‘What’s this “other way”?’ I asked Annabeth. ‘The thing Clarisse mentioned?’
She picked up a stone and skipped it across the lake. ‘Something Clarisse scouted out. I helped her a little this spring. But it would be dangerous. Especially for Grover.’
‘Goat boy scares me,’ Tyson murmured.
I stared at him. Tyson had faced down fire-breathing bulls and sea monsters and cannibal giants. ‘Why would you be scared of Grover?’
‘Hooves and horns,’ Tyson muttered nervously. ‘And goat fur makes my nose itchy.’
And that pretty much ended our Grover conversation.
Before dinner, Tyson and I went down to the sword arena. Quintus was glad to have company. He still wouldn’t tell me what was in the wooden crates, but he did teach me a few sword moves. The guy was good. He fought the way some people play chess – like he was putting all the moves together and you couldn’t see the pattern until he made the last stroke and won with a sword at your throat.
‘Good try,’ he told me. ‘But your guard is too low.’
He lunged and I blocked.
‘Have you always been a swordsman?’ I asked.
He parried my overhead cut. ‘I’ve been many things.’
He jabbed and I sidestepped. His shoulder strap slipped down, and I saw that mark on his shoulder – the purple blotch. But it wasn’t a random mark. It had a definite shape – a bird with folded wings, like a quail or something.
‘What’s that on your neck?’ I asked, which was probably a rude question, but you can blame my ADHD. I tend to just blurt things out.
Quintus lost his rhythm. I hit his sword hilt and knocked the blade out of his hand.
He rubbed his fingers. Then he shifted his armour to hide the mark. It wasn’t a tattoo, I realized. It was an old burn… like he’d been branded.
‘A reminder.’ He picked up his sword and forced a smile. ‘Now, shall we go again?’
He pressed me hard, not giving me time for any more questions.
While he and I fought, Tyson played with Mrs O’Leary, whom he called the ‘little doggie’. They had a great time wrestling for the bronze shield and playing Get the Greek. By sunset, Quintus hadn’t even broken a sweat, which seemed kind of strange, but Tyson and I were hot and sticky, so we hit the showers and got ready for dinner.
I was feeling good. It was almost like a normal day at camp. Then dinner came, and all the campers lined up by their cabins and marched into the dining pavilion. Most of them ignored the sealed fissure in the marble floor at the entrance – a three-metre-long jagged scar that hadn’t been there last summer – but I was careful to step over it.
‘Big crack,’ Tyson said when we were at our table. ‘Earthquake, maybe?’
‘No,’ I said. ‘Not an earthquake.’
I wasn’t sure I should tell him. It was a secret only Annabeth and Grover and I knew. But looking in Tyson’s big eye, I knew I couldn’t hide anything from him.
‘Nico di Angelo,’ I said, lowering my voice. ‘He’s this half-blood kid we brought to camp last winter. He, uh… he asked me to guard his sister on a quest, and I failed. She died. Now he blames me.’
Tyson frowned. ‘So he put a crack in the floor?’
‘These skeletons attacked us,’ I said. ‘Nico told them to go away, and the ground just opened up and swallowed them. Nico…’ I looked around to make sure no one was listening. ‘Nico is a son of Hades.’
Tyson nodded thoughtfully. ‘The god of dead people.’
‘Yeah.’
‘So the Nico boy is gone now?’
‘I – I guess. I tried to search for him this spring. So did Annabeth. But we didn’t have any luck. This is secret, Tyson. Okay? If anyone found out he is a son of Hades, he would be in danger. You can’t even tell Chiron.’
‘The bad prophecy,’ Tyson said. ‘Titans might use him if they knew.’
I stared at him. Sometimes it was easy to forget that, as big and childlike as he was, Tyson was pretty smart. He knew that the next child of the Big Three gods – Zeus, Poseidon or Hades – who turned sixteen was prophesied to either save or destroy Mount Olympus. Most people assumed that meant me, but if I died before I turned sixteen, the prophecy could just as easily apply to Nico.
‘Exactly,’ I said. ‘So –’
‘Mouth sealed,’ Tyson promised. ‘Like the crack in the ground.’
