The House of Hades(Heroes of Olympus, Book 4)

FRANK



DESPITE THE MIDDAY HEAT and the raging storm of death energy, a group of tourists was climbing over the ruins. Fortunately there weren’t many and they didn’t give the demigods a second look.

After the crowds in Rome, Frank had stopped worrying too much about getting noticed. If they could fly their warship into the Roman Colosseum with ballistae blazing and not even cause a traffic slowdown, he figured they could get away with anything.

Nico led the way. At the top of the hill, they climbed over an old retaining wall and down into an excavated trench. Finally they arrived at a stone doorway leading straight into the side of the hill. The death storm seemed to originate right above their heads. Looking up at the swirling tentacles of darkness, Frank felt like he was trapped at the bottom of a flushing toilet bowl. That really didn’t calm his nerves.

Nico faced the group. ‘From here, it gets tough.’

‘Sweet,’ Leo said. ‘’Cause so far I’ve totally been pulling my punches.’

Nico glared at him. ‘We’ll see how long you keep your sense of humour. Remember, this is where pilgrims came to commune with dead ancestors. Underground, you may see things that are hard to look at, or hear voices trying to lead you astray in the tunnels. Frank, do you have the barley cakes?’

‘What?’ Frank had been thinking about his grandmother and his mom, wondering if they might appear to him. For the first time in days, the voices of Ares and Mars had started to argue again in the back of Frank’s mind, debating their favourite forms of violent death.

‘I’ve got the cakes,’ Hazel said. She pulled out the magical barley crackers they’d made from the grain Triptolemus had given them in Venice.

‘Eat up,’ Nico advised.

Frank chewed his cracker of death and tried not to gag. It reminded him of a cookie made with sawdust instead of sugar.

‘Yum,’ Piper said. Even the daughter of Aphrodite couldn’t avoid making a face.

‘Okay.’ Nico choked down the last of his barley. ‘That should protect us from the poison.’

‘Poison?’ Leo asked. ‘Did I miss the poison? ’Cause I love poison.’

‘Soon enough,’ Nico promised. ‘Just stick close together, and maybe we can avoid getting lost or going insane.’

On that happy note, Nico led them underground.

The tunnel spiralled gently downwards, the ceiling supported by white stone arches that reminded Frank of a whale’s rib cage.

As they walked, Hazel ran her hands along the masonry. ‘This wasn’t part of a temple,’ she whispered. ‘This was … the basement for a manor house, built in later Greek times.’

Frank found it eerie how Hazel could tell so much about an underground place just by being there. He’d never known her to be mistaken.

‘A manor house?’ he asked. ‘Please don’t tell me we’re in the wrong place.’

‘The House of Hades is below us,’ Nico assured him. ‘But Hazel’s right, these upper levels are much newer. When the archaeologists first excavated this site, they thought they’d found the Necromanteion. Then they realized the ruins were too recent, so they decided it was the wrong spot. They were right the first time. They just didn’t dig deep enough.’

They turned a corner and stopped. In front of them, the tunnel ended in a huge block of stone.

‘A cave-in?’ Jason asked.

‘A test,’ Nico said. ‘Hazel, would you do the honours?’

Hazel stepped forward. She placed her hand on the rock, and the entire boulder crumbled to dust.

The tunnel shuddered. Cracks spread across the ceiling. For a terrifying moment, Frank imagined they’d all be crushed under tons of earth – a disappointing way to die, after all they’d been through. Then the rumbling stopped. The dust settled.

A set of stairs curved deeper into the earth, the barrelled ceiling held up by more repeating arches, closer together and carved from polished black stone. The descending arches made Frank feel dizzy, as if he were looking into an endlessly reflecting mirror. Painted on the walls were crude pictures of black cattle marching downwards.

‘I really don’t like cows,’ Piper muttered.

‘Agreed,’ Frank said.

