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

PERCY



PERCY HAD TAKEN HIS GIRLFRIEND on some romantic walks before. This wasn’t one of them.

They followed the River Phlegethon, stumbling over the glassy black terrain, jumping crevices and hiding behind rocks whenever the vampire girls slowed in front of them.

It was tricky to stay far enough back to avoid getting spotted but close enough to keep Kelli and her comrades in view through the dark hazy air. The heat from the river baked Percy’s skin. Every breath was like inhaling sulphur-scented fibreglass. When they needed a drink, the best they could do was sip some refreshing liquid fire.

Yep. Percy definitely knew how to show a girl a good time.

At least Annabeth’s ankle seemed to have healed. She was hardly limping at all. Her various cuts and scrapes had faded. She’d tied her blonde hair back with a strip of denim torn from her jeans, and in the fiery light of the river her grey eyes flickered. Despite being beat-up, sooty and dressed like a homeless person, she looked great to Percy.

So what if they were in Tartarus? So what if they stood a slim chance of surviving? He was so glad that they were together he had the ridiculous urge to smile.

Physically, Percy felt better too, though his clothes looked like he’d been through a hurricane of broken glass. He was thirsty, hungry and scared out of his mind (though he wasn’t going to tell Annabeth that), but he’d shaken off the hopeless cold of the River Cocytus. And as nasty as the firewater tasted it seemed to keep him going.

Time was impossible to judge. They trudged along, following the river as it cut through the harsh landscape. Fortunately the empousai weren’t exactly speed walkers. They shuffled on their mismatched bronze and donkey legs, hissing and fighting with each other, apparently in no hurry to reach the Doors of Death.

Once, the demons sped up in excitement and swarmed something that looked like a beached carcass on the riverbank. Percy couldn’t tell what it was – a fallen monster? An animal of some kind? The empousai attacked it with relish.

When the demons moved on, Percy and Annabeth reached the spot and found nothing left except a few splintered bones and glistening stains drying in the heat of the river. Percy had no doubt the empousai would devour demigods with the same gusto.

‘Come on.’ He led Annabeth gently away from the scene. ‘We don’t want to lose them.’

As they walked, Percy thought about the first time he’d fought the empousa Kelli at Goode High School’s freshman orientation, when he and Rachel Elizabeth Dare got trapped in the band hall. At the time, it had seemed like a hopeless situation. Now, he’d give anything to have a problem that simple. At least he’d been in the mortal world then. Here, there was nowhere to run.

Wow. When he started looking back on the war with Kronos as the good old days – that was sad. He kept hoping things would get better for Annabeth and him, but their lives just got more and more dangerous, as if the Three Fates were up there spinning their futures with barbed wire instead of thread just to see how much two demigods could tolerate.

After a few more miles, the empousai disappeared over a ridge. When Percy and Annabeth caught up, they found themselves at the edge of another massive cliff. The River Phlegethon spilled over the side in jagged tiers of fiery waterfalls. The demon ladies were picking their way down the cliff, jumping from ledge to ledge like mountain goats.

Percy’s heart crept into his throat. Even if he and Annabeth reached the bottom of the cliff alive, they didn’t have much to look forward to. The landscape below them was a bleak ash-grey plain bristling with black trees, like insect hair. The ground was pocked with blisters. Every once in a while, a bubble would swell and burst, disgorging a monster like a larva from an egg.

Suddenly Percy wasn’t hungry any more.

All the newly formed monsters were crawling and hobbling in the same direction – towards a bank of black fog that swallowed the horizon like a storm front. The Phlegethon flowed in the same direction until about halfway across the plain, where it met another river of black water – maybe the Cocytus? The two floods combined in a steaming, boiling cataract and flowed on as one towards the black fog.

The longer Percy looked into that storm of darkness, the less he wanted to go there. It could be hiding anything – an ocean, a bottomless pit, an army of monsters. But if the Doors of Death were in that direction it was their only chance to get home.

