Wait, what!?!

Magnus was supposed to be back at Camp. But there was no mistaking him, somehow, Magnus Chase had found us.

When Annabeth finally released the poor guy it clearly wasn't out of respect for his need to breathe, she immediately started yelling at him.

"How did you get here?"

"I got a bus"

"How did you find us?"

"I followed the scraps of aluminum cans and burning wreckage."

"So not funny, does Chiron know your with us?"

"no"

They continued on like that for several minutes before Grover intervened. "But Magnus, what are you DOING here?"

"I'm going to join the quest."

The three of us looked at each other, Annabeth turned back to her cousin. "Magnus, you know the rules, three people is the max for a quest. Unless you got a prophecy from the oracle you cant come with us. You could cause all sorts of bad luck." She looked really sad as she said it, but I saw the steel resolve in her eyes.

Magnus scowled at her, "I'm not letting you do this on your own."

Annabeth was glaring too. "I don't need you here to babysit me. I can take care of myself!"

She spun around and started to walk away but Magnus grabbed her arm.

"But what if you can't, What happens when some monster gets the jump on you? What happens then, It'll be all fine and dandy for you, but Annie what about ME?" His voice cracked on the last word.

"you're all I have left. Do you think I could just go back and sleep in that bunk in cabin eleven, if I knew I was here and let you go off without me? Remember family, Annabeth? We all promised, so don't leave us alone, don't leave me alone. Let me come."

I looked away, Magnus and Annabeth both had tears in their eyes, and Magnus's chest was heaving. This felt like a private moment. Grover spoke in a quiet voice.

"Let him come."

"But Grover, he doesn't belong on this quest."

Her words sparked something in my memory. A line of the prophecy came back to me. You will be joined by the one who does not belong.

I wasn't completely sure that this is what the line meant, but I wasn't about to turn down extra help.

"Guys, I think Magnus is supposed to join us. There was a line in the prophecy 'you will be joined by the one who doesn't belong' I think it could be referring to the fact that Magnus technically doesn't belong on the quest."

Magnus gave me a small smile. Annabeth turned her glare on me, "Are you sure that's what the line said?"

"Yes"

Grover spoke before she could start arguing with me. "Well, he cant leave now anyways, lets just sleep on it."

Magnus Grover and I settled together. Annabeth sat on the other side of the clearing, clearly annoyed but every so often she would look at Magnus and her face would soften. I could tell she was happy to see him, even if she pretended, she wasn't.

&&&&&&&&

In my dreams, I stood in a dark cavern before a gaping pit. Gray mist creatures churned all around me, whispering rags of smoke that I somehow knew were the spirits of the dead.

They tugged at my clothes, trying to pull me back, but I felt compelled to walk forward to the very edge of the chasm.

Looking down made me dizzy.

The pit yawned so wide and was so completely black, I knew it must be bottomless. Yet I had a feeling that something was trying to rise from the abyss, something huge and evil.

The little hero, an amused voice echoed far down in the darkness. Too weak, too young, but perhaps you will do.

The voice felt ancient—cold and heavy. It wrapped around me like sheets of lead.

They have misled you, boy, it said. Barter with me. I will give you what you want.

A shimmering image hovered over the void: my mother, frozen at the moment she'd dissolved in a shower of gold. Her face was distorted with pain, as if the Minotaur were still squeezing her neck. Her eyes looked directly at me, pleading: Go!

I tried to cry out, but my voice wouldn't work.

Cold laughter echoed from the chasm.

An invisible force pulled me forward. It would drag me into the pit unless I stood firm.

Help me rise, boy. The voice became hungrier. Bring me the bolt. Strike a blow against the treacherous gods!

The spirits of the dead whispered around me, No! Wake!

The image of my mother began to fade. The thing in the pit tightened its unseen grip around me.

I realized it wasn't interested in pulling me in. It was using me to pull itself out.

Good, it murmured. Good.

Wake! the dead whispered. Wake!