‘Those are the cattle of Hades,’ Nico said. ‘It’s just a symbol of –’

‘Look.’ Frank pointed.

On the first step of the stairwell, a golden chalice gleamed. Frank was pretty sure it hadn’t been there a moment before. The cup was full of dark-green liquid.

‘Hooray,’ Leo said halfheartedly. ‘I suppose that’s our poison.’

Nico picked up the chalice. ‘We’re standing at the ancient entrance of the Necromanteion. Odysseus came here, and dozens of other heroes, seeking advice from the dead.’

‘Did the dead advise them to leave immediately?’ Leo asked.

‘I would be fine with that,’ Piper admitted.

Nico drank from the chalice, then offered it to Jason. ‘You asked me about trust, and taking a risk? Well, here you go, son of Jupiter. How much do you trust me?’

Frank wasn’t sure what Nico was talking about, but Jason didn’t hesitate. He took the cup and drank.

They passed it around, each taking a sip of poison. As he waited his turn, Frank tried to keep his legs from shaking and his gut from churning. He wondered what his grandmother would say if she could see him.

Stupid, Fai Zhang! she would probably scold. If all your friends were drinking poison, would you do it too?

Frank went last. The taste of the green liquid reminded him of spoiled apple juice. He drained the chalice. It turned to smoke in his hands.

Nico nodded, apparently satisfied. ‘Congratulations. Assuming the poison doesn’t kill us, we should be able to find our way through the Necromanteion’s first level.’

‘Just the first level?’ Piper asked.

Nico turned to Hazel and gestured at the stairs. ‘After you, sister.’

In no time, Frank felt completely lost. The stairs split in three different directions. As soon as Hazel chose a path, the stairs split again. They wound their way through interconnecting tunnels and rough-hewn burial chambers that all looked the same – the walls carved with dusty niches that might once have held bodies. The arches over the doors were painted with black cows, white poplar trees and owls.

‘I thought the owl was Minerva’s symbol,’ Jason murmured.

‘The screech owl is one of Hades’s sacred animals,’ Nico said. ‘Its cry is a bad omen.’

‘This way.’ Hazel pointed to a doorway that looked the same as all the others. ‘It’s the only one that won’t collapse on us.’

‘Good choice, then,’ Leo said.

Frank began to feel like he was leaving the world of the living. His skin tingled, and he wondered if it was a side effect of the poison. The pouch with his firewood seemed heavier on his belt. In the eerie glow of their magic weapons, his friends looked like flickering ghosts.

Cold air brushed against his face. In his mind, Ares and Mars had gone silent, but Frank thought he heard other voices whispering in the side corridors, beckoning him to veer off course, to come closer and listen to them speak.

Finally they reached an archway carved in the shape of human skulls – or maybe they were human skulls embedded in the rock. In the purple light of Diocletian’s sceptre, the hollow eye sockets seemed to blink.

Frank almost hit the ceiling when Hazel put a hand on his arm.

‘This is the entrance to the second level,’ she said. ‘I’d better take a look.’

Frank hadn’t even realized that he’d moved in front of the doorway.

‘Uh, yeah …’ He made way for her.

Hazel traced her fingers across the carved skulls. ‘No traps on the doorway, but … something is strange here. My underground sense is – is fuzzy, like someone is working against me, hiding what’s ahead of us.’

‘The sorceress that Hecate warned you about?’ Jason guessed. ‘The one Leo saw in his dream? What was her name?’

Hazel chewed her lip. ‘It would be safer not to say her name. But stay alert. One thing I’m sure of: from this point on, the dead are stronger than the living.’

Frank wasn’t sure how she knew that, but he believed her. The voices in the darkness seemed to whisper louder. He caught glimpses of movement in the shadows. From the way his friends’ eyes darted around, he guessed they were seeing things too.

‘Where are the monsters?’ he wondered aloud. ‘I thought Gaia had an army guarding the Doors.’

