Prologue

I knew what I had to do.

And yet, here I am. What is this crap? I'm not going to hitch-hike all the way to Philadelphia to find some kid who doesn't exist, and even if they do exist, what do I care?

Yeah, well, that's what I told myself. In reality, I would never disobey orders. I'm too scared.

My name is Thalia. I'm sixteen years old and I think I should warn you, right off the bat, that I'm not normal, not even by demigod standards. For one thing, everyone wants to kill me, and for another, I am partially immortal. Glad we got that cleared up.

Yeah, so this kid that allegedly lives in Philly and might not even be real: his name is Andrew Moore. Allegedly. And he's allegedly a half-blood. Gee, you don't say?

Lady Artemis thinks that, for some reason, he's been ignored by almost everyone: gods, satyrs, monsters, other demigods…that's why he's sixteen and still hasn't been claimed or even heard of at camp. And she wants me to find him. Great. Great.

I can't see what's so special about this Andrew kid that he's been ignored for half his life, good Zeus, he might not even be a half-blood. He might not even exist. What happens if I get to Philadelphia and I can't even find him? What happens if he was killed by monsters by then, or—or—!

I don't even know why I'm freaking out. Something just doesn't feel right about this. I need to calm down.

CALM DOWN?

Dear gods.
