“Love conquers all," Aphrodite promised. "Look at Helen and Paris. Did they let anything come between them?"
"Didn't they start the Trojan War and get thousands of people killed?"

“I nodded, looking at Rachel with respect. "You hit the Lord of the Titans in the eye with a blue plastic hairbrush.”

“What if it lines up like it did in the Trojan War ... Athena versus Poseidon?"
"I don't know. But I just know that I'll be fighting next to you."

“In a way, it's nice to know that there are Greek gods out there, because you have somebody to blame when things go wrong. For instance, when you're walking away from a bus that's just been attacked by monster hags and blown up by lightning, and it's raining on top of everything else, most people might think that's just really bad luck; when you're a half-blood, you understand that some devine force is really trying to mess up your day.”