‘Don’t know,’ Jason said. His pale skin looked as green as the poison from the chalice. ‘At this point I’d almost prefer a straight-up fight.’

‘Careful what you wish for, man.’ Leo summoned a ball of fire to his hand, and for once Frank was glad to see the flames. ‘Personally, I’m hoping nobody’s home. We walk in, find Percy and Annabeth, destroy the Doors of Death and walk out. Maybe stop at the gift shop.’

‘Yeah,’ Frank said. ‘That’ll happen.’

The tunnel shook. Rubble rained down from the ceiling.

Hazel grabbed Frank’s hand. ‘That was close,’ she muttered. ‘These passageways won’t take much more.’

‘The Doors of Death just opened again,’ Nico said.

‘It’s happening like every fifteen minutes,’ Piper noted.

‘Every twelve,’ Nico corrected, though he didn’t explain how he knew. ‘We’d better hurry. Percy and Annabeth are close. They’re in danger. I can sense it.’

As they travelled deeper, the corridors widened. The ceilings rose to six metres high, decorated with elaborate paintings of owls in the branches of white poplars. The extra space should have made Frank feel better, but all he could think about was the tactical situation. The tunnels were big enough to accommodate large monsters, even giants. There were blind corners everywhere, perfect for ambushes. Their group could be flanked or surrounded easily. They would have no good options for retreat.

All of Frank’s instincts told him to get out of these tunnels. If no monsters were visible, that just meant they were hiding, waiting to spring a trap. Even though Frank knew that, there wasn’t much he could do about it. They had to find the Doors of Death.

Leo held his fire close to the walls. Frank saw Ancient Greek graffiti scratched into the stone. He couldn’t read Ancient Greek, but he guessed they were prayers or supplications to the dead, written by pilgrims thousands of years ago. The tunnel floor was littered with ceramic shards and silver coins.

‘Offerings?’ Piper guessed.

‘Yes,’ Nico said. ‘If you wanted your ancestors to appear, you had to make an offering.’

‘Let’s not make an offering,’ Jason suggested.

Nobody argued.

‘The tunnel from here is unstable,’ Hazel warned. ‘The floor might … well, just follow me. Step exactly where I step.’

She made her way forward. Frank walked right behind her – not because he felt particularly brave but because he wanted to be close if Hazel needed his help. The voices of the war gods were arguing again in his ears. He could sense danger – very close now.

Fai Zhang.

He stopped cold. That voice … it wasn’t Ares or Mars. It seemed to come from right next to him, like someone whispering in his ear.

‘Frank?’ Jason whispered behind him. ‘Hazel, hold up a second. Frank, what’s wrong?’

‘Nothing,’ Frank murmured. ‘I just –’

Pylos, the voice said. I await you in Pylos.

Frank felt like the poison was bubbling back up his throat. He’d been scared plenty of times before. He’d even faced the god of Death.

But this voice terrified him in a different way. It resonated right down to his bones, as if it knew everything about him – his curse, his history, his future.

His grandmother had always been big on honouring the ancestors. It was a Chinese thing. You had to appease ghosts. You had to take them seriously.

Frank had always thought his grandmother’s superstitions were silly. Now he changed his mind. He had no doubt … the voice that spoke to him was one of his ancestors.

‘Frank, don’t move.’ Hazel sounded alarmed.

He looked down and realized he’d been about to step out of line.

To survive, you must lead, the voice said. At the break, you must take charge.

‘Lead where?’ he asked aloud.

Then the voice was gone. Frank could feel its absence, as if the humidity had suddenly dropped.

‘Uh, big guy?’ Leo said. ‘Could you not freak out on us? Please and thank you.’

Frank’s friends were all looking at him with concern.

‘I’m okay,’ he managed. ‘Just … a voice.’

Nico nodded. ‘I did warn you. It’ll only get worse. We should –’

Hazel held up her hand for silence. ‘Wait here, everybody.’

