The Son of Neptune

over the harpy?’

‘Not an option.’

Phineas smiled slowly. ‘So you are starting to understand her worth. Once I have my sight, I’ll capture her myself, you know. Whoever controls that harpy … well, I was a king once. This gamble could make me a king again.’

‘You’re getting ahead of yourself,’ Percy said. ‘Do we have a deal?’

Phineas tapped his nose thoughtfully. ‘I can’t foresee the outcome. Annoying how that works. A completely unexpected gamble … it makes the future cloudy. But I can tell you this, Percy Jackson – a bit of free advice. If you survive today, you’re not going to like your future. A big sacrifice is coming, and you won’t have the courage to make it. That will cost you dearly. It will cost the world dearly. It might be easier if you just choose the poison.’

Percy’s mouth tasted like Iris’s sour green tea. He wanted to think the old man was just psyching him out, but something told him the prediction was true. He remembered Juno’s warning when he’d chosen to go to Camp Jupiter: You will feel pain, misery and loss beyond anything you’ve ever known. But you might have a chance to save your old friends and family.

In the trees around the parking lot, the harpies gathered to watch as if they sensed what was at stake. Frank and Hazel studied Percy’s face with concern. He’d assured them the odds weren’t as bad as fifty-fifty. He did have a plan. Of course, the plan could backfire. His chance of survival might be a hundred per cent – or zero. He hadn’t mentioned that.

‘Do we have a deal?’ he asked again.

Phineas grinned. ‘I swear on the River Styx to abide by the terms, just as you have described them. Frank Zhang, you’re the descendant of an Argonaut. I trust your word. If I win, do you and your friend Hazel swear to leave me in peace, and not seek revenge?’

Frank’s hands were clenched so tight Percy thought he might break his gold spear, but he managed to grumble, ‘I swear it on the River Styx.’

‘I also swear,’ Hazel said.

‘Swear,’ Ella muttered. ‘“Swear not by the moon, the inconstant moon.”’

Phineas laughed. ‘In that case, find me something to write with. Let’s get started.’

Frank borrowed a napkin and a pen from a food truck vendor. Phineas scribbled something on the napkin and put it in his bathrobe pocket. ‘I swear this is the location of Alcyoneus’s lair. Not that you’ll live long enough to read it.’

Percy drew his sword and swept all the food off the picnic table. Phineas sat on one side. Percy sat on the other.

Phineas held out his hands. ‘Let me feel the vials.’

Percy gazed at the hills in the distance. He imagined the shadowy face of a sleeping woman. He sent his thoughts into the ground beneath him and hoped the goddess was listening.

Okay, Gaia, he said. I’m calling your bluff. You say I’m a valuable pawn. You say you’ve got plans for me, and you’re going to spare me until I make it north. Who’s more valuable to you – me, or this old man? Because one of us is about to die.

Phineas curled his fingers in a grasping motion. ‘Losing your nerve, Percy Jackson? Let me have them.’

Percy passed him the vials.

The old man compared their weight. He ran his fingers along the ceramic surfaces. Then he set them both on the table and rested one hand lightly on each. A tremor passed through the ground – a mild earthquake, just strong enough to make Percy’s teeth chatter. Ella cawed nervously.

The vial on the left seemed to shake slightly more than the one on the right.

Phineas grinned wickedly. He closed his fingers around the left-hand vial. ‘You were a fool, Percy Jackson. I choose this one. Now we drink.’

Percy took the vial on the right. His teeth were chattering.

The old man raised his vial. ‘A toast to the sons of Neptune.’

They both uncorked their vials and drank.

Immediately, Percy doubled over, his throat burning. His mouth tasted like gasoline.

‘Oh, gods,’ Hazel said behind him.

‘Nope!’ Ella said. ‘Nope, nope, nope.’

Percy’s vision blurred. He could see Phineas grinning in triumph, sitting up straighter, blinking his eyes in anticipation.

‘Yes!’ he cried. ‘Any moment now, my sight will return!’

Percy had chosen wrong. He’d been stupid to take such a risk. He felt like broken glass was working its way through his stomach, into his intestines.

‘Percy!’ Frank gripped his shoulders. ‘Percy, you can’t die!’

He gasped for breath … and suddenly his vision cleared.

At the same moment, Phineas hunched over like he’d been punched.

‘You – you can’t!’ the old man wailed. ‘Gaia, you – you -’

He staggered to his feet and stumbled away from the table, clutching his stomach. ‘I’m too valuable!’

Steam came out of his mouth. A sickly yellow vapour rose from his ears, his beard, his blind eyes.

‘Unfair!’ he screamed. ‘You tricked me!’

He tried to claw the piece of paper out of his robe pocket, but his hands crumbled, his fingers turning to sand.

Percy rose unsteadily. He didn’t feel cured of anything in particular. His memory hadn’t magically returned. But the pain had stopped.

‘No one tricked you,’ Percy said. ‘You made your choice freely, and I hold you to your oath.’

The blind king wailed in agony. He turned in a circle, steaming and slowly disintegrating until there was nothing left but an old, stained bathrobe and a pair of bunny slippers.

‘Those,’ Frank said, ‘are the most disgusting spoils of war ever.’

A woman’s voice spoke in Percy’s mind. A gamble, Percy Jackson. It was a sleepy whisper, with just a hint of grudging admiration. You forced me to choose, and you are more important to my plans than the old seer. But do not press your luck. When your death comes, I promise it will be much more painful than gorgon’s blood.

Hazel prodded the robe with her sword. There was nothing underneath – no sign that Phineas was trying to re- form. She looked at Percy in awe. ‘That was either the bravest thing I’ve ever seen, or the stupidest.’

Frank shook his head in disbelief. ‘Percy, how did you know? You were so confident he’d choose the poison.’

‘Gaia,’ Percy said. ‘She wants me to make it to Alaska. She thinks … I’m not sure. She thinks she can use me as part of her plan. She influenced Phineas to choose the wrong vial.’

Frank stared in horror at the remains of the old man. ‘Gaia would kill her own servant rather than you? That’s what you were betting on?’

‘Plans,’ Ella muttered. ‘Plans and plots. The lady in the ground. Big plans for Percy. Macrobiotic jerky for Ella.’

Percy handed her the whole bag of jerky and she squeaked with joy. ‘Nope, nope, nope,’ she muttered, half- singing. ‘Phineas, nope. Food and words for Ella, yep.’

Percy crouched over the bathrobe and pulled the old man’s note out of the pocket. It read: HUBBARD GLACIER.

All that risk for two words. He handed the note to Hazel.

‘I know where that is,’ she said. ‘It’s pretty famous. But we’ve got a long, long way to go.’

In the trees around the parking lot, the other harpies finally overcame their shock. They squawked with excitement and flew at the nearest food trucks, diving through the service windows and raiding the kitchens. Cooks shouted in many languages. Trucks shook back and forth. Feathers and food boxes flew everywhere.

‘We’d better get back to the boat,’ Percy said. ‘We’re running out of time.’