Someone was shaking me.

My eyes opened, and it was daylight.

"Well," Annabeth said, "the zombie lives."

I was trembling from the dream. I could still feel the grip of the chasm monster around my chest. "How long was I asleep?"

"Long enough for Magnus to cook breakfast." Annabeth tossed me a bag of nacho-flavored corn chips from Aunty Em's snack bar. "And Grover went exploring. Look, he found a friend."

My eyes had trouble focusing.

Grover was sitting cross-legged on a blanket with something fuzzy in his lap, a dirty, unnaturally pink stuffed animal.

No. It wasn't a stuffed animal. It was a pink poodle.

Magnus was sitting next to Grover and he was petting the small dog.

The poodle yapped at me suspiciously. Grover said, "No, he's not."

I blinked. "Are you ... talking to that thing?"

The poodle growled.

"This thing," Grover warned, "is our ticket west. Be nice to him."

"You can talk to animals?"

Grover ignored the question. "Percy, meet Gladiola. Gladiola, Percy."

I stared at Annabeth, figuring she'd crack up at this practical joke they were playing on me, but she looked deadly serious.

"I'm not saying hello to a pink poodle," I said. "Forget it."

"Percy," Annabeth said. "I said hello to the poodle, Magnus said hello to the poodle. You say hello to the poodle."

The poodle growled.

I said hello to the poodle.

Grover explained that he'd come across Gladiola in the woods and they'd struck up a conversation. The poodle had run away from a rich local family, who'd posted a 200 reward for his return. Gladiola didn't really want to go back to his family, but he was willing to if it meant helping Grover.

"How does Gladiola know about the reward?" I asked.

"He read the signs," Grover said. "Duh."

"Of course," I said. "Silly me."

"So we turn in Gladiola," Annabeth explained in her best strategy voice, "we get money, and we buy tickets to Los Angeles. Simple."

I thought about my dream—the whispering voices of the dead, the thing in the chasm, and my mother's face, shimmering as it dissolved into gold. All that might be waiting for me in the West.

"Not another bus," I said warily.

"No," Annabeth agreed.

She pointed downhill, toward train tracks I hadn't been able to see last night in the dark. "There's an Amtrak station half a mile that way. According to Gladiola, the westbound train leaves at noon."

&&&&&&&&&&

We spent two days on the Amtrak train, heading west through hills, over rivers, past amber waves of grain.

I tried to keep a low profile because my name and picture were splattered over the front pages of several East Coast newspapers. The Trenton Register-News showed a photo taken by a tourist as I got off the Greyhound bus. I had a wild look in my eyes. My sword was a metallic blur in my hands. It might've been a baseball bat or a lacrosse stick.

The picture's caption read:

Twelve-year-old Percy Jackson, wanted for questioning in the Long Island disappearance of his mother two weeks ago, is shown here fleeing from the bus where he accosted several elderly female passengers. The bus exploded on an east New Jersey roadside shortly after Jackson fled the scene. Based on eyewitness accounts, police believe the boy may be traveling with two teenage accomplices. His stepfather, Gabe Ugliano, has offered a cash reward for information leading to his capture.

"Don't worry," Annabeth told me. "Mortal police could never find us." But she didn't sound so sure.

The rest of the day I spent alternately pacing the length of the train (because I had a really hard time sitting still) or looking out the windows.

After some half-hearted protests from Annabeth, Magnus had joined us. Although he wasn't officially part of the quest.

Our reward money for returning Gladiola the poodle had only been enough to purchase tickets as far as Denver. We couldn't get berths in the sleeper car, so we dozed in our seats. My neck got stiff. I tried not to drool in my sleep, since Annabeth was sitting right next to me.

Magnus and Grover were sleeping. Grover kept snoring and bleating and waking me up. Once, he shuffled around and his fake foot fell off. Annabeth and I had to stick it back on before any of the other passengers noticed.

