“Hey, can I see that sword you were using?"
I showed him Riptide, and explained how it turned from a pen into a sword just by uncapping it.
"Cool! Does it ever run out of ink?"
"Um, well, I don't actually write with it."
"Are you really the son of Poseidon?"
"Well, yeah."
"Can you surf really well, then?"
I looked at Grover, who was trying hard not to laugh.
"Jeez, Nico," I said. "I've never really tried."
He went on asking questions. Did I fight a lot with Thalia, since she was a daughter of Zeus? (I didn't answer that one.) If Annabeth's mother was Athena, the goddess of wisdom, then why didn't Annabeth know better than to fall off a cliff? (I tried not to strangle Nico for asking that one.) Was Annabeth my girlfriend? (At this point, I was ready to stick the kid in a meat-flavored sack and throw him to the wolves.)”

“The way to beat Luke," he said. "If I'm right, it's the only way you'll stand a chance."
I took a deep breath. "Okay. I'm listening."
Nico glanced inside my room. His eyebrows furrowed.
"Is that...is that blue birthday cake?"
He sounded hungry, maybe a little wistful. I wondered if the poor kid had ever had a birthday party, or if he'd ever even been invited to one.
:Come inside for cake and ice cream," I said. "It sounds like we've got a lot to talk about.”
