothes and throwing lipstick and jewellery. It was like a rabid herd of wild Bratz."

"Did you bring me a rat?""He has no time for rats, George.""No time for rats? That's just sad."

"I had a crush on Percy," Nico spat. "That's the truth. That's the big secret."

"If the statue engulfs people in fire, we should send Leo.' 'I love you too, man.' 'You know what I mean. You're immune. Or, heck, give me some of those nice water grenades and I'll go. Ares and I have tangled before."

"With great power comes a great need to take a nap."

"Sometimes wisdom came from strange places, even from giant teenaged goldfish."

"Michael Varus drew his sword. ''My father is Janus, the god of two faces. I am used to seeing through masks and deceptions."

"A general never shows despair. He instills confidence in his troops. He leads them forward, even into the mouth of death."

"I try very hard to be annoying! Don't insult my ability to annoy!"

"Percy hefted a bronze grenade. 'I hope you labelled these right.' He yelled, 'Die, Romans!' and lobbed the grenade over the wall."

"Like the zodiac sign?' Percy asked. 'I'm a Leo.''No, stupid,' Leo said, 'I'm a Leo. You're a Percy."

"And you, Percy, are my favorite son."

"Etiquette tip: If you're looking for the right time to leave a party, when the host yells, "No one leaves here alive," that's your cue."

"Percy, we're going to Polyphemus' island! Polyphemus is an S-i-k...a C-y-k..." She stamped her foot in frustration. As smart as she was, Annabeth was dyslexic, too. We could've been there all night while she tried to spell Cyclops. "You know what I mean!"

"You can't plan for feelings. You have to accept that. Let it scare you. Trust that it'll be okay anyway."

"Then Percy let go of his tiny ledge, and together, holding hands, he and Annabeth fell into the endless darkness."

"Annabeth realized that if six of them went on these two quests, it would leave Percy alone on the ship with Coach Hedge, which was maybe not a situation a caring girlfriend should put him in. Nor was she eager to let Percy out of her sight again-not after they'd been apart for so many months."

"Tyson- "Cash? Like...green paper?"Percy- "Yeah."Tyson- "Like the kind in duffel bags?"Percy-"Yeah, but we lost those bags days a-g-g--." "Tyson! How did you--"Tyson- "Thought it was a feed bag for Rainbow. Found it floating in sea, but only paper inside. Sorry."

"After the satyrs filed in to dinner, the Hermes cabin brought up the rear. They were always the biggest cabin. Last summer it had been led by Luke, the guy who fought with Thalia and Annabeth on top of Half-Blood Hill. For a while, before Poseidon had claimed me, I'd lodged in the Hermes cabin. Luke had befriended me...and then he'd tried to kill me."

"Ah, Senor Zhang," Leo said, "you know how you're always saying, 'Leo, you are the only true genius among demigods'?""I'm pretty sure I never said that."

"You can't just abandon your family because they did something horrible. You've done horrible things to them too."

"Stop!" he yelled at the others. "Multigrain fighting is not allowed!"

"Jason's heart lifted when he saw Nico di Angelo on the front lines with the Greeks, slashing his way through a crowd of two-headed men."

"Taken together, it's almost a sure sign. The letters float off the page when you read, right? That's because your mind is hardwired for ancient Greek. And the ADHD-you're impulsive, can't sit still in the classroom. That's your battlefield reflexes. In a real fight, they'd keep you alive. As for the attention problems, that's because you see too much, Percy, not too little. Your senses are better than a regular mortal's."

"Oh, yeah?" Leo growled. "Well, maybe you got the smoke, buddy, but I've got the fire."

"She'd also called me brave...unless she was talking to the catfish."

"Lord Bacchus, do you remember me? I helped you with that missing leopard in Sonoma." Bacchus scratched his stubbly chin. "Ah... yes. John Green." "Jason Grace.""Whatever," the god said."

"Percy!' Annabeth scolded. 'You just opened another Monster Doughnut shop somewhere!"

"Seeing them assembled in Tartarus, Percy felt as hopeless as the spirits in the River Cocytus. So what if he was a hero? So what if he did something brave? Evil was always here, regenerating, bubbling under the surface. Percy was no more than a minor annoyance to these immortal beings. They just had to outwait him. Someday, Percy's sons or daughters might have to face them all over again."

"Percy! he bellowed. He dropped his broom and ran at me. If you've never been charged by an enthusiastic Cyclops wearing a flowered apron and rubber cleaning gloves, I'm telling you, it'll wake you up quick."

"People are more difficult to work with than machines. And when you break a person, he can't be fixed."

"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."

"You're a stalker with hooves.""I am not! I followed her to the Big House and hid in a bush and watched the whole thing."