"So," Annabeth asked me, once we'd gotten Grover's sneaker readjusted. "Who wants your help?"

"What do you mean?"

"When you were asleep just now, you mumbled, 'I won't help you.' Who were you dreaming about?"

I was reluctant to say anything. It was the second time I'd dreamed about the evil voice from the pit. But it bothered me so much I finally told her.

Annabeth was quiet for a long time. "That doesn't sound like Hades. He always appears on a black throne, and he never laughs."

"He offered my mother in trade. Who else could do that?"

"I guess ... if he meant, 'Help me rise from the Underworld.' If he wants war with the Olympians. But why ask you to bring him the master bolt if he already has it?"

I shook my head, wishing I knew the answer. I thought about what Grover had told me, that the Furies on the bus seemed to have been looking for something.

Where is it? Where?

Maybe Grover sensed my emotions. He snorted in his sleep, muttered something about vegetables, and turned his head.

Annabeth readjusted his cap so it covered his horns. "Percy, you can't barter with Hades. You know that, right? He's deceitful, heartless, and greedy. I don't care if his Kindly Ones weren't as aggressive this time—"

"This time?" I asked. "You mean you've run into them before?"

Her hand crept up to her necklace. She fingered a glazed white bead painted with the image of a pine tree, one of her clay end-of-summer tokens. "Let's just say I've got no love for the Lord of the Dead. You can't be tempted to make a deal for your mom."

"What would you do if it was your dad?"

"That's easy," she said. "I'd leave him to rot."

"You're not serious?"

Annabeth's gray eyes fixed on me. She wore the same expression she'd worn in the woods at camp, the moment she drew her sword against the hellhound. "My dad's resented me since the day I was born, Percy," she said. "He never wanted a baby. When he got me, he asked Athena to take me back and raise me on Olympus because he was too busy with his work. She wasn't happy about that. She told him heroes had to be raised by their mortal parent."

"But how ... I mean, I guess you weren't born in a hospital..."

"I appeared on my father's doorstep, in a golden cradle, carried down from Olympus by Zephyr the West Wind. You'd think my dad would remember that as a miracle, right? Like, maybe he'd take some digital photos or something. But he always talked about my arrival as if it were the most inconvenient thing that had ever happened to him. When I was five he got married and totally forgot about Athena. He got a 'regular' mortal wife, and had two 'regular' mortal kids, and tried to pretend I didn't exist."

I stared out the train window. The lights of a sleeping town were drifting by. I wanted to make Annabeth feel better, but I didn't know how.

"My mom married a really awful guy," I told her. "Grover said she did it to protect me, to hide me in the scent of a human family. Maybe that's what your dad was thinking."

Annabeth kept worrying at her necklace. She was pinching the gold college ring that hung with the beads. It occurred to me that the ring must be her father's. I wondered why she wore it if she hated him so much.

"He doesn't care about me," she said. "His wife—my stepmom—treated me like a freak. She wouldn't let me play with her children. My dad went along with her. Whenever something dangerous happened—you know, something with monsters—they would both look at me resentfully, like, 'How dare you put our family at risk. Then my Dad got a phone call, someone had broken into his sisters apartment and she was killed – but her six year old son had survived by hiding under the bed. He took Magnus in but my stepmom wasn't happy about it. After a few weeks I realized Magnus could see the monsters, he'd never known his father, so I assumed he was a demigod like me. I had thought things might get better with Magnus there, they only got worse. Finally, I took the hint. We weren't wanted. And so we ran away."

"How old were you?"

"Same age as when we started camp. Six and Seven."

"But ... you couldn't have gotten all the way to Half-Blood Hill by yourself."

"Not alone, no. Athena watched over us, guided me toward help. We made a couple of unexpected friends who took care of us, for a short time, anyway."

I wanted to ask what happened, but Annabeth seemed lost in sad memories. So I listened to the sound of Grover snoring and gazed out the train windows as the dark fields of Ohio raced by.

