The Lightning Thief
"The gods are busy. They have a lot of kids and they don't always…Well, sometimes they don't care about us, Percy. They ignore us."
I thought about some of the kids I'd seen in the Hermes cabin, teenagers who looked sullen and depressed, as if they were waiting for a call that would never come. I'd known kids like that at Yancy Academy, shuffled off to boarding school by rich parents who didn't have the time to deal with them. But the gods should behave better. (7.46-47)
"Don't worry about it, Percy. The campers here, they're mostly good people. After all, we're extended family, right? We take care of each other." (7.97)
"About sixty years ago, after World War II, the Big Three agreed they wouldn't sire any more heroes. Their children were just too powerful. They were affecting the course of human events too much, causing too much carnage. World War II, you know, that was basically a fight between the sons of Zeus and Poseidon on one side, and the sons of Hades on the other. The winning side, Zeus and Poseidon, made Hades swear an oath with them: no more affairs with mortal women. They all swore on the River Styx." (8.64)
