The jogger didn’t seem to notice. He checked his LCD screen and cursed. ‘I’ve got to take this. Just a sec…’ Then into the phone, ‘Hello?’

  He listened. The mini-snakes writhed up and down the antenna right next to his ear.

  ‘Yeah,’ the jogger said. ‘Listen – I know, but … I don’t care if he is chained to a rock with vultures pecking at his liver, if he doesn’t have a tracking number, we can’t locate his package … A gift to humankind, great … You know how many of those we deliver – Oh, never mind. Listen, just refer him to Eris in customer service. I gotta go.’

  He hung up. ‘Sorry. The overnight express business is just booming. Now, as I was saying –’

  ‘You have snakes on your phone.’

  ‘What? Oh, they don’t bite. Say hello, George and Martha.’

  Hello, George and Martha, a raspy male voice said inside my head.

  Don’t be sarcastic, said a female voice.

  Why not? George demanded. I do all the real work.

  ‘Oh, let’s not go into that again!’ The jogger slipped his phone back into his pocket. ‘Now, where were we … Ah, yes. Peace and quiet.’

  He crossed his ankles and stared up at the stars. ‘Been a long time since I’ve got to relax. Ever since the telegraph – rush, rush, rush. Do you have a favourite constellation, Percy?’

  I was still kind of wondering about the little green snakes he’d shoved into his jogging shorts, but I said, ‘Uh, I like Heracles.’

  ‘Why?’

  ‘Well … because he had rotten luck. Even worse than mine. It makes me feel better.’

  The jogger chuckled. ‘Not because he was strong and famous and all that?’

  ‘No.’

  ‘You’re an interesting young man. And so, what now?’

  I knew immediately what he was asking. What did I intend to do about the Fleece?

  Before I could answer, Martha the snake’s muffled voice came from his pocket, I have Demeter on line two.

  ‘Not now,’ the jogger said. ‘Tell her to leave a message.’

  She’s not going to like that. The last time you put her off, all the flowers in the floral delivery division wilted.

  ‘Just tell her I’m in a meeting!’ The jogger rolled his eyes. ‘Sorry again, Percy. You were saying…’

  ‘Um … who are you, exactly?’

  ‘Haven’t you guessed by now, a smart boy like you?’

  Show him! Martha pleaded. I haven’t been full-size for months.

  Don’t listen to her! George said. She just wants to show off!

  The man took out his phone again. ‘Original form, please.’

  The phone glowed a brilliant blue. It stretched into a metre-long wooden staff with dove wings sprouting out the top. George and Martha, now full-sized green snakes, coiled together around the middle. It was a caduceus, the symbol of Cabin Eleven.

  My throat tightened. I realized who the jogger reminded me of with his elfish features, the mischievous twinkle in his eyes….

  ‘You’re Luke’s father,’ I said. ‘Hermes.’

  The god pursed his lips. He stuck his caduceus in the sand like an umbrella pole. ‘ “Luke’s father.” Normally, that’s not the first way people introduce me. God of thieves, yes. God of messengers and travellers, if they wish to be kind.’

  God of thieves works, George said.

  Oh, don’t mind George. Martha flicked her tongue at me. He’s just bitter because Hermes likes me best.

  He does not!

  Does too!

  ‘Behave, you two,’ Hermes warned, ‘or I’ll turn you back into a cell phone and set you on vibrate! Now, Percy, you still haven’t answered my question. What do you intend to do about the quest?’

  ‘I – I don’t have permission to go.’

  ‘No, indeed. Will that stop you?’

  ‘I want to go. I have to save Grover.’

  Hermes smiled. ‘I knew a boy once … oh, younger than you by far. A mere baby, really.’

  Here we go again, George said. Always talking about himself.

  Quiet! Martha snapped. Do you want to get set on vibrate?

  Hermes ignored them. ‘One night, when this boy’s mother wasn’t watching, he sneaked out of their cave and stole some cattle that belonged to Apollo.’

  ‘Did he get blasted to tiny pieces?’ I asked.

  ‘Hmm … no. Actually, everything turned out quite well. To make up for his theft, the boy gave Apollo an instrument he’d invented – a lyre. Apollo was so enchanted with the music that he forgot all about being angry.’

  ‘So what’s the moral?’