&&&&&&&&

Toward the end of our second day on the train, June 13, eight days before the summer solstice, we passed through some golden hills and over the Mississippi River into St. Louis. Annabeth craned her neck to see the Gateway Arch, which looked to me like a huge shopping bag handle stuck on the city.

"I want to do that," she sighed.

"What?" I asked.

"Build something like that. You ever see the Parthenon, Percy?"

"Only in pictures."

"Someday, I'm going to see it in person. I'm going to build the greatest monument to the gods, ever. Something that'll last a thousand years."

I laughed. "You? An architect?"

I don't know why, but I found it funny. Just the idea of Annabeth trying to sit quietly and draw all day.

Her cheeks flushed. "Yes, an architect. Athena expects her children to create things, not just tear them down, like a certain god of earthquakes I could mention."

I watched the churning brown water of the Mississippi below.

"Sorry," Annabeth said. "That was mean."

"Can't we work together a little?" I pleaded. "I mean, didn't Athena and Poseidon ever cooperate?"

Annabeth had to think about it. "I guess ... the chariot," she said tentatively. "My mom invented it, but Poseidon created horses out of the crests of waves. So they had to work together to make it complete."

"Then we can cooperate, too. Right?"

"I suppose," she said at last.

We pulled into the Amtrak station downtown. The intercom told us we'd have a three-hour layover before departing for Denver.

Grover stretched. Before he was even fully awake, he said, "Food."

"Come on, goat boy," Annabeth said. "Sightseeing."

"Sightseeing?"

"The Gateway Arch," she said. "This may be my only chance to ride to the top. Are you coming or not?"

Grover, Magnus and I exchanged looks.

I wanted to say no, but I figured that if Annabeth was going, we couldn't very well let her go alone.

Grover shrugged. "As long as there's a snack bar without monsters."

The Arch was about a mile from the train station. Late in the day the lines to get in weren't that long. We threaded our way through the underground museum, looking at covered wagons and other junk from the 1800s. It wasn't all that thrilling, but Annabeth kept telling us interesting facts about how the Arch was built, and Magnus kept passing me jelly beans, so I was okay.

I kept looking around, though, at the other people in line. "You smell anything?" I murmured to Grover.

He took his nose out of the jelly-bean bag long enough to sniff. "Underground," he said distastefully. "Underground air always smells like monsters. Probably doesn't mean anything."

But something felt wrong to me. I had a feeling we shouldn't be here.

"Guys," I said. "You know the gods' symbols of power?"

Annabeth had been in the middle of reading about the construction equipment used to build the Arch, but she looked over. "Yeah?"

"Well, Hade—"

Magnus cleared his throat. "We're in a public place... You mean, our friend downstairs?"

"Um, right," I said. "Our friend way downstairs. Doesn't he have a hat like Annabeth's?"

"You mean the Helm of Darkness," Annabeth said. "Yeah, that's his symbol of power. I saw it next to his seat during the winter solstice council meeting."

"He was there?" I asked.

She nodded. "It's the only time he's allowed to visit Olympus—the darkest day of the year. But his helm is a lot more powerful than my invisibility hat, if what I've heard is true..."

"It allows him to become darkness," Magnus confirmed. "He can melt into shadow or pass through walls. He can't be touched, or seen, or heard. And he can radiate fear so intense it can drive you insane or stop your heart. Why do you think all rational creatures fear the dark?"

"But then ... how do we know he's not here right now, watching us?" I asked.

Annabeth and Magnus exchanged looks.

"We don't," Grover said.

"Thanks, that makes me feel a lot better," I said. "Got any blue jelly beans left?"

I'd almost mastered my jumpy nerves when I saw the tiny little elevator car we were going to ride to the top of the Arch, and I knew I was in trouble. I hate confined places. They make me nuts.

We got shoehorned into the car with this big fat lady and her dog, a Chihuahua with a rhinestone collar. I figured maybe the dog was a seeing-eye Chihuahua, because none of the guards said a word about it.