Frank didn’t like it, but she forged ahead alone. He counted to twenty-three before she came back, her face drawn and pensive.

‘Scary room ahead,’ she warned. ‘Don’t panic.’

‘Those two things don’t go together,’ Leo murmured. But they followed Hazel into the cavern.

The place was like a circular cathedral, with a ceiling so high it was lost in the gloom. Dozens of other tunnels led off in different directions, each echoing with ghostly voices. The thing that made Frank nervous was the floor. It was a gruesome mosaic of bones and gems – human femurs, hip bones and ribs twisted and fused together into a smooth surface, dotted with diamonds and rubies. The bones formed patterns, like skeletal contortionists tumbling together, curling to protect the precious stones – a dance of death and riches.

‘Touch nothing,’ Hazel said.

‘Wasn’t planning on it,’ Leo muttered.

Jason scanned the exits. ‘Which way now?’

For once, Nico looked uncertain. ‘This should be the room where the priests invoked the most powerful spirits. One of these passages leads deeper into the temple, to the third level and the altar of Hades himself. But which –?’

‘That one.’ Frank pointed. In a doorway at the opposite end of the room, a ghostly Roman legionnaire beckoned to them. His face was misty and indistinct, but Frank got the feeling the ghost was looking directly at him.

Hazel frowned. ‘Why that one?’

‘You don’t see the ghost?’ Frank asked.

‘Ghost?’ Nico asked.

Okay … if Frank was seeing a ghost that the Underworld kids couldn’t see, something was definitely wrong. He felt like the floor was vibrating underneath him. Then he realized it was vibrating.

‘We need to get to that exit,’ he said. ‘Now!’

Hazel almost had to tackle him to restrain him. ‘Wait, Frank! This floor is not stable, and underneath … well, I’m not sure what’s underneath. I need to scout a safe path.’

‘Hurry, then,’ he urged.

He drew his bow and herded Hazel along as fast as he dared. Leo scrambled behind him to provide light. The others guarded the rear. Frank could tell he was scaring his friends, but he couldn’t help it. He knew in his gut they had only seconds before …

In front of them, the legionnaire ghost vaporized. The cavern reverberated with monstrous roars – dozens, maybe hundreds of enemies coming from every direction. Frank recognized the throaty bellow of the Earthborn, the screech of gryphons, the guttural war cries of Cyclopes – all sounds he remembered from the Battle of New Rome, amplified underground, echoing in his head even louder than the war god’s voices.

‘Hazel, don’t stop!’ Nico ordered. He pulled the sceptre of Diocletian from his belt. Piper and Jason drew their swords as the monsters spilled into the cavern.

A vanguard of six-armed Earthborn threw a volley of stones that shattered the bone-and-jewel floor like ice. A fissure spread across the centre of the room, coming straight towards Leo and Hazel.

No time for caution. Frank tackled his friends, and the three of them skidded across the cavern, landing at the edge of the ghost’s tunnel as rocks and spears flew overhead.

‘Go!’ Frank yelled. ‘Go, go!’

Hazel and Leo scrambled into the tunnel, which seemed to be the only one free of monsters. Frank wasn’t sure that was a good sign.

Two metres in, Leo turned. ‘The others!’

The entire cavern shuddered. Frank looked back and his courage crumbled to dust. Dividing the cavern was a new fifteen-metre-wide chasm, spanned only by two rickety stretches of bone flooring. The bulk of the monster army was on the opposite side, howling in frustration and throwing whatever they could find, including each other. Some attempted to cross the bridges, which creaked and crackled under their weight.

Jason, Piper and Nico stood on the near side of the chasm, which was good, but they were surrounded by a ring of Cyclopes and hellhounds. More monsters kept pouring in from the side corridors, while gryphons wheeled overhead, undeterred by the crumbling floor.

The three demigods would never make it to the tunnel. Even if Jason tried to fly them, they’d be shot out of the air.