  ‘The moral?’ Hermes asked. ‘Goodness, you act like it’s a fable. It’s a true story. Does truth have a moral?’

  ‘Um…’

  ‘How about this: stealing is not always bad?’

  ‘I don’t think my mom would like that moral.’

  Rats are delicious, suggested George.

  What does that have to do with the story? Martha demanded.

  Nothing, George said. But I’m hungry.

  ‘I’ve got it,’ Hermes said. ‘Young people don’t always do what they’re told, but if they can pull it off and do something wonderful, sometimes they escape punishment. How’s that?’

  ‘You’re saying I should go anyway,’ I said, ‘even without permission.’

  Hermes’s eyes twinkled. ‘Martha, may I have the first package, please?’

  Martha opened her mouth … and kept opening it until it was as wide as my arm. She belched out a stainless steel canister – an old-fashioned lunch box flask with a black plastic top. The sides of the flask were enamelled with red and yellow Ancient Greek scenes – a hero killing a lion; a hero lifting up Cerberus, the three-headed dog.

  ‘That’s Heracles,’ I said. ‘But how –’

  ‘Never question a gift,’ Hermes chided. ‘This is a collector’s item from Heracles Busts Heads. The first season.’

  ‘Heracles Busts Heads?’

  ‘Great show.’ Hermes sighed. ‘Back before Hephaestus-TV was all reality programming. Of course, the Flask would be worth much more if I had the whole lunch box –’

  Or if it hadn’t been in Martha’s mouth, George added.

  I’ll get you for that. Martha began chasing him around the caduceus.

  ‘Wait a minute,’ I said. ‘This is a gift?’

  ‘One of two,’ Hermes said. ‘Go on, pick it up.’

  I almost dropped it because it was freezing cold on one side and burning hot on the other. The weird thing was, when I turned the Flask, the side facing the ocean – north – was always the cold side…

  ‘It’s a compass!’ I said.

  Hermes looked surprised. ‘Very clever. I never thought of that. But its intended use is a bit more dramatic. Uncap it, and you will release the winds from the four corners of the earth to speed you on your way. Not now! And please, when the time comes, only unscrew the lid a tiny bit. The winds are a bit like me – always restless. Should all four escape at once … ah, but I’m sure you’ll be careful. And now my second gift. George?’

  She’s touching me, George complained as he and Martha slithered around the pole.

  ‘She’s always touching you,’ Hermes said. ‘You’re intertwined. And if you don’t stop that, you’ll get knotted again!’

  The snakes stopped wrestling.

  George unhinged his jaw and coughed up a little plastic bottle filled with chewable vitamins.

  ‘You’re kidding,’ I said. ‘Are those Minotaur-shaped?’

  Hermes picked up the bottle and rattled it. ‘The lemon ones, yes. The grape ones are Furies, I think. Or are they hydras? At any rate, these are potent. Don’t take one unless you really, really need it.’

  ‘How will I know if I really, really need it?’

  ‘You’ll know, believe me. Nine essential vitamins, minerals, amino acids … oh, everything you need to feel yourself again.’

  He tossed me the bottle.

  ‘Um, than
ks,’ I said. ‘But Lord Hermes, why are you helping me?’

  He gave me a melancholy smile. ‘Perhaps because I hope that you can save many people on this quest, Percy. Not just your friend Grover.’

  I stared at him. ‘You don’t mean … Luke?’

  Hermes didn’t answer.

  ‘Look,’ I said. ‘Lord Hermes, I mean, thanks and everything, but you might as well take back your gifts. Luke can’t be saved. Even if I could find him … he told me he wanted to tear down Olympus stone by stone. He betrayed everybody he knew. He – he hates you especially.’

  Hermes gazed up at the stars. ‘My dear young cousin, if there’s one thing I’ve learned over the aeons, it’s that you can’t give up on your family, no matter how tempting they make it. It doesn’t matter if they hate you, or embarrass you, or simply don’t appreciate your genius for inventing the internet –’

  ‘You invented the internet?’

  It was my idea, Martha said.

  Rats are delicious, George said.

  ‘It was my idea!’ Hermes said. ‘I mean the internet, not the rats. But that’s not the point. Percy, do you understand what I’m saying about family?’