We started going up, inside the Arch. I'd never been in an elevator that went in a curve, and my stomach wasn't too happy about it.

"No parents?" the fat lady asked us.

She had beady eyes; pointy, coffee-stained teeth; a floppy denim hat, and a denim dress that bulged so much, she looked like a blue-jean blimp.

"They're below," Annabeth told her. "Scared of heights."

"Oh, the poor darlings."

The Chihuahua growled. The woman said, "Now, now, sonny. Behave." The dog had beady eyes like its owner, intelligent and vicious.

I said, "Sonny. Is that his name?"

"No," the lady told me.

She smiled, as if that cleared everything up.

At the top of the Arch, rows of tiny windows looked out over the city on one side and the river on the other. The view was okay, but if there's anything I like less than a confined space, it's a confined space six hundred feet in the air. I was ready to go pretty quick.

Annabeth kept talking about structural supports, and how she would've made the windows bigger, and designed a see-through floor. She probably could've stayed up there for hours, but luckily for me the park ranger announced that the observation deck would be closing in a few minutes.

I steered Grover and Annabeth toward the exit, loaded them into the elevator, and I was about to get in myself when I realized there were already two other tourists inside. No room for me. Magnus appeared at my elbow.

The park ranger said, "Next car, guys ."

"We'll get out," Annabeth said. "We'll wait with you."

But that was going to mess everybody up and take even more time, so I said, "Naw, it's okay. We'll see you guys at the bottom."

Magnus smiled, "Yeah Annie we'll be fine."

Grover and Annabeth both looked nervous, but they let the elevator door slide shut. Their car disappeared down the ramp.

Now the only people left on the observation deck were Magnus and I, a little boy with his parents, the park ranger, and the fat lady with her Chihuahua.

I smiled uneasily at the fat lady. She smiled back, her forked tongue flickering between her teeth.

Wait a minute.

Forked tongue?

Before I could decide if I'd really seen that, her Chihuahua jumped down and started yapping at me.

"Now, now, sonny," the lady said. "Does this look like a good time? We have all these nice people here."

"Doggie!" said the little boy. "Look, a doggie!"

His parents pulled him back.

The Chihuahua bared his teeth at me, foam dripping from his black lips.

"Well, son," the fat lady sighed. "If you insist."

Magnus looked apprehensive. "Um, did you just call that Chihuahua your son?"

"Chimera, dear," the fat lady corrected. "Not a Chihuahua. It's an easy mistake to make."

She rolled up her denim sleeves, revealing that the skin of her arms was scaly and green. When she smiled, I saw that her teeth were fangs. The pupils of her eyes were sideways slits, like a reptile's.

The Chihuahua barked louder, and with each bark, it grew. First to the size of a Doberman, then to a lion. The bark became a roar.

The little boy screamed. His parents pulled him back toward the exit, straight into the park ranger, who stood, paralyzed, gaping at the monster.

The Chimera was now so tall its back rubbed against the roof. It had the head of a lion with a blood-caked mane, the body and hooves of a giant goat, and a serpent for a tail, a ten-foot-long diamondback growing right out of its shaggy behind. The rhinestone dog collar still hung around its neck, and the plate-sized dog tag was now easy to read: CHIMERA—RABID, FIRE-BREATHING, POISONOUS—IF FOUND, PLEASE CALL TARTARUS—EXT. 954.

I realized I hadn't even uncapped my sword. My hands were numb. I was ten feet away from the Chimera's bloody maw, and I knew that as soon as I moved, the creature would lunge.

The snake lady made a hissing noise that might've been laughter. "Be honored, Percy Jackson. Lord Zeus rarely allows me to test a hero with one of my brood. For I am the Mother of Monsters, the terrible Echidna!"

I stared at her. All I could think to say was: "Isn't that a kind of anteater?"

