The Son of Neptune

idiot.’

Hazel’s sword came down on the giant’s neck. Alcyoneus dissolved into a pile of very expensive rocks.

For a while Hazel and Frank stood together, watching the remains of the giant melt into the ice. Frank picked up his rope.

‘An elephant?’ Hazel asked.

Frank scratched his neck. ‘Yeah. It seemed like a good idea.’

He couldn’t read her expression. He was afraid he’d finally done something so weird that she’d never want to be around him again. Frank Zhang: lumbering klutz, child of Mars, part-time pachyderm.

Then she kissed him – a real kiss on the lips, much better than the kind of kiss she’d given Percy on the aeroplane.

‘You are amazing,’ she said. ‘And you make a very handsome elephant.’

Frank felt so flustered that he thought his boots might melt through the ice. Before he could say anything, a voice echoed across the valley:

You haven’t won.

Frank looked up. Shadows were shifting across the nearest mountain, forming the face of a sleeping woman.

You will never reach home in time, taunted the voice of Gaia. Even now, Thanatos is attending the death of Camp Jupiter, the final destruction of your Roman friends.

The mountain rumbled as if the whole earth were laughing. The shadows disappeared.

Hazel and Frank looked at each other. Neither said a word. They climbed onto Arion and sped back towards Glacier Bay.

XLVIII Frank

PERCY WAS WAITING FOR THEM. He looked mad.

He stood at the edge of the glacier, leaning on the staff with the golden eagle, gazing down at the wreckage he’d caused: several hundred acres of newly open water dotted with icebergs and flotsam from the ruined camp.

The only remains on the glacier were the main gates, which listed sideways, and a tattered blue banner lying over a pile of snow-bricks.

When they ran up to him, Percy said, ‘Hey,’ like they were just meeting for lunch or something.

‘You’re alive!’ Frank marvelled.

Percy frowned. ‘The fall? That was nothing. I fell twice that far from the St Louis Arch.’

‘You did what?’ Hazel asked.

‘Never mind. The important thing was I didn’t drown.’

‘So the prophecy was incomplete!’ Hazel grinned. ‘It probably said something like: The son of Neptune will drown a whole bunch of ghosts.’

Percy shrugged. He was still looking at Frank like he was miffed. ‘I got a bone to pick with you, Zhang. You can turn into an eagle? And a bear?’

‘And an elephant,’ Hazel said proudly.

‘An elephant.’ Percy shook his head in disbelief. ‘That’s your family gift? You can change shape?’

Frank shuffled his feet. ‘Um … yeah. Periclymenus, my ancestor, the Argonaut – he could do that. He passed down the ability.’

‘And he got that gift from Poseidon,’ Percy said. ‘That’s completely unfair. I can’t turn into animals.’

Frank stared at him. ‘Unfair? You can breathe underwater and blow up glaciers and summon freaking hurricanes – and it’s unfair that I can be an elephant?’

Percy considered. ‘Okay. I guess you got a point. But next time I say you’re totally beast -’

‘Just shut up,’ Frank said. ‘Please.’

Percy cracked a smile.

‘If you guys are done,’ Hazel said, ‘we need to go. Camp Jupiter is under attack. They could use that gold eagle.’

Percy nodded. ‘One thing first, though. Hazel, there’s about a ton of Imperial gold weapons and armour at the bottom of the bay now, plus a really nice chariot. I’m betting that stuff could come in handy …’

It took them a long time – too long – but they all knew those weapons could make the difference between victory and defeat if they got them back to camp in time.

Hazel used her abilities to levitate some items from the bottom of the sea. Percy swam down and brought up more. Even Frank helped by turning into a seal, which was kind of cool, though Percy claimed his breath smelled like fish.

It took all three of them to raise the chariot, but finally they’d managed to haul everything ashore to a black sand beach near the base of the glacier. They couldn’t fit everything in the chariot, but they used Frank’s rope to strap down most of the gold weapons and the best pieces of armour.

‘It looks like Santa’s sleigh,’ Frank said. ‘Can Arion even pull that much?’

Arion huffed.

‘Hazel,’ Percy said, ‘I am seriously going to wash your horse’s mouth with soap. He says, yes, he can pull it, but he needs food.’

Hazel picked up an old Roman dagger, a pugio. It was bent and dull, so it wouldn’t be much good in a fight, but it looked like solid Imperial gold.

‘Here you go, Arion,’ she said. ‘High-performance fuel.’

The horse took the dagger in his teeth and chewed it like an apple. Frank made a silent oath never to put his hand near that horse’s mouth.

‘I’m not doubting Arion’s strength,’ he said carefully, ‘but will the chariot hold up? The last one -’

‘This one has Imperial gold wheels and axle,’ Percy said. ‘It should hold.’

‘If not,’ Hazel said, ‘this is going to be a short trip. But we’re out of time. Come on!’

Frank and Percy climbed into the chariot. Hazel swung up onto Arion’s back.

‘Giddyup!’ she yelled.

The horse’s sonic boom echoed across the bay. They sped south, avalanches tumbling down the mountains as they passed.

XLIX Percy

FOUR HOURS.

That’s how long it took the fastest horse on the planet to get from Alaska to San Francisco Bay, heading straight over the water down the North-west Coast.

That’s also how long it took for Percy’s memory to return completely. The process had started in Portland when he had drunk the gorgon’s blood, but his past life had still been maddeningly fuzzy. Now, as they headed back into the Olympian gods’ territory, Percy remembered everything: the war with Kronos; his sixteenth birthday at Camp Half-Blood; his trainer Chiron the centaur; his best friend, Grover; his brother, Tyson; and most of all Annabeth – two great months of dating, and then BOOM. He’d been abducted by the alien known as Hera. Or Juno … whatever.

Eight months of his life stolen. Next time Percy saw the Queen of Olympus, he was definitely going to give her