He peered over the edge of the cliff.

‘Wish we could fly,’ he muttered.

Annabeth rubbed her arms. ‘Remember Luke’s winged shoes? I wonder if they’re still down here somewhere.’

Percy remembered. Those shoes had been cursed to drag their wearer into Tartarus. They’d almost taken his best friend, Grover. ‘I’d settle for a hang glider.’

‘Maybe not a good idea.’ Annabeth pointed. Above them, dark winged shapes spiralled in and out of the blood-red clouds.

‘Furies?’ Percy wondered.

‘Or some other kind of demon,’ Annabeth said. ‘Tartarus has thousands.’

‘Including the kind that eats hang gliders,’ Percy guessed. ‘Okay, so we climb.’

He couldn’t see the empousai below them any more. They’d disappeared behind one of the ridges, but that didn’t matter. It was clear where he and Annabeth needed to go. Like all the maggot monsters crawling over the plains of Tartarus, they should head towards the dark horizon. Percy was just brimming with enthusiasm for that.

PERCY



AS THEY STARTED DOWN THE CLIFF, Percy concentrated on the challenges at hand: keeping his footing, avoiding rockslides that would alert the empousai to their presence and of course making sure he and Annabeth didn’t plummet to their deaths.

About halfway down the precipice, Annabeth said, ‘Stop, okay? Just a quick break.’

Her legs wobbled so badly, Percy cursed himself for not calling a rest earlier.

They sat together on a ledge next to a roaring fiery waterfall. Percy put his arm around Annabeth, and she leaned against him, shaking from exhaustion.

He wasn’t much better. His stomach felt like it had shrunk to the size of a gumdrop. If they came across any more monster carcasses, he was afraid he might pull an empousa and try to devour it.

At least he had Annabeth. They would find a way out of Tartarus. They had to. He didn’t think much of fates and prophecies, but he did believe in one thing: Annabeth and he were supposed to be together. They hadn’t survived so much just to get killed now.

‘Things could be worse,’ Annabeth ventured.

‘Yeah?’ Percy didn’t see how, but he tried to sound upbeat.

She snuggled against him. Her hair smelled of smoke, and if he closed his eyes he could almost imagine they were at the campfire at Camp Half-Blood.

‘We could’ve fallen into the River Lethe,’ she said. ‘Lost all our memories.’

Percy’s skin crawled just thinking about it. He’d had enough trouble with amnesia for one lifetime. Only last month, Hera had erased his memories to put him among the Roman demigods. Percy had stumbled into Camp Jupiter with no idea who he was or where he came from. And a few years before that he’d fought a Titan on the banks of the Lethe, near Hades’s palace. He’d blasted the Titan with water from that river and completely wiped his memory clean. ‘Yeah, the Lethe,’ he muttered. ‘Not my favourite.’

‘What was the Titan’s name?’ Annabeth asked.

‘Uh … Iapetus. He said it meant the Impaler or something.’

‘No, the name you gave him after he lost his memory. Steve?’

‘Bob,’ Percy said.

Annabeth managed a weak laugh. ‘Bob the Titan.’

Percy’s lips were so parched, it hurt to smile. He wondered what had happened to Iapetus after they’d left him in Hades’s palace … if he was still content being Bob, friendly, happy and clueless. Percy hoped so, but the Underworld seemed to bring out the worst in everyone – monsters, heroes and gods.

He gazed across the ashen plains. The other Titans were supposed to be here in Tartarus – maybe bound in chains, or roaming aimlessly, or hiding in some of those dark crevices. Percy and his allies had destroyed the worst Titan, Kronos, but even his remains might be down here somewhere – a billion angry Titan particles floating through the blood-coloured clouds or lurking in that dark fog.

Percy decided not to think about that. He kissed Annabeth’s forehead. ‘We should keep moving. You want some more fire to drink?’

‘Ugh. I’ll pass.’

