The Sea of Monsters (5 page)

"I, Annabeth Chase, give you permission to enter camp!"

Thunder shook the hillside. Suddenly Tyson was there, barreling toward me, yelling: "Percy needs help!"

Before I could tell him no, he dove between me and the bull just as it unleashed a nuclear firestorm.

"Tyson!" I yelled.

The blast swirled around him like a red tornado. I could only see the black silhouette of his body. I knew with hor-rible certainty that my friend had just been turned into a column of ashes.

But when the fire died, Tyson was still standing there, completely unharmed. Not even his grungy clothes were scorched. The bull must've been as surprised as I was, because before it could unleash a second blast, Tyson balled his fists and slammed them into the bull's face.

"BAD COW!"

His fists made a crater where the bronze bull's snout used to be. Two small columns of flame shot out of its ears. Tyson hit it again, and the bronze crumpled under his hands like aluminum foil. The bull's face now looked like a sock puppet pulled inside out.

"Down!" Tyson yelled.

The bull staggered and fell on its back. Its legs moved feebly in the air, steam coming out of its ruined head in odd places.

Annabeth ran over to check on me.

My ankle felt like it was filled with acid, but she gave me some Olympian nectar to drink from her canteen, and I immediately started to feel better. There was a burning smell that I later learned was me. The hair on my arms had been completely singed off.

"The other bull?" I asked.

Annabeth pointed down the hill. Clarisse had taken care of Bad Cow Number Two. She'd impaled it through the back leg with a celestial bronze spear. Now, with its snout half gone and a huge gash in its side, it was trying to run in slow motion, going in circles like some kind of merry-go-round animal.

Clarisse pulled off her helmet and marched toward us. A strand of her stringy brown hair was smoldering, but she didn't seem to notice. "You—ruin—everything!" she yelled at me. "I had it under control!"

I was too stunned to answer. Annabeth grumbled, "Good to see you too, Clarisse."

"Argh!" Clarisse screamed. "Don't ever, EVER try sav-ing me again!"

"Clarisse," Annabeth said, "you've got wounded campers."

That sobered her up. Even Clarisse cared about the soldiers under her command.

"I'll be back," she growled, then trudged off to assess the damage.

I stared at Tyson. "You didn't die."

Tyson looked down like he was embarrassed. "I am sorry. Came to help. Disobeyed you."

"My fault," Annabeth said. "I had no choice. I had to let Tyson cross the boundary line to save you. Otherwise, you would've died."

"Let him cross the boundary line?'" I asked. "But—"

"Percy," she said, "have you ever looked at Tyson closely? I mean ... in the face. Ignore the Mist, and really look at him."

The Mist makes humans see only what their brains can process ... I knew it could fool demigods too, but...

I looked Tyson in the face. It wasn't easy. I'd always had trouble looking directly at him, though I'd never quite understood why. I'd thought it was just because he always had peanut butter in his crooked teeth. I forced myself to focus at his big lumpy nose, then a little higher at his eyes.

No, not eyes.

One eye. One large, calf-brown eye, right in the middle of his forehead, with thick lashes and big tears trickling down his cheeks on either side.

"Tyson," I stammered. "You're a ..."

"Cyclops," Annabeth offered. "A baby, by the looks of him. Probably why he couldn't get past the boundary line as easily as the bulls. Tyson's one of the homeless orphans."

"One of the what?"

"They're in almost all the big cities," Annabeth said distastefully. "They're ... mistakes, Percy. Children of nature spirits and gods ... Well, one god in particular, usually ... and they don't always come out right. No one wants them. They get tossed aside. They grow up wild on the streets. I don't know how this one found you, but he obviously likes you. We should take him to Chiron, let him decide what to do."

"But the fire. How—"

"He's a Cyclops." Annabeth paused, as if she were remembering something unpleasant. "They work the forges of the gods. They have to be immune to fire. That's what I was trying to tell you."

I was completely shocked. How had I never realized what Tyson was?

But I didn't have much time to think about it just then. The whole side of the hill was burning. Wounded heroes needed attention. And there were still two banged-up bronze bulls to dispose of, which I didn't figure would fit in our normal recycling bins.