Frank remembered the voice of his ancestor: At the break, you must take charge.

‘We have to help them,’ Hazel said.

Frank’s mind raced, doing battle calculations. He saw exactly what would happen – where and when his friends would be overwhelmed, how all six of them would die here in this cavern … unless Frank changed the equation.

‘Nico!’ he yelled. ‘The sceptre.’

Nico raised Diocletian’s sceptre, and the cavern air shimmered purple. Ghosts climbed from the fissure and seeped from the walls – an entire Roman legion in full battle gear. They began taking on physical form, like walking corpses, but they seemed confused. Jason yelled in Latin, ordering them to form ranks and attack. The undead just shuffled among the monsters, causing momentary confusion, but that wouldn’t last.

Frank turned to Hazel and Leo. ‘You two keep going.’

Hazel’s eyes widened. ‘What? No!’

‘You have to.’ It was the hardest thing Frank had ever done, but he knew it was the only choice. ‘Find the Doors. Save Annabeth and Percy.’

‘But –’ Leo glanced over Frank’s shoulder. ‘Hit the deck!’

Frank dived for cover as a volley of rocks slammed overhead. When he managed to get up, coughing and covered in dust, the entrance to the tunnel was gone. An entire section of wall had collapsed, leaving a slope of smoking rubble.

‘Hazel …’ Frank’s voice broke. He had to hope she and Leo were alive on the other side. He couldn’t afford to think otherwise.

Anger swelled in his chest. He turned and charged towards the monster army.

FRANK



FRANK WAS NO EXPERT ON GHOSTS, but the dead legionnaires must have all been demigods, because they were totally ADHD.

They clawed their way out of the pit, then milled about aimlessly, chest-bumping each other for no apparent reason, pushing one another back into the chasm, shooting arrows into the air as if trying to kill flies and occasionally, out of sheer luck, throwing a javelin, a sword or an ally in the direction of the enemy.

Meanwhile, the army of monsters got thicker and angrier. Earthborn threw volleys of stones that ploughed into the zombie legionnaires, crushing them like paper. Female demons with mismatched legs and fiery hair (Frank guessed they were empousai) gnashed their fangs and shouted orders at the other monsters. A dozen Cyclopes advanced on the crumbling bridges, while seal-shaped humanoids – telkhines, like Frank had seen in Atlanta – lobbed vials of Greek fire across the chasm. There were even some wild centaurs in the mix, shooting flaming arrows and trampling their smaller allies under hoof. In fact, most of the enemy seemed to be armed with some kind of fiery weapon. Despite his new fireproof pouch, Frank found that extremely uncool.

He pushed through the crowd of dead Romans, shooting down monsters until his arrows were spent, slowly making his way towards his friends.

A little late, he realized – duh – he should turn into something big and powerful, like a bear or a dragon. As soon as the thought occurred, pain flared in his arm. He stumbled, looked down and was astonished to find an arrow shaft protruding from his left biceps. His sleeve was soaked with blood.

The sight made him dizzy. Mostly it made him angry. He tried to turn into a dragon, with no luck. The pain made it too hard to focus. Maybe he couldn’t change shape while wounded.

Great, he thought. Now I find out.

He dropped his bow and picked up a sword from a fallen … well, he actually wasn’t sure what it was – some sort of reptilian lady warrior with snake trunks instead of legs. He slashed his way forward, trying to ignore the pain and the blood dripping down his arm.

About five metres ahead, Nico was swinging his black sword with one hand, holding the sceptre of Diocletian aloft with the other. He kept shouting orders at the legionnaires, but they paid him no attention.

Of course not, Frank thought. He’s Greek.

Jason and Piper stood at Nico’s back. Jason summoned gusts of wind to blast aside javelins and arrows. He deflected a vial of Greek fire right up the throat of a gryphon, which burst into flames and spiralled into the pit. Piper put her new sword to good use, while spraying food from the cornucopia in her other hand – using hams, chickens, apples and oranges as interceptor missiles. The air above the chasm turned into a fireworks show of flaming projectiles, exploding rocks and fresh produce.