They struggled to their feet. The rest of the cliff looked impossible to descend – nothing more than a crosshatching of tiny ledges – but they kept climbing down.

Percy’s body went on autopilot. His fingers cramped. He felt blisters popping up on his ankles. He got shaky from hunger.

He wondered if they would die of starvation, or if the firewater would keep them going. He remembered the punishment of Tantalus, who’d been permanently stuck in a pool of water under a fruit tree but couldn’t reach either food or drink.

Jeez, Percy hadn’t thought about Tantalus in years. That stupid guy had been paroled briefly to serve as director at Camp Half-Blood. Probably he was back in the Fields of Punishment. Percy had never felt sorry for the jerk before, but now he was starting to sympathize. He could imagine what it would be like, getting hungrier and hungrier for eternity but never being able to eat.

Keep climbing, he told himself.

Cheeseburgers, his stomach replied.

Shut up, he thought.

With fries, his stomach complained.

A billion years later, with a dozen new blisters on his feet, Percy reached the bottom. He helped Annabeth down, and they collapsed on the ground.

Ahead of them stretched miles of wasteland, bubbling with monstrous larvae and big insect-hair trees. To their right, the Phlegethon split into branches that etched the plain, widening into a delta of smoke and fire. To the north, along the main route of the river, the ground was riddled with cave entrances. Here and there, spires of rock jutted up like exclamation points.

Under Percy’s hand, the soil felt alarmingly warm and smooth. He tried to grab a handful, then realized that, under a thin layer of dirt and debris, the ground was a single vast membrane … like skin.

He almost threw up, but forced himself not to. There was nothing in his stomach but fire.

He didn’t mention it to Annabeth, but he started to feel like something was watching them – something vast and malevolent. He couldn’t zero in on it, because the presence was all around them. Watching was the wrong word, too. That implied eyes, and this thing was simply aware of them. The ridges above them now looked less like steps and more like rows of massive teeth. The spires of rock looked like broken ribs. And if the ground was skin …

Percy forced those thoughts aside. This place was just freaking him out. That was all.

Annabeth stood, wiping soot from her face. She gazed towards the darkness on the horizon. ‘We’re going to be completely exposed, crossing this plain.’

About a hundred yards ahead of them, a blister burst on the ground. A monster clawed its way out … a glistening telkhine with slick fur, a seal-like body and stunted human limbs. It managed to crawl a few yards before something shot out of the nearest cave, so fast that Percy could only register a dark green reptilian head. The monster snatched the squealing telkhine in its jaws and dragged it into the darkness.

Reborn in Tartarus for two seconds, only to be eaten. Percy wondered if that telkhine would pop up in some other place in Tartarus, and how long it would take to re-form.

He swallowed down the sour taste of firewater. ‘Oh, yeah. This’ll be fun.’

Annabeth helped him to his feet. He took one last look at the cliffs, but there was no going back. He would’ve given a thousand golden drachmas to have Frank Zhang with them right now – good old Frank, who always seemed to show up when needed and could turn into an eagle or a dragon to fly them across this stupid wasteland.

They started walking, trying to avoid the cave entrances, sticking close to the bank of the river.

They were just skirting one of the spires when a glint of movement caught Percy’s eye – something darting between the rocks to their right.

A monster following them? Or maybe it was just some random baddie, heading for the Doors of Death.

Suddenly he remembered why they’d started following this route, and he froze in his tracks.

‘The empousai.’ He grabbed Annabeth’s arm. ‘Where are they?’

Annabeth scanned a three-sixty, her grey eyes bright with alarm.

Maybe the demon ladies had been snapped up by that reptile in the cave. If the empousai were still ahead of them, they should’ve been visible somewhere on the plains.

Unless they were hiding …

Too late, Percy drew his sword.

The empousai emerged from the rocks all around them – five of them forming a ring. A perfect trap.

