“Don't underestimate Camp Half-Blood.”

“Yeah, flattering." Percy raised Riptide. "But actually I`m the son of Poseidon. I`m from Camp Half-Blood.”

“He had arrived at Camp Half-Blood thanks to Apollo. Now, on what would likely be his last day at camp, he was stuck with a son of Apollo.
‘Whatever,’ Nico said. ‘But we have to hurry. And you’ll follow my lead.”

“In that moment, he chose Greek. He threw in his lot with Camp Half-Blood-and the horses changed. The storm clouds inside burned away, leaving nothing but red dust and shimmering heat, like mirages on the Sahara.”

“I don't care what your nose says! The last time you smelled half-blood, it turned out to be a meatloaf sandwich!"
"Meatloaf sandwiches are good! But this is a half-blood scent, I swear. They are on board!"
"Bah, your brain isn't on board!”

“So, great. This is Camp…what do you call it? Camp Fish-Blood?”
Aphros frowned. “I hope that was a joke. This is Camp __________.” He made a sound that was a series of sonar pings and hisses.”

“The meeting was like a war council with donuts. Then again, back at Camp Half-Blood they used to have their most serious discussions around the Ping-Pong table in the rec room with crackers and Cheez Whiz, so Percy felt right at home.”

“My father, Zeus, did not love me. The demigods at Camp Half-Blood did not love me. Python and the Beast and his comrades at Triumvirate Holdings did not love me. It was almost enough to make me question my self-worth.

No, no. That was crazy talk.”

“Rachel: You're a half-blood, too?
Annabeth: Shhh! Just announce it to the world, how about?
Rachel: Okay. Hey, everybody! These two aren't human! They're half Greek god!… They don't seem to care.”

“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.”