Still, Frank’s friends couldn’t hold out forever. Jason’s face was already beaded with sweat. He kept shouting in Latin: ‘Form ranks!’ But the dead legionnaires wouldn’t listen to him, either. Some of the zombies were helpful just by standing in the way, blocking monsters and taking fire. If they kept getting mowed down, though, there wouldn’t be enough of them left to organize.

‘Make way!’ Frank shouted. To his surprise, the dead legionnaires parted for him. The closest ones turned and stared at him with blank eyes, as if waiting for further orders.

‘Oh, great …’ Frank mumbled.

In Venice, Mars had warned him that his true test of leader-ship was coming. Frank’s ghostly ancestor had urged him to take charge. But, if these dead Romans wouldn’t listen to Jason, why should they listen to him? Because he was a child of Mars, or maybe because …

The truth hit him. Jason wasn’t quite Roman any more. His time at Camp Half-Blood had changed him. Reyna had recognized that. Apparently, so did the undead legionnaires. If Jason no longer gave off the right sort of vibe or aura of a Roman leader …

Frank made it to his friends as a wave of Cyclopes crashed into them. He lifted his sword to parry a Cyclops’s club, then stabbed the monster in the leg, sending him backwards into the pit. Another one charged. Frank managed to impale him, but blood loss was making him weak. His vision blurred. His ears rang.

He was dimly aware of Jason on his left flank, deflecting the incoming missiles with wind; Piper on his right, yelling charmspeak commands – encouraging the monsters to attack each other or take a refreshing jump into the chasm.

‘It’ll be fun!’ she promised.

A few listened, but across the pit the empousai were counter-ing her orders. Apparently they had charmspeak too. The monsters crowded so thickly around Frank that he could barely use his sword. The stench of their breath and body odour was almost enough to knock him out, even without the arrow throbbing in his arm.

What was Frank supposed to do? He’d had a plan, but his thoughts were getting fuzzy.

‘Stupid ghosts!’ Nico shouted.

‘They won’t listen!’ Jason agreed.

That was it. Frank had to make the ghosts listen.

He summoned all his strength and yelled, ‘Cohorts – lock shields!’

The zombies around him stirred. They lined up in front of Frank, putting their shields together in a ragged defensive formation. But they were moving too slowly, like sleepwalkers, and only a few had responded to his voice.

‘Frank, how did you do that?’ Jason yelled.

Frank’s head swam with pain. He forced himself not to pass out. ‘I’m the ranking Roman officer,’ he said. ‘They – uh, they don’t recognize you. Sorry.’

Jason grimaced, but he didn’t look particularly surprised. ‘How can we help?’

Frank wished he had an answer. A gryphon soared overhead, almost decapitating him with its talons. Nico smacked it with the sceptre of Diocletian, and the monster veered into a wall.

‘Orbem formate!’ Frank ordered.

About two dozen zombies obeyed, struggling to form a defensive ring around Frank and his friends. It was enough to give the demigods a little respite, but there were too many enemies pressing forward. Most of the ghostly legionnaires were still wandering around in a daze.

‘My rank,’ Frank realized.

‘All these monsters are rank!’ Piper yelled, stabbing a wild centaur.

‘No,’ Frank said. ‘I’m only a centurion.’

Jason cursed in Latin. ‘He means he can’t control a whole legion. He’s not of high enough rank.’

Nico swung his black sword at another gryphon. ‘Well, then, promote him!’

Frank’s mind was sluggish. He didn’t understand what Nico was saying. Promote him? How?

Jason shouted in his best drill-sergeant voice: ‘Frank Zhang! I, Jason Grace, praetor of the Twelfth Legion Fulminata, give you my final order: I resign my post and give you emergency field promotion to praetor, with the full powers of that rank. Take command of this legion!’