∗ ∗ ∗
I had trouble falling asleep that night. I lay in bed listening to the waves on the beach, and the owls and monsters in the woods. I was afraid once I drifted off I’d have nightmares.
See, for half-bloods, dreams are hardly ever just dreams. We get messages. We see things that are happening to our friends or enemies. Sometimes we even glimpse the past or the future. And at camp, my dreams were always more frequent and vivid.
So I was still awake around midnight, staring at the bunk-bed mattress above me, when I realized there was a strange light in the room. The saltwater fountain was glowing.
I threw off the covers and walked cautiously towards it. Steam rose from the hot salt water. Rainbow colours shimmered through it, though there was no light in the room except for the moon outside. Then a pleasant female voice spoke from the steam: Please deposit one drachma.
I looked over at Tyson, but he was still snoring. He sleeps about as heavily as a tranquillized elephant.
I didn’t know what to think. I’d never had a collect Iris-message before. One golden drachma gleamed at the bottom of the fountain. I scooped it up and tossed it through the Mist. The coin vanished.
‘O, Iris, Goddess of the Rainbow,’ I whispered. ‘Show me… uh, whatever you need to show me.’
The Mist shimmered. I saw the dark shore of a river. Wisps of fog drifted across black water. The beach was strewn with jagged volcanic rock. A young boy squatted at the riverbank, tending a campfire. The flames burned an unnatural blue colour. Then I saw the boy’s face. It was Nico di Angelo. He was throwing pieces of paper into the fire – Mythomagic trading cards, part of the game he’d been obsessed with last winter.
Nico was only ten, or maybe eleven by now, but he looked older. His hair had grown longer. It was shaggy and almost touched his shoulders. His eyes were dark. His olive skin had turned paler. He wore ripped black jeans and a battered aviator’s jacket that was several sizes too big, unzipped over a black shirt. His face was grimy, his eyes a little wild. He looked like a kid who’d been living on the streets.
I waited for him to look at me. No doubt he’d get crazy angry, start accusing me of letting his sister die. But he didn’t seem to notice me.
I stayed quiet, not daring to move. If he hadn’t sent this Iris-message, who had?
Nico tossed another trading card into the blue flames. ‘Useless,’ he muttered. ‘I can’t believe I ever liked this stuff.’
‘A childish game, master,’ another voice agreed. It seemed to come from near the fire, but I couldn’t see who was talking.
Nico stared across the river. On the far shore was a black beach shrouded in haze. I recognized it: the Underworld. Nico was camping at the edge of the River Styx.
‘I’ve failed,’ he muttered. ‘There’s no way to get her back.’
The other voice kept silent.
Nico turned towards it doubtfully. ‘Is there? Speak.’
Something shimmered. I thought it was just firelight. Then I realized it was the form of a man – a wisp of blue smoke, a shadow. If you looked at him head-on, he wasn’t there. But if you looked out of the corner of your eye, you could make out his shape. A ghost.
‘It has never been done,’ the ghost said. ‘But there may be a way.’
‘Tell me,’ Nico commanded. His eyes shone with a fierce light.
‘An exchange,’ the ghost said. ‘A soul for a soul.’
‘I’ve offered!’
‘Not yours,’ the ghost said. ‘You cannot offer your father a soul he will eventually collect anyway. Nor will he be anxious for the death of hi
s son. I mean a soul that should have died already. Someone who has cheated death.’
Nico’s face darkened. ‘Not that again. You’re talking about murder.’
‘I’m talking about justice,’ the ghost said. ‘Vengeance.’
‘Those are not the same thing.’
The ghost laughed dryly. ‘You will learn differently as you get older.’
Nico stared at the flames. ‘Why can’t I at least summon her? I want to talk to her. She would… she would help me.’
‘I will help you,’ the ghost promised. ‘Have I not saved you many times? Did I not lead you through the maze and teach you to use your powers? Do you want revenge for your sister or not?’
I didn’t like the ghost’s tone of voice. He reminded me of a kid at my old school, a bully who used to convince other kids to do stupid things like steal lab equipment and vandalize the teachers’ cars. The bully never got into trouble himself, but he got tons of other kids suspended.
Nico turned from the fire so the ghost couldn’t see him, but I could. A tear traced its way down his face. ‘Very well. You have a plan?’