She howled, her reptilian face turning brown and green with rage. "I hate it when people say that! I hate Australia! Naming that ridiculous animal after me. For that, Percy Jackson, my son shall destroy you!"

The Chimera charged, its lion teeth gnashing. I managed to leap aside and dodge the bite.

I ended up next to the family and the park ranger, who were all screaming now, trying to pry open the emergency exit doors.

I couldn't let them get hurt. I uncapped my sword, but before I could do anything Magnus was sprinting for the far side of the deck yelling.

"Hey, Chihuahua!" The Chimera turned faster than I would've thought possible.

I got up and tried to creep behind the Chimera.

Before I could swing my sword, it opened its mouth, emitting a stench like the world's largest barbecue pit, and shot a column of flame straight at Magnus.

He dove through the explosion. The carpet burst into flames; the heat was so intense, it nearly seared off my eyebrows.

Where he had been standing a moment before was a ragged hole in the side of the Arch, with melted metal steaming around the edges.

Great, I thought. We just blowtorched a national monument.

Riptide was now a shining bronze blade in my hands, and as the Chimera turned, I slashed at its neck.

Magnus ran at it from the other side, getting ready to stab with his dagger.

That was his fatal mistake. My blade sparked harmlessly off the dog collar an as I staggered back, trying to regain my balance, I watched in horror as the serpent tail whipped around and sank its fangs into Magnus's calf.

His leg buckled and he screamed in pain. Gritting my teeth, I stabbed Riptide at the Chimera's mouth but it sparked harmlessly of the teeth and the impact knocked my sword out of my hand, sending it spinning into the river.

I knew we had lost. I was weaponless and Magnus was struggling to stand. I remembered Chiron saying that Anaklusmos would always return to me, but there was no pen in my pocket. Maybe it had fallen too far away. Maybe it only returned when it was in pen form. I didn't know, and I wasn't going to live long enough to figure it out.

I backed into the hole in the wall. The Chimera advanced, growling, smoke curling from its lips. The snake lady, Echidna, cackled. "They don't make heroes like they used to, eh, son?"

The monster growled. It seemed in no hurry to finish me off now that I was beaten.

I glanced at the park ranger and the family. The little boy was hiding behind his father's legs. I had to protect these people. But I had no sword and Magnus had fiery poison racing through his body. We were facing a massive, fire-breathing monster and its mother. And I was scared.

There was no place else to go, so I stepped to the edge of the hole. Far, far below, the river glittered.

If I died, would the monsters go away? Would they leave the humans alone? What about Magnus though? He was dragging himself over to me, with his dagger raised but I doubted he would actually have the energy to stab anything.

"If you are the son of Poseidon," Echidna hissed, "you would not fear water. Jump, Percy Jackson. Show me that water will not harm you. Jump and retrieve your sword. Prove your bloodline."

Yeah, right, I thought. I'd read somewhere that jumping into water from a couple of stories up was like jumping onto solid asphalt. From here, I'd splatter on impact.

The Chimera's mouth glowed red, heating up for another blast.

"You have no faith," Echidna told me. "You do not trust the gods. I cannot blame you, little coward. Better you both die now. The gods are faithless. The poison is in your friends heart."

She was right: Magnus was dying. I could see the panicked look in his eyes as his chest hitched, struggling to breathe. Nobody could save us, not even the gods.

I backed up and looked down at the water. I remembered the warm glow of my father's smile when I was a baby. He must have seen me. He must have visited me when I was in my cradle.

I remembered the swirling green trident that had appeared above my head the night of capture the flag, when Poseidon had claimed me as his son.

But this wasn't the sea. This was the Mississippi, dead center of the USA. There was no Sea God here.

"Die, faithless one," Echidna rasped, and the Chimera sent a column of flame toward my face.

"Father, help us," I prayed. I grabbed Magnus's arm and turned and jumped. Dragging him over the edge. Our clothes on fire, blood rushing through my ears and poison coursing through his veins, w plummeted toward the river.