  ‘I – I’m not sure.’

  ‘You will some day.’ Hermes got up and brushed the sand off his legs. ‘In the meantime, I must be going.’

  You have sixty calls to return, Martha said.

  And one thousand and thirty-eight emails, George added. Not counting the offers for online discount ambrosia.

  ‘And you, Percy,’ Hermes said, ‘have a shorter deadline than you realize to complete your quest. Your friends should be coming right about … now.’

  I heard Annabeth’s voice calling my name from the sand dunes. Tyson, too, was shouting from a little bit further away.

  ‘I hope I packed well for you,’ Hermes said. ‘I do have some experience with travel.’

  He snapped his fingers and three yellow duffel bags appeared at my feet. ‘Waterproof, of course. If you ask nicely, your father should be able to help you reach the ship.’

  ‘Ship?’

  Hermes pointed. Sure enough, a big cruise ship was cutting across Long Island Sound, its white-and-gold lights glowing against the dark water.

  ‘Wait,’ I said. ‘I don’t understand any of this. I haven’t even agreed to go!’

  ‘I’d make up your mind in the next five minutes, if I were you,’ Hermes advised. ‘That’s when the harpies will come to eat you. Now, goodnight, cousin, and dare I say it? May the gods go with you.’

  He opened his hand and the caduceus flew into it.

  Good luck, Martha told me.

  Bring me back a rat, George said.

  The caduceus changed into a cell phone and Hermes slipped it into his pocket.

  He jogged off down the beach. Twenty paces away, he shimmered and vanished, leaving me alone with a flask, a bottle of chewable vitamins and five minutes to make an impossible decision.

  8 We Board the Princess Andromeda

  I was staring at the waves when Annabeth and Tyson found me.

  ‘What’s going on?’ Annabeth asked. ‘I heard you calling for help!’

  ‘Me, too!’ Tyson said. ‘Heard you yell, “Bad things are attacking!’ ”

  ‘I didn’t call you guys,’ I said. ‘I’m fine.’

  ‘But then who…’ Annabeth noticed the three yellow duffel bags, then the Flask and the bottle of vitamins I was holding. ‘What –’

  ‘Just listen,’ I said. ‘We don’t have much time.’

  I told them about my conversation with Hermes. By the time I was finished, I could hear screeching in the distance – patrol harpies picking up our scent.

  ‘Percy,’ Annabeth said, ‘we have to do the quest.’

  ‘We’ll get expelled, you know. Trust me, I’m an expert at getting expelled.’

  ‘So? If we fail, there won’t be any camp to come back to.’

  ‘Yeah, but you promised Chiron –’

  ‘I promised I’d keep you from danger. I can only do that by coming with you! Tyson can stay behind and tell them –’

  ‘I want to go,’ Tyson said.

  ‘No!’ Annabeth’s voice sounded close to panic. ‘I mean … Percy, come on. You know that’s impossible.’

  I wondered again why she had such a grudge against Cyclopes. There was something she wasn’t telling me.

  She and Tyson both looked at me, waiting for an answer. Meanwhile, the cruise ship was getting further and further away.

  The thing was, part of me didn’t want Tyson along. I’d spent the last three days in close quarters with the guy, getting teased by the other campers and embarrassed a million times a day, constantly reminded that I was related to him. I needed some space.

  Plus, I didn’t know how much help he’d be, or how I’d keep him safe. Sure, he was strong, but Tyson was a little kid in Cyclops terms, maybe seven or eight years old, mentally. I could see him freaking out and starting to cry while we were trying to sneak past a monster or something. He’d get us all killed.

  On the other hand, the sound of the harpies was getting closer…

  ‘We can’t leave him,’ I decided. ‘Tantalus will punish him for us being gone.’

  ‘Percy,’ Annabeth said, trying to keep her cool, ‘we’re going to Polyphemus’s island! Polyphemus is an S-i-k … a C-y-k…’ She stamped her foot in frustration. As smart as she was, Annabeth was dyslexic, too. We could’ve been there all night while she tried to spell Cyclops. ‘You know what I mean!’

  ‘Tyson can go,’ I insisted, ‘if he wants to.’

  Tyson clapped his hands. ‘Want to!’