Clarisse came back over and wiped the soot off her forehead. "Jackson, if you can stand, get up. We need to carry the wounded back to the Big House, let Tantalus know what's happened."

"Tantalus?" I asked.

"The activities director," Clarisse said impatiently.

"Chiron is the activities director. And where's Argus? He's head of security. He should be here."

Clarisse made a sour face. "Argus got fired. You two have been gone too long. Things are changing."

"But Chiron ... He's trained kids to fight monsters for over three thousand years. He can't just be gone. What hap-pened?"

"That happened," Clarisse snapped.

She pointed to Thalia's tree.

Every camper knew the story behind the tree. Six years ago, Grover, Annabeth, and two other demigods named Thalia and Luke had come to Camp Half-Blood chased by an army of monsters. When they got cornered on top of this hill, Thalia, a daughter of Zeus, had made her last stand here to give her friends time to reach safety. As she was dying, her father, Zeus, took pity on her and changed her into a pine tree. Her spirit had reinforced the magic borders of the camp, protecting it from monsters. The pine had been here ever since, strong and healthy.

But now, its needles were yellow. A huge pile of dead ones littered the base of the tree. In the center of the trunk, three feet from the ground, was a puncture mark the size of a bullet hole, oozing green sap.

A sliver of ice ran through my chest. Now I understood why the camp was in danger. The magical borders were fail-ing because Thalia's tree was dying.

Someone had poisoned it.

Ever come home and found your room messed up? Like some helpful person (hi, Mom) has tried to "clean" it, and suddenly you can't find anything? And even if nothing is missing, you get that creepy feeling like somebody's been looking through your private stuff and dusting everything with lemon furniture polish?

That's kind of the way I felt seeing Camp Half-Blood again.

On the surface, things didn't look all that different. The Big House was still there with its blue gabled roof and its wraparound porch. The strawberry fields still baked in the sun. The same white-columned Greek buildings were scattered around the valley—the amphitheater, the combat arena, the dining pavilion overlooking Long Island Sound. And nestled between the woods and the creek were the same cabins—a crazy assortment of twelve buildings, each repre-senting a different Olympian god.

But there was an air of danger now. You could tell something was wrong. Instead of playing volleyball in the sandpit, counselors and satyrs were stockpiling weapons in the tool shed. Dryads armed with bows and arrows talked nervously at the edge of the woods. The forest looked sickly, the grass in the meadow was pale yellow, and the fire marks on Half-Blood Hill stood out like ugly scars.

Somebody had messed with my favorite place in the world, and I was not ... well, a happy camper.

As we made our way to the Big House, I recognized a lot of kids from last summer. Nobody stopped to talk. Nobody said, "Welcome back." Some did double takes when they saw Tyson, but most just walked grimly past and carried on with their duties—running messages, toting swords to sharpen on the grinding wheels. The camp felt like a military school. And believe me, I know. I've been kicked out of a couple.

None of that mattered to Tyson. He was absolutely fas-cinated by everything he saw.

"Whasthat!" he gasped.

"The stables for pegasi," I said. "The winged horses."

"Whasthat!"

"Um ... those are the toilets."

"Whasthat!"

"The cabins for the campers. If they don't know who your Olympian parent is, they put you in the Hermes cabin—that brown one over there—until you're deter-mined. Then, once they know, they put you in your dad or mom's group."

He looked at me in awe. "You ... have a cabin?"

"Number three." I pointed to a low gray building made of sea stone.

"You live with friends in the cabin?"

"No. No, just me." I didn't feel like explaining. The embarrassing truth: I was the only one who stayed in that cabin because I wasn't supposed to be alive. The "Big Three" gods—Zeus, Poseidon, and Hades—had made a pact after World War II not to have any more children with mortals. We were more powerful than regular half-bloods. We were too unpredictable. When we got mad we tended to cause problems ... like World War II, for instance. The "Big Three" pact had only been broken twice—once when Zeus sired Thalia, once when Poseidon sired me. Neither of us should've been born.

Thalia had gotten herself turned into a pine tree when she was twelve. Me ... well, I was doing my best not to fol-low her example. I had nightmares about what Poseidon might turn me into if I were ever on the verge of death— plankton, maybe. Or a floating patch of kelp.