‘Oh, yes,’ the ghost said, sounding quite pleased. ‘We have many dark roads to travel. We must start –’
The image shimmered. Nico vanished. The woman’s voice from the Mist said, Please deposit one drachma for another five minutes.
There were no other coins in the fountain. I grabbed for my pockets, but I was wearing pyjamas. I lunged for the nightstand to check for spare change, but the Iris-message had already blinked out, and the room went dark again. The connection was broken.
I stood in the middle of the cabin, listening to the gurgle of the saltwater fountain and the ocean waves outside.
Nico was alive. He was trying to bring his sister back from the dead. And I had a feeling I knew whose soul he wanted to exchange – someone who had cheated death. Vengeance.
Nico di Angelo would come looking for me.
3 We Play Tag With Scorpions
The next morning there was a lot of excitement at breakfast.
Apparently around three in the morning an Aethiopian drakon had been spotted at the borders of camp. I was so exhausted I slept right through the noise. The magical boundaries had kept the monster out, but it prowled the hills, looking for weak spots in our defences, and it didn’t seem anxious to go away until Lee Fletcher from Apollo’s cabin led a couple of his siblings in pursuit. After a few dozen arrows lodged in the chinks of the drakon’s armour, it got the message and withdrew.
‘It’s still out there,’ Lee warned us during announcements. ‘Twenty arrows in its hide, and we just made it mad. The thing was ten metres long and bright green. Its eyes –’ He shuddered.
‘You did well, Lee.’ Chiron patted him on the shoulder. ‘Everyone stay alert, but stay calm. This has happened before.’
‘Aye,’ Quintus said from the head table. ‘And it will happen again. More and more frequently.’
The campers murmured among themselves.
Everyone knew the rumours: Luke and his army of monsters were planning an invasion of the camp. Most of us expected it to happen this summer, but no one knew how or when. It didn’t help that our attendance was down. We only had about eighty campers. Three years ago, when I’d started, there had been more than a hundred. Some had died. Some had joined Luke. Some had just disappeared.
‘This is a good reason for new war games,’ Quintus continued, a glint in his eyes. ‘We’ll see how you all do with that tonight.’
‘Yes …’ Chiron said. ‘Well, enough announcements. Let us bless this meal and eat.’ He raised his goblet. ‘To the gods!’
We all raised our glasses and repeated the blessing.
Tyson and I took our plates to the bronze brazier and scraped a portion of our food into the flames. I hoped the gods liked raisin toast and Cheerios.
‘Poseidon,’ I said. Then I whispered, ‘Help me with Nico, and Luke, and Grover’s problem …’
There was so much to worry about I could’ve stood there all morning, but I headed back to my table.
Once everyone was eating, Chiron and Grover came over to visit. Grover was bleary-eyed. His shirt was inside out. He slid his plate onto the table and slumped next to me.
Tyson shifted uncomfortably. ‘I will go … um … polish my fish ponies.’
He lumbered off, leaving his breakfast half eaten.
Chiron tried for a smile. He probably wanted to look reassuring, but in centaur form he towered over me, casting a shadow across the table. ‘Well, Percy, how did you sleep?’
‘Uh, fine.’ I wondered why he asked that. Was it possible he knew something about the weird Iris-message I’d got?
‘I brought Grover over,’ Chiron said, ‘because I thought you two might want to, ah, discuss matters. Now, if you’ll excuse me, I have some Iris-messages to send. I’ll see you later in the day.’ He gave Grover a meaningful look, then trotted out of the pavilion.
‘What’s he talking about?’ I asked Grover.
Grover chewed his eggs. I could tell he was distracted, because he bit off the tines of his fork and chewed those down, too. ‘He wants you to convince me,’ he mumbled.
Somebody else slid next to me on the bencn: Annabeth.
‘I’ll tell you what it’s about,’ she said. ‘The Labyrinth.’
It was hard to concentrate on what she was saying, because everybody in the dining pavilion was stealing glances at us and whispering. And Annabeth was right next to me. I mean right next to me.
‘You’re not supposed to be here,’ I said.
‘We need to talk,’ she insisted.