Kelli limped forward on her mismatched legs. Her fiery hair burned across her shoulders like a miniature Phlegethon waterfall. Her tattered cheerleader outfit was splattered with rusty-brown stains, and Percy was pretty sure they weren’t ketchup. She fixed him with her glowing red eyes and bared her fangs.

‘Percy Jackson,’ she cooed. ‘How awesome! I don’t even have to return to the mortal world to destroy you!’

PERCY



PERCY RECALLED HOW DANGEROUS Kelli had been the last time they’d fought in the Labyrinth. Despite those mismatched legs, she could move fast when she wanted to. She’d dodged his sword strikes and would have eaten his face if Annabeth hadn’t stabbed her from behind.

Now she had four friends with her.

‘And your friend Annabeth is with you!’ Kelli hissed with laughter. ‘Oh, yeah, I totally remember her.’

Kelli touched her own sternum, where the tip of the knife had exited when Annabeth had stabbed her in the back. ‘What’s the matter, daughter of Athena? Don’t have your weapon? Bummer. I’d use it to kill you.’

Percy tried to think. He and Annabeth stood shoulder to shoulder as they had many times before, ready to fight. But neither of them was in good shape for battle. Annabeth was empty-handed. They were hopelessly outnumbered. There was nowhere to run. No help coming.

Briefly Percy considered calling for Mrs O’Leary, his hellhound friend who could shadow-travel. Even if she heard him, could she make it into Tartarus? This was where monsters went when they died. Calling her here might kill her, or turn her back to her natural state as a fierce monster. No … he couldn’t do that to his dog.

So, no help. Fighting was a long shot.

That left Annabeth’s favourite tactics: trickery, talk, delay.

‘So …’ he started, ‘I guess you’re wondering what we’re doing in Tartarus.’

Kelli snickered. ‘Not really. I just want to kill you.’

That would’ve been it, but Annabeth chimed in.

‘Too bad,’ she said. ‘Because you have no idea what’s going on in the mortal world.’

The other empousai circled, watching Kelli for a cue to attack, but the ex-cheerleader only snarled, crouching out of reach of Percy’s sword.

‘We know enough,’ Kelli said. ‘Gaia has spoken.’

‘You’re heading towards a major defeat.’ Annabeth sounded so confident, even Percy was impressed. She glanced at the other empousai, one by one, then pointed accusingly at Kelli. ‘This one claims she’s leading you to a victory. She’s lying. The last time she was in the mortal world, Kelli was in charge of keeping my friend Luke Castellan faithful to Kronos. In the end, Luke rejected him. He gave his life to expel Kronos. The Titans lost because Kelli failed. Now Kelli wants to lead you to another disaster.’

The other empousai muttered and shifted uneasily.

‘Enough!’ Kelli’s fingernails grew into long black talons. She glared at Annabeth as if imagining her sliced into small pieces.

Percy was pretty sure Kelli had had a thing for Luke Castellan. Luke had that effect on girls – even donkey-legged vampires – and Percy wasn’t sure bringing up his name was such a good idea.

‘The girl lies,’ Kelli said. ‘So the Titans lost. Fine! That was part of the plan to wake Gaia! Now the Earth Mother and her giants will destroy the mortal world, and we will totally feast on demigods!’

The other vampires gnashed their teeth in a frenzy of excitement. Percy had been in the middle of a school of sharks when the water was full of blood. That wasn’t nearly as scary as empousai ready to feed.

He prepared to attack, but how many could he dispatch before they overwhelmed him? It wouldn’t be enough.

‘The demigods have united!’ Annabeth yelled. ‘You’d better think twice before you attack us. Romans and Greeks will fight you together. You don’t stand a chance!’

The empousai backed up nervously, hissing, ‘Romani.’

Percy guessed they’d had experience with the Twelfth Legion before and it hadn’t worked out well for them.

‘Yeah, you bet Romani.’ Percy bared his forearm and showed them the brand he’d got at Camp Jupiter – the SPQR mark, with the trident of Neptune. ‘You mix Greek and Roman, and you know what you get? You get BAM!’