Frank felt as if a door had opened somewhere in the House of Hades, letting in a blast of fresh air that swept through the tunnels. The arrow in his arm suddenly didn’t matter. His thoughts cleared. His eyesight sharpened. The voices of Mars and Ares spoke in his mind, strong and unified: Break them!

Frank hardly recognized his own voice when he yelled: ‘Legion, agmen formate!’

Instantly, every dead legionnaire in the cavern drew his sword and raised his shield. They scrambled towards Frank’s position, pushing and hacking monsters out of their way until they stood shoulder to shoulder with the comrades, arranging themselves in a square formation. Stones, javelins and fire rained down, but now Frank had a disciplined defensive line sheltering them behind a wall of bronze and leather.

‘Archers!’ Frank yelled. ‘Eiaculare flammas!’

He didn’t hold out much hope the command would work. The zombies’ bows couldn’t be in good shape. But, to his surprise, several dozen ghostly skirmishers nocked arrows in unison. Their arrowheads caught fire spontaneously and a flaming wave of death arced over the legion’s line, straight into the enemy. Cyclopes fell. Centaurs stumbled. A telkhine shrieked and ran in circles with a burning arrow impaled in his forehead.

Frank heard a laugh behind him. He glanced back and couldn’t believe what he saw. Nico di Angelo was actually smiling.

‘That’s more like it,’ Nico said. ‘Let’s turn this tide!’

‘Cuneum formate!’ Frank yelled. ‘Advance with pila!’

The zombie line thickened in the centre, forming a wedge designed to break through the enemy host. They lowered their spears in a bristling row and pushed forward.

Earthborn wailed and threw boulders. Cyclopes smashed their fists and clubs against the locked shields, but the zombie legionnaires were no longer paper targets. They had inhuman strength, hardly wavering under the fiercest attacks. Soon the floor was covered with monster dust. The line of javelins chewed through the enemy like a set of giant teeth, felling ogres and snake women and hellhounds. Frank’s archers shot gryphons out of the air and caused chaos in the main body of the monster army across the chasm.

Frank’s forces began to take control of their side of the cavern. One of the stone bridges collapsed, but more monsters kept pouring over the other one. Frank would have to stop that.

‘Jason,’ he called, ‘can you fly a few legionnaires across the pit? The enemy’s left flank is weak – see? Take it!’

Jason smiled. ‘With pleasure.’

Three dead Romans rose into the air and flew across the chasm. Then three more joined them. Finally Jason flew himself across and his squad began cutting through some very surprised-looking telkhines, spreading fear through the enemy’s ranks.

‘Nico,’ Frank said, ‘keep trying to raise the dead. We need more numbers.’

‘On it.’ Nico lifted the sceptre of Diocletian, which glowed even darker purple. More ghostly Romans seeped from the walls to join the fight.

Across the chasm, empousai shouted commands in a language Frank didn’t know, but the gist was obvious. They were trying to shore up their allies and keep them charging across the bridge.

‘Piper!’ Frank yelled. ‘Counter those empousai! We need some chaos.’

‘Thought you’d never ask.’ She started catcalling at the female demons: ‘Your makeup is smeared! Your friend called you ugly! That one is making a face behind your back!’ Soon the vampire ladies were too busy fighting one another to shout any commands.

The legionnaires moved forward, keeping up the pressure. They had to take the bridge before Jason got overwhelmed.

‘Time to lead from the front,’ Frank decided. He raised his borrowed sword and called for a charge.
LXVIII





FRANK



FRANK DIDN’T NOTICE THAT HE WAS GLOWING. Later Jason told him that the blessing of Mars had shrouded him in red light, like it had in Venice. Javelins couldn’t touch him. Rocks somehow got deflected. Even with an arrow sticking out of his left biceps, Frank had never felt so full of energy.