When we got to the Big House, we found Chiron in his apartment, listening to his favorite 1960s lounge music while he packed his saddlebags. I guess I should mention—Chiron is a centaur. From the waist up he looks like a reg-ular middle-aged guy with curly brown hair and a scraggly beard. From the waist down, he's a white stallion. He can pass for human by compacting his lower half into a magic wheelchair. In fact, he'd passed himself off as my Latin teacher during my sixth-grade year. But most of the time, if the ceilings are high enough, he prefers hanging out in full centaur form.

As soon as we saw him, Tyson froze. "Pony!" he cried in total rapture.

Chiron turned, looking offended. "I beg your pardon?"

Annabeth ran up and hugged him. "Chiron, what's happening? You're not ... leaving?" Her voice was shaky. Chiron was like a second father to her.

Chiron ruffled her hair and gave her a kindly smile. "Hello, child. And Percy, my goodness. You've grown over the year!"

I swallowed. "Clarisse said you were ... you were ..."

"Fired." Chiron's eyes glinted with dark humor. "Ah, well, someone had to take the blame. Lord Zeus was most upset. The tree he'd created from the spirit of his daughter, poisoned! Mr. D had to punish someone."

"Besides himself, you mean," I growled. Just the thought of the camp director, Mr. D, made me angry.

"But this is crazy!" Annabeth cried. "Chiron, you couldn't have had anything to do with poisoning Thalia's tree!"

"Nevertheless," Chiron sighed, "some in Olympus do not trust me now, under the circumstances."

"What circumstances?" I asked.

Chiron's face darkened. He stuffed a Latin-English dictionary into his saddlebag while the Frank Sinatra music oozed from his boom box.

Tyson was still staring at Chiron in amazement. He whimpered like he wanted to pat Chiron's flank but was afraid to come closer. "Pony?"

Chiron sniffed. "My dear young Cyclops! I am a centaur."

"Chiron," I said. "What about the tree? What hap-pened?"

He shook his head sadly. "The poison used on Thalia's pine is something from the Underworld, Percy. Some venom even I have never seen. It must have come from a monster quite deep in the pits of Tartarus."

"Then we know who's responsible. Kro—"

"Do not invoke the titan lord's name, Percy. Especially not here, not now."

"But last summer he tried to cause a civil war in Olympus! This has to be his idea. He'd get Luke to do it, that traitor."

"Perhaps," Chiron said. "But I fear I am being held responsible because I did not prevent it and I cannot cure it. The tree has only a few weeks of life left unless ..."

"Unless what?" Annabeth asked.

"No," Chiron said. "A foolish thought. The whole valley is feeling the shock of the poison. The magical borders are deteriorating. The camp itself is dying. Only one source of magic would be strong enough to reverse the poison, and it was lost centuries ago."

"What is it?" I asked. "We'll go find it!"

Chiron closed his saddlebag. He pressed the stop but-ton on his boom box. Then he turned and rested his hand on my shoulder, looking me straight in the eyes. "Percy, you must promise me that you will not act rashly. I told your mother I did not want you to come here at all this summer. It's much too dangerous. But now that you are here, stay here. Train hard. Learn to fight. But do not leave."

"Why?" I asked. "I want to do something! I can't just let the borders fail. The whole camp will be—"

"Overrun by monsters," Chiron said. "Yes, I fear so. But you must not let yourself be baited into hasty action! This could be a trap of the titan lord. Remember last summer! He almost took your life."

It was true, but still, I wanted to help so badly. I also wanted to make Kronos pay. I mean, you'd think the titan lord would've learned his lesson eons ago when he was over-thrown by the gods. You'd think getting chopped into a mil-lion pieces and cast into the darkest part of the Underworld would give him a subtle clue that nobody wanted him around. But no. Because he was immortal, he was still alive down there in Tartarus—suffering in eternal pain, hunger-ing to return and take revenge on Olympus. He couldn't act on his own, but he was great at twisting the minds of mor-tals and even gods to do his dirty work.

The poisoning had to be his doing. Who else would be so low as to attack Thalia's tree, the only thing left of a hero who'd given her life to save her friends?

Annabeth was trying hard not to cry. Chiron brushed a tear from her cheek. "Stay with Percy, child," he told her. "Keep him safe. The prophecy—remember it!"

"I—I will."