He stomped his foot, and the empousai scrambled back. One fell off the boulder where she’d been perched.

That made Percy feel good, but they recovered quickly and closed in again.

‘Bold talk,’ Kelli said, ‘for two demigods lost in Tartarus. Lower your sword, Percy Jackson, and I’ll kill you quickly. Believe me, there are worse ways to die down here.’

‘Wait!’ Annabeth tried again. ‘Aren’t empousai the servants of Hecate?’

Kelli curled her lip. ‘So?’

‘So Hecate is on our side now,’ Annabeth said. ‘She has a cabin at Camp Half-Blood. Some of her demigod children are my friends. If you fight us, she’ll be angry.’

Percy wanted to hug Annabeth, she was so brilliant.

One of the other empousai growled. ‘Is this true, Kelli? Has our mistress made peace with Olympus?’

‘Shut up, Serephone!’ Kelli screeched. ‘Gods, you’re annoying!’

‘I will not cross the Dark Lady.’

Annabeth took the opening. ‘You’d all be better following Serephone. She’s older and wiser.’

‘Yes!’ Serephone shrieked. ‘Follow me!’

Kelli struck so fast, Percy didn’t have the chance to raise his sword. Fortunately, she didn’t attack him. Kelli lashed out at Serephone. For half a second, the two demons were a blur of slashing claws and fangs.

Then it was over. Kelli stood triumphant over a pile of dust. From her claws hung the tattered remains of Serephone’s dress.

‘Any more issues?’ Kelli snapped at her sisters. ‘Hecate is the goddess of the Mist! Her ways are mysterious. Who knows which side she truly favours? She is also the goddess of the crossroads, and she expects us to make our own choices. I choose the path that will bring us the most demigod blood! I choose Gaia!’

Her friends hissed in approval.

Annabeth glanced at Percy, and he saw that she was out of ideas. She’d done what she could. She’d got Kelli to eliminate one of her own. Now there was nothing left but to fight.

‘For two years I churned in the void,’ Kelli said. ‘Do you know how completely annoying it is to be vaporized, Annabeth Chase? Slowly re-forming, fully conscious, in searing pain for months and years as your body regrows, then finally breaking the crust of this hellish place and clawing your way back to daylight? All because some little girl stabbed you in the back?’

Her baleful eyes held Annabeth’s. ‘I wonder what happens if a demigod is killed in Tartarus. I doubt it’s ever happened before. Let’s find out.’

Percy sprang, slashing Riptide in a huge arc. He cut one of the demons in half, but Kelli dodged and charged Annabeth. The other two empousai launched themselves at Percy. One grabbed his sword arm. Her friend jumped on his back.

Percy tried to ignore them and staggered towards Annabeth, determined to go down defending her if he had to, but Annabeth was doing pretty well. She tumbled to one side, evading Kelli’s claws, and came up with a rock in her hand, which she smacked into Kelli’s nose.

Kelli wailed. Annabeth scooped up gravel and flung it in the empousa’s eyes.

Meanwhile Percy thrashed from side to side, trying to throw off his empousa hitch-hiker, but her claws sank deeper into his shoulders. The second empousa held his arm, preventing him from using Riptide.

Out of the corner of his eye, he saw Kelli lunge, raking her talons across Annabeth’s arm. Annabeth screamed and fell.

Percy stumbled in her direction. The vampire on his back sank her teeth into his neck. Searing pain coursed through his body. His knees buckled.

Stay on your feet, he told himself. You have to beat them.

Then the other vampire bit his sword arm, and Riptide clattered to the ground.

That was it. His luck had finally run out. Kelli loomed over Annabeth, savouring her moment of triumph. The other two empousai circled Percy, their mouths slavering, ready for another taste.

Then a shadow fell across Percy. A deep war cry bellowed from somewhere above, echoing across the plains of Tartarus, and a Titan dropped onto the battlefield.
