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 armor 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, 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 center 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 armor was ripped so that his label just said ant.
The veterans and Lares on the eastern flank were being pushed toward 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 honor.”
“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-gray 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 barreled 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 armor with a glittering gold belt around 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 toward 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 toward 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.
