"Here you go, Percy," Luke said, handing me a platter of smoked brisket.

I loaded my plate and was about to take a big bite when I noticed everybody getting up, carrying their plates toward the fire in the center of the pavilion. I wondered if they were going for dessert or something.

"Come on," Luke told me.

As I got closer, I saw that everyone was taking a portion of their meal and dropping it into the fire, the ripest strawberry, the juiciest slice of beef, the warmest, most buttery roll.

Luke murmured in my ear, "Burnt offerings for the gods. They like the smell."

"You're kidding."

His look warned me not to take this lightly, but I couldn't help wondering why an immortal, all-powerful being would like the smell of burning food.

Luke approached the fire, bowed his head, and tossed in a cluster of fat red grapes. "Hermes."

I was next.

I wished I knew what god's name to say.

Finally, I made a silent plea. Whoever you are, tell me. Please.

I scraped a big slice of brisket into the flames.

When I caught a whiff of the smoke, I didn't gag.

It smelled nothing like burning food. It smelled of hot chocolate and fresh-baked brownies, hamburgers on the grill and wildflowers, and a hundred other good things that shouldn't have gone well together, but did. I could almost believe the gods could live off that smoke.

When everybody had returned to their seats and finished eating their meals, Chiron pounded his hoof again for our attention.

Mr. D got up with a huge sigh. "Yes, I suppose I'd better say hello to all you brats. Well, hello. Our activities director, Chiron, says the next capture the flag is Friday. Cabin five presently holds the laurels."

A bunch of ugly cheering rose from the Ares table.

"Personally," Mr. D continued, "I couldn't care less, but congratulations. Also, I should tell you that we have a new camper today. Peter Johnson."

Chiron murmured something.

"Er, Percy Jackson," Mr. D corrected. "That's right. Hurrah, and all that. Now run along to your silly campfire. Go on."

Everybody cheered. We all headed down toward the amphitheater, where Apollo's cabin led a sing-along. We sang camp songs about the gods and ate s'mores and joked around, and the funny thing was, I didn't feel that anyone was staring at me anymore. I felt that I was home.

Later in the evening, when the sparks from the campfire were curling into a starry sky, the conch horn blew again, and we all filed back to our cabins. I didn't realize how exhausted I was until I collapsed on my borrowed sleeping bag.

My fingers curled around the Minotaur's horn. I thought about my mom, but I had good thoughts: her smile, the bedtime stories she would read me when I was a kid, the way she would tell me not to let the bedbugs bite.

When I closed my eyes, I fell asleep instantly.

That was my first day at Camp Half-Blood.

I wish I'd known how briefly I would get to enjoy my new home.

The next few days I settled into a routine that felt almost normal, if you don't count the fact that I was getting lessons from satyrs, nymphs, and a centaur.

Each morning I took Ancient Greek from Annabeth, and we talked about the gods and goddesses in the present tense, which was kind of weird. I discovered Annabeth was right about my dyslexia: Ancient Greek wasn't that hard for me to read. At least, no harder than English. After a couple of mornings, I could stumble through a few lines of Homer without too much headache.

The rest of the day, I'd rotate through outdoor activities, looking for something I was good at. Chiron tried to teach me archery, but we found out pretty quick I wasn't any good with a bow and arrow. He didn't complain, even when he had to desnag a stray arrow out of his tail.

Foot racing? No good either. The wood-nymph instructors left me in the dust. They told me not to worry about it. They'd had centuries of practice running away from lovesick gods. But still, it was a little humiliating to be slower than a tree.

And wrestling? Forget it. Every time I got on the mat, Clarisse would pulverize me.

"There's more where that came from, punk," she'd mumble in my ear.

The only thing I really excelled at was canoeing, and that wasn't the kind of heroic skill people expected to see from the kid who had beaten the Minotaur.

I knew the senior campers and counselors were watching me, trying to decide who my dad was, but they weren't having an easy time of it. I wasn't as strong as the Ares kids, or as good at archery as the Apollo kids. I didn't have Hephaestus's skill with metalwork or—gods forbid— Dionysus's way with vine plants. Luke told me I might be a child of Hermes, a kind of jack-of-all-trades, master of none. But I got the feeling he was just trying to make me feel better. He really didn't know what to make of me either.

Despite all that, I liked camp. I got used to the morning fog over the beach, the smell of hot strawberry fields in the afternoon, even the weird noises of monsters in the woods at night. I would eat dinner with cabin eleven, scrape part of my meal into the fire, and try to feel some connection to my real dad. Nothing came. Just that warm feeling I'd always had, like the memory of his smile. I tried not to think too much about my mom, but I kept wondering: if gods and monsters were real, if all this magical stuff was possible, surely there was some way to save her, to bring her back….

I started to understand Luke's bitterness and how he seemed to resent his father, Hermes. So okay, maybe gods had important things to do. But couldn't they call once in a while, or thunder, or something? Dionysus could make Diet Coke appear out of thin air. Why couldn't my dad, whoever he was, make a phone appear?

Thursday afternoon, three days after I'd arrived at Camp Half-Blood, I had my first sword-fighting lesson. Everybody from cabin eleven gathered in the big circular arena, where Luke would be our instructor.

We started with basic stabbing and slashing, using some straw-stuffed dummies in Greek armor. I guess I did okay. At least, I understood what I was supposed to do and my reflexes were good.

The problem was, I couldn't find a blade that felt right in my hands. Either they were too heavy, or too light, or too long. Luke tried his best to fix me up, but he agreed that none of the practice blades seemed to work for me.

We moved on to dueling in pairs. Luke announced he would be my partner, since this was my first time.

"Good luck," one of the campers told me. "Luke's the best swordsman in the last three hundred years."

"Maybe he'll go easy on me," I said.

The camper snorted.

Luke showed me thrusts and parries and shield blocks the hard way. With every swipe, I got a little more battered and bruised. "Keep your guard up, Percy," he'd say, then whap me in the ribs with the flat of his blade. "No, not that far up!" Whap! "Lunge!" Whap! "Now, back!" Whap!

By the time he called a break, I was soaked in sweat. Everybody swarmed the drinks cooler. Luke poured ice water on his head, which looked like such a good idea, I did the same.

Instantly, I felt better. Strength surged back into my arms. The sword didn't feel so awkward.

"Okay, everybody circle up!" Luke ordered. "If Percy doesn't mind, I want to give you a little demo."

Great, I thought. Let's all watch Percy get pounded.

The Hermes guys gathered around. They were suppressing smiles. I figured they'd been in my shoes before and couldn't wait to see how Luke used me for a punching bag. He told everybody he was going to demonstrate a disarming technique: how to twist the enemy's blade with the flat of your own sword so that he had no choice but to drop his weapon.
