Rick Riordan: The Son of Neptune

‘Bad Cyclops Lady!’ he bellowed. ‘General Tyson says GO AWAY!’

He hit her again, and Ma Gasket broke into dust.

Meanwhile Hazel charged around on Arion, slicing her spatha through one Cyclops after another, while Frank blinded the enemies with his talons.

Once every Cyclops within fifty yards had been reduced to ashes, Frank landed in front of his troops and transformed into a human. His centurion’s badge and Mural Crown gleamed on his winter jacket.

‘Fifth Cohort!’ he bellowed. ‘Get your Imperial gold weapons right here!’

The campers recovered from their shock and mobbed the chariot. Percy did his best to hand out equipment quickly.

‘Let’s go, let’s go!’ Dakota urged, grinning like a madman as he swigged red Kool-Aid from his flask. ‘Our comrades need help!’

Soon the Fifth Cohort was equipped with new weapons and shields and helmets. They weren’t exactly consistent. In fact they looked like they’d been shopping at a King Midas clearance sale. But they were suddenly the most powerful cohort in the legion.

‘Follow the eagle!’ Frank ordered. ‘To battle!’

The campers cheered. As Percy and Mrs O’Leary charged onward, the entire cohort followed – forty extremely shiny gold-plated warriors screaming for blood.

They slammed into a herd of wild centaurs that were attacking the Third Cohort. When the campers of the Third saw the eagle standard, they shouted insanely and fought with renewed effort.

The centaurs didn’t stand a chance. The two cohorts crushed them like a vice. Soon there was nothing left but piles of dust and assorted hooves and horns. Percy hoped Chiron would forgive him, but these centaurs weren’t like the Party Ponies he’d met before. They were some other breed. They had to be defeated.

‘Form ranks!’ the centurions shouted. The two cohorts came together, their military training kicking in. Shields locked, they marched into battle against the Earthborn.

Frank shouted, ‘ Pila! ’

A hundred spears bristled. When Frank yelled, ‘Fire!’ they sailed through the air – a wave of death cutting through the six-armed monsters. The campers drew swords and advanced towards the centre of the battle.

At the base of the aqueduct, the First and Second Cohorts were trying to encircle Polybotes, but they were taking a pounding. The remaining Earthborn threw barrage after barrage of stone and mud. Karpoi grain spirits – those horrible little piranha Cupids – were rushing through the tall grass abducting campers at random, pulling them away from the line. The giant himself kept shaking basilisks out of his hair. Every time one landed, the Romans panicked and ran. Judging from their corroded shields and the smoking plumes on their helmets, they’d already learned about the basilisks’ poison and fire.

Reyna soared above the giant, diving in with her javelin whenever he turned his attention to the ground troops. Her purple cloak snapped in the wind. Her golden armour gleamed. Polybotes jabbed his trident and swung his weighted net, but Scipio was almost as nimble as Arion.

Then Reyna noticed the Fifth Cohort marching to their aid with the eagle. She was so stunned that the giant almost swatted her out of the air, but Scipio dodged. Reyna locked eyes with Percy and gave him a huge smile.

‘Romans!’ Her voice boomed across the fields. ‘Rally to the eagle!’

Demigods and monsters alike turned and gawked as Percy bounded forward on his hellhound.

‘What is this?’ Polybotes demanded. ‘ What is this? ’

Percy felt a rush of power coursing through the standard’s staff. He raised the eagle and shouted, ‘Twelfth Legion Fulminata!’

Thunder shook the valley. The eagle let loose a blinding flash, and a thousand tendrils of lightning exploded from its golden wings – arcing in front of Percy like the branches of an enormous deadly tree, connecting with the nearest monsters, leaping from one to another, completely ignoring the Roman forces.

When the lightning stopped, the First and Second Cohorts were facing one surprised-looking giant and several hundred smoking piles of ash. The enemy’s centre line had been charred to oblivion.

The look on Octavian’s face was priceless. The centurion stared at Percy with shock, then outrage. Then, when his own troops started to cheer, he had no choice except to join the shouting: ‘Rome! Rome!’

The giant Polybotes backed up uncertainly, but Percy knew the battle wasn’t over.

The Fourth Cohort was still surrounded by Cyclopes. Even Hannibal the elephant was having a hard time wading through so many monsters. His black Kevlar armour was ripped so that his label just said ANT.

The veterans and Lares on the eastern flank were being pushed towards the city. The monsters’ siege tower was still hurling explosive green fireballs into the streets. The gorgons had disabled the giant eagles and now flew unchallenged over the giant’s remaining centaurs and the Earthborn, trying to rally them.

‘Stand your ground!’ Stheno yelled. ‘I’ve got free samples!’

Polybotes bellowed. A dozen fresh basilisks fell out of his hair, turning the grass to poison yellow. ‘You think this changes anything, Percy Jackson? I cannot be destroyed! Come forward, son of Neptune. I will break you!’

Percy dismounted. He handed Dakota the standard. ‘You are the cohort’s senior centurion. Take care of this.’

Dakota blinked, then he straightened with pride. He dropped his Kool-Aid flask and took the eagle. ‘I will carry it with honour.’

‘Frank, Hazel, Tyson,’ Percy said, ‘help the Fourth Cohort. I’ve got a giant to kill.’

He raised Riptide, but before he could advance, horns blew in the northern hills. Another army appeared on the ridge – hundreds of warriors in black-and-grey camouflage, armed with spears and shields. Interspersed among their ranks were a dozen battle forklifts, their sharpened tines gleaming in the sunset and flaming bolts nocked in their crossbows.

‘Amazons,’ Frank said. ‘Great.’

Polybotes laughed. ‘You see? Our reinforcements have arrived! Rome will fall today!’

The Amazons lowered their spears and charged down the hill. Their forklifts barrelled into battle. The giant’s army cheered – until the Amazons changed course and headed straight for the monsters’ intact eastern flank.

‘Amazons, forward!’ On the largest forklift stood a girl who looked like an older version of Reyna, in black combat armour with a glittering gold belt round her waist.

‘Queen Hylla!’ said Hazel. ‘She survived!’

The Amazon queen shouted: ‘To my sister’s aid! Destroy the monsters!’

‘Destroy!’ Her troops’ cry echoed through the valley.

Reyna wheeled her pegasus towards Percy. Her eyes gleamed. Her expression said: I could hug you right now . She shouted, ‘Romans! Advance!’

The battlefield descended into absolute chaos. Amazon and Roman lines swung towards the enemy like the Doors of Death themselves.

But Percy had only one goal. He pointed at the giant. ‘You. Me. To the finish.’

They met by the aqueduct, which had somehow survived the battle so far. Polybotes fixed that. He swiped his trident and smashed the nearest brick arch, unleashing a waterfall.

‘Go on, then, son of Neptune!’ Polybotes taunted. ‘Let me see your power! Does water do your bidding? Does it heal you? But I am born to oppose Neptune.’

The giant thrust his hand under the water. As the torrent passed through his fingers it turned dark green. He flung some at Percy, who instinctively deflected it with his will. The liquid splattered the ground in front of him. With a nasty hiss, the grass withered and smoked.

‘My touch turns water to poison,’ Polybotes said. ‘Let’s see what it does to your blood!’