‘But the rules …’
She knew as well as I did that campers weren’t allowed to switch tables. Satyrs were different. They weren’t really demigods. But the half-bloods had to sit with their cabins. I wasn’t even sure what the punishment was for switching tables. I’d never seen it happen. If Mr D had been here, he probably would’ve strangled Annabeth with magical grapevines or something, but Mr D wasn’t here. Chiron had already left the pavilion. Quintus looked over and raised an eyebrow, but he didn’t say anything.
‘Look,’ Annabeth said. ‘Grover is in trouble. There’s only one way we can figure out to help him. It’s the Labyrinth. That’s what Clarisse and I have been investigating.’
I shifted my weight, trying to think clearly. ‘You mean the maze where they kept the Minotaur, back in the old days?’
‘Exactly,’ Annabeth said.
‘So … it’s not under the king’s palace in Crete any more,’ I guessed. ‘The Labyrinth is under some building in America.’
See? It only took me a few years to work things out. I knew that important places moved around with Western Civilization, like Mount Olympus being over the Empire State Building, and the Underworld entrance being in Los Angeles. I was feeling pretty proud of myself.
Annabeth rolled her eyes. ‘Under a building? Please, Percy. The Labyrinth is huge. It wouldn’t fit under a single city, much less a single building.’
I thought about my dream of Nico at the River Styx. ‘So … is the Labyrinth part of the Underworld?’
‘No.’ Annabeth frowned. ‘Well, there may be passages from the Labyrinth down into the Underworld. I’m not sure. But the Underworld is way, way down. The Labyrinth is right under the surface of the mortal world, kind of like a second skin. It’s been growing for thousands of years, lacing its way under Western cities, connecting everything together underground. You can get anywhere through the Labyrinth.’
‘If you don’t get lost,’ Grover muttered. ‘And die a horrible death.’
‘Grover, there has to be a way,’ Annabeth said. I got the feeling they’d had this conversation before. ‘Clarisse lived.’
‘Barely!’ Grover said. ‘And the other guy –’
‘He was driven insane. He didn’t die.’
‘Oh, joy.’ Grover’s lower lip quivered. ‘That makes me feel much better.’
‘Whoa,’ I
said. ‘Back up. What’s this about Clarisse and a crazy guy?’
Annabeth glanced over towards the Ares table. Clarisse was watching us like she knew what we were talking about, but then she fixed her eyes on her breakfast plate.
‘Last year,’ Annabeth said, lowering her voice, ‘Clarisse went on a mission for Chiron.’
‘I remember,’ I said. ‘It was secret.’
Annabeth nodded. Despite how serious she was acting, I was happy she wasn’t mad at me any more. And I kind of liked the fact that she’d broken the rules to come sit next to me.
‘It was secret,’ Annabeth agreed, ‘because she found Chris Rodriguez.’
‘The guy from the Hermes cabin?’ I remembered him from two years ago. We’d eavesdropped on Chris Rodriguez aboard Luke’s ship, the Princess Andromeda. Chris was one of the half-bloods who’d abandoned camp and joined the Titan army.
‘Yeah,’ Annabeth said. ‘Last summer he just appeared in Phoenix, Arizona, near Clarisse’s mom’s house.’
‘What do you mean, he just appeared?’
‘He was wandering around the desert, in fifty degrees, in full Greek armour, babbling about string.’
‘String,’ I said.
‘He’d been driven completely insane. Clarisse brought him back to her mom’s house so the mortals wouldn’t institutionalize him. She tried to nurse him back to health. Chiron came out and interviewed him, but it wasn’t much good. The only thing they got out of him: Luke’s men have been exploring the Labyrinth.’
I shivered, though I wasn’t sure exactly why. Poor Chris … He hadn’t been that bad a guy. What could’ve driven him mad? I looked at Grover, who was chewing up the rest of his fork.
‘Okay,’ I asked. ‘Why were they exploring the Labyrinth?’
‘We weren’t sure,’ Annabeth said. ‘That’s why Clarisse went on a scouting expedition. Chiron kept things hushed up because he didn’t want anyone panicking. He got me involved because … well, the Labyrinth has always been one of my favourite subjects. The architecture involved –’ Her expression turned a little dreamy. ‘The builder, Daedalus, was a genius. But the point is, the Labyrinth has entrances everywhere. If Luke could figure out how to navigate it, he could move his army around with incredible speed.’