  Annabeth gave me the evil eye, but I guess she could tell I wasn’t going to change my mind. Or maybe she just knew we didn’t have time to argue.

  ‘All right,’ she said. ‘How do we get to that ship?’

  ‘Hermes said my father would help.’

  ‘Well then, Seaweed Brain? What are you waiting for?’

  I’d always had a hard time calling on my father, or praying, or whatever you want to call it, but I stepped into the waves.

  ‘Um, Dad?’ I called. ‘How’s it going?’

  ‘Percy!’ Annabeth whispered. ‘We’re in a hurry!’

  ‘We need your help,’ I called a little louder. ‘We need to get to that ship, like, before we get eaten and stuff, so…’

  At first, nothing happened. Waves crashed against the shore like normal. The harpies sounded like they were right behind the sand dunes. Then, about a hundred metres out to sea, three white lines appeared on the surface. They moved fast towards the shore, like claws ripping through the ocean.

  As they neared the beach, the surf burst apart and the heads of three white stallions reared out of the waves.

  Tyson caught his breath. ‘Fish ponies!’

  He was right. As the creatures pulled themselves onto the sand, I saw that they were only horses in the front; their back halves were silvery fish bodies, with glistening scales and rainbow-tail fins.

  ‘Hippocampi!’ Annabeth said. ‘They’re beautiful.’

  The nearest one whinnied in appreciation and nuzzled Annabeth.

  ‘We’ll admire them later,’ I said. ‘Come on!’

  ‘There!’ a voice screeched behind us. ‘Bad children out of cabins! Snack time for lucky harpies!’

  Five of them were fluttering over the top of the dunes – plump little hags with pinched faces and talons and feathery wings too small for their bodies. They reminded me of miniature cafeteria ladies who’d been crossbred with dodo birds. They weren’t very fast, thank the gods, but they were vicious if they caught you.

  ‘Tyson!’ I said. ‘Grab a duffel bag!’

  He was still staring at the hippocampi with his mouth hanging open.

  ‘Tyson!’

  ‘Uh?’

  ‘Come on!’

  With Annabeth’s help I got him moving. We gathered the bags and mounted our steeds. Poseidon must’ve known Tyson was one of the passengers, be
cause one hippocampus was much larger than the other two – just right for carrying a Cyclops.

  ‘Giddy-up!’ I said. My hippocampus turned and plunged into the waves. Annabeth’s and Tyson’s followed right behind.

  The harpies cursed at us, wailing for their snacks to come back, but the hippocampi raced over the water at the speed of jet skis. The harpies fell behind, and soon the shore of Camp Half-Blood was nothing but a dark smudge. I wondered if I’d ever see the place again. But right then I had other problems.

  The cruise ship was now looming in front of us – our ride towards Florida and the Sea of Monsters.

  * * *

  Riding the hippocampus was even easier than riding a pegasus. We zipped along with the wind in our faces, speeding through the waves so smoothly and steadily I hardly needed to hold on at all.

  As we got closer to the cruise ship, I realized just how huge it was. I felt as though I were looking up at a building in Manhattan. The white hull was at least ten storeys tall, topped with another dozen levels of decks with brightly lit balconies and portholes. The ship’s name was painted just above the bow line in black letters, lit with a spotlight. It took me a few seconds to decipher it:

  PRINCESS ANDROMEDA

  Attached to the bow was a huge masthead – a three-storey-tall woman wearing a white Greek chiton, sculpted to look as if she were chained to the front of the ship. She was young and beautiful, with flowing black hair, but her expression was one of absolute terror. Why anybody would want a screaming princess on the front of their vacation ship, I had no idea.

  I remembered the myth about Andromeda and how she had been chained to a rock by her own parents as a sacrifice to a sea monster. Maybe she’d got too many Fs on her report card or something. Anyway, my namesake, Perseus, had saved her just in time and turned the sea monster to stone using the head of Medusa.

  That Perseus always won. That’s why my mom had named me after him, even though he was a son of Zeus and I was a son of Poseidon. The original Perseus was one of the only heroes in the Greek myths who got a happy ending. The others died – betrayed, mauled, mutilated, poisoned, or cursed by the gods. My mom hoped I would inherit Perseus’s luck. Judging by how my life was going so far, I wasn’t really optimistic.