The first Cyclops he met went down so quickly it was almost a joke. Frank sliced him in half from shoulder to waist. The big guy exploded into dust. The next Cyclops backed up nervously, so Frank cut his legs out from under him and sent him into the pit.

The remaining monsters on their side of the chasm tried to retreat, but the legion cut them down.

‘Testudo formation!’ Frank shouted. ‘Single file, advance!’

Frank was the first one across the bridge. The dead followed, their shields locked on either side and over their heads, deflecting all attacks. As the last of the zombies crossed, the stone bridge crumbled into the darkness, but by then it didn’t matter.

Nico kept summoning more legionnaires to join the fight. Over the history of the empire, thousands of Romans had served and died in Greece. Now they were back, answering the call of Diocletian’s sceptre.

Frank waded forward, destroying everything in his path.

‘I will burn you!’ a telkhine squeaked, desperately waving a vial of Greek fire. ‘I have fire!’

Frank took him down. As the vial dropped towards the ground, Frank kicked it over the cliff before it could explode.

An empousa raked her claws across Frank’s chest, but Frank felt nothing. He sliced the demon into dust and kept moving. Pain was unimportant. Failure was unthinkable.

He was a leader of the legion now, doing what he was born to do – fighting the enemies of Rome, upholding its legacy, protecting the lives of his friends and comrades. He was Praetor Frank Zhang.

His forces swept the enemy away, breaking their every attempt to regroup. Jason and Piper fought at his side, yelling defiantly. Nico waded through the last group of Earthborn, slashing them into mounds of wet clay with his black Stygian sword.

Before Frank knew it, the battle was over. Piper chopped through the last empousa, who vaporized with an anguished wail.

‘Frank,’ Jason said, ‘you’re on fire.’

He looked down. A few drops of oil must have splattered on his trousers, because they were starting to smoulder. Frank batted at them until they stopped smoking, but he wasn’t particularly worried. Thanks to Leo, he no longer had to fear fire.

Nico cleared his throat. ‘Uh … you also have an arrow sticking through your arm.’

‘I know.’ Frank snapped off the point of the arrow and pulled out the shaft by the tail. He felt only a warm tugging sensation. ‘I’ll be fine.’

Piper made him eat a piece of ambrosia. As she bandaged his wound, she said, ‘Frank, you were amazing. Completely terrifying, but amazing.’

Frank had trouble processing her words. Terrifying couldn’t apply to him. He was just Frank.

His adrenalin drained away. He looked around him, wondering where all the enemies had gone. The only monsters left were his own undead Romans, standing in a stupor with their weapons lowered.

Nico held up his sceptre, its orb dark and dormant. ‘The dead won’t stay much longer, now that the battle is over.’

Frank faced his troops. ‘Legion!’

The zombie soldiers snapped to attention.

‘You fought well,’ Frank told them. ‘Now you may rest. Dismissed.’

They crumbled into piles of bones, armour, shields and weapons. Then even those disintegrated.

Frank felt as if he might crumble too. Despite the ambrosia, his wounded arm began to throb. His eyes were heavy with exhaustion. The blessing of Mars faded, leaving him depleted. But his work wasn’t done yet.

‘Hazel and Leo,’ he said. ‘We need to find them.’

His friends peered across the chasm. At the other end of the cavern, the tunnel Hazel and Leo had entered was buried under tons of rubble.

‘We can’t go that way,’ Nico said. ‘Maybe …’

Suddenly he staggered. He would have fallen if Jason hadn’t caught him.

‘Nico!’ Piper said. ‘What is it?’

‘The Doors,’ Nico said. ‘Something’s happening. Percy and Annabeth … we need to go now.’

‘But how?’ Jason said. ‘That tunnel is gone.’

Frank clenched his jaw. He hadn’t come this far to stand around helplessly while his friends were in trouble. ‘It won’t be fun,’ he said, ‘but there’s another way.’
