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

FRANK STUMBLED OUT OF THE BLACK HOUSE. The door shut behind him, and he collapsed against the wall, overcome with guilt. Fortunately the katoblepones had cleared off, or he might have just sat there and let them trample him. He deserved nothing better. He’d left Hazel inside, dying and defenseless, at the mercy of a crazy farmer god.

Kill farmers! Ares screamed in his head.

Return to the legion and fight Greeks! Mars said. What are we doing here?

Killing farmers! Ares screamed back.

“Shut up!” Frank yelled aloud. “Both of you!”

A couple of old ladies with shopping bags shuffled past. They gave Frank a strange look, muttered something in Italian, and kept going.

Frank stared miserably at Hazel’s cavalry sword, lying at his feet next to his backpack. He could run back to the Argo II and get Leo. Maybe Leo could fix the chariot.

But Frank somehow knew this wasn’t a problem for Leo. It was Frank’s task. He had to prove himself. Besides, the chariot wasn’t exactly broken. There was no mechanical problem. It was missing a serpent.

Frank could turn himself into a python. When he’d woken up that morning as a giant snake, perhaps it had been a sign from the gods. He didn’t want to spend the rest of his life turning the wheel of a farmer’s chariot, but if it meant saving Hazel…

No. There had to be another way.

Serpents, Frank thought. Mars.

Did his father have some connection to snakes? Mars’s sacred animal was the wild boar, not the serpent. Still, Frank was sure he’d heard something once.…

He could think of only one person to ask. Reluctantly, he opened his mind to the voices of the war god.

I need a snake, he told them. How?

Ha, ha! Ares screamed. Yes, the serpent!

Like that vile Cadmus, Mars said. We punished him for killing our dragon!

They both started yelling, until Frank thought his brain would split in half.

“Okay! Stop!”

The voices quieted.

“Cadmus,” Frank muttered. “Cadmus…”

The story came back to him. The demigod Cadmus had slain a dragon that happened to be a child of Ares. How Ares had ended up with a dragon for a son, Frank didn’t want to know; but as punishment for the dragon’s death, Ares turned Cadmus into a snake.

“So you can turn your enemies into snakes,” Frank said. “That’s what I need. I need to find an enemy. Then I need you to turn him into a snake.”

You think I would do that for you? Ares roared. You have not proven your worth!

Only the greatest hero could ask such a boon, Mars said. A hero like Romulus!

Too Roman! Ares shouted. Diomedes!

Never! Mars shouted back. That coward fell to Heracles!

Horatius, then, Ares suggested.

Mars went silent. Frank sensed a grudging agreement.

“Horatius,” Frank said. “Fine. If that’s what it takes, I’ll prove I’m as good as Horatius. Uh…what did he do?”

Images flooded into Frank’s mind. He saw a lone warrior standing on a stone bridge, facing an entire army massed on the far side of the Tiber River.

Frank remembered the legend. Horatius, the Roman general, had single-handedly held off a horde of invaders, sacrificing himself on that bridge to keep the barbarians from crossing the Tiber. By giving his fellow Romans time to finish their defenses, he’d saved the Republic.

Venice is overrun, Mars said, as Rome was about to be. Cleanse it!

Destroy them all! Ares said. Put them to the sword!

Frank pushed the voices to the back of his mind. He looked at his hands and was amazed they weren’t trembling.

For the first time in days, his thoughts were clear. He knew exactly what he needed to do. He didn’t know how he would pull it off. The odds of dying were excellent, but he had to try. Hazel’s life depended on him.

He strapped Hazel’s sword to his belt, morphed his backpack into a quiver and bow, and raced toward the piazza where he’d fought the cow monsters.

The plan had three phases: dangerous, really dangerous, and insanely dangerous.

Frank stopped at the old stone well. No katoblepones in sight. He drew Hazel’s sword and used it to pry up some cobblestones, unearthing a big tangle of spiky roots. The tendrils unfurled, exuding their stinky green fumes as they crept toward Frank’s feet.

In the distance, a katobleps’s foghorn moan filled the air. Others joined in from all different directions. Frank wasn’t sure how the monsters could tell he was harvesting their favorite food—maybe they just had an excellent sense of smell.

He had to move fast now. He sliced off a long cluster of vines and laced them through one of his belt loops, trying to ignore the burning and itching in his hands. Soon he had a glowing, stinking lasso of poisonous weeds. Hooray.

The first few katoblepones lumbered into the piazza, bellowing in anger. Green eyes glowed under their manes. Their long snouts blew clouds of gas, like furry steam engines.

Frank nocked an arrow. He had a momentary pang of guilt. These were not the worst monsters he’d met. They were basically grazing animals that happened to be poisonous.

Hazel is dying because of them, he reminded himself.

He let the arrow fly. The nearest katobleps collapsed, crumbling to dust. He nocked a second arrow, but the rest of the herd was almost on top of him. More were charging into the square from the opposite direction.

Frank turned into a lion. He roared defiantly and leaped toward the archway, straight over the heads of the second herd. The two groups of katoblepones slammed into each other, but quickly recovered and ran after him.

Frank hadn’t been sure the roots would still smell when he changed form. Usually his clothes and possessions just sort of melted into his animal shape, but apparently he still smelled like a yummy poison dinner. Each time he raced past a katobleps, it roared with outrage and joined the Kill Frank! Parade.

He turned onto a larger street and pushed through the crowds of tourists. What the mortals saw, he had no idea—a cat being chased by a pack of dogs? People cursed at Frank in about twelve different languages. Gelato cones went flying. A woman spilled a stack of carnival masks. One dude toppled into the canal.

When Frank glanced back, he had at least two dozen monsters on his tail, but he needed more. He needed all the monsters in Venice, and he had to keep the ones behind him enraged.

He found an open spot in the crowd and turned back into a human. He drew Hazel’s spatha—never his preferred weapon, but he was big enough and strong enough that the heavy cavalry sword didn’t bother him. In fact he was glad for the extra reach. He slashed the golden blade, destroying the first katobleps and letting the others bunch up in front of him.

He tried to avoid their eyes, but he could feel their gaze burning into him. He figured that if all these monsters breathed on him at once, their combined noxious cloud would be enough to melt him into a puddle. The monsters crowded forward and slammed into one another.

Frank yelled, “You want my poison roots? Come and get them!”

He turned into a dolphin and jumped into the canal. He hoped katoblepones couldn’t swim. At the very least, they seemed reluctant to follow him in, and he couldn’t blame them. The canal was disgusting—smelly and salty and as warm as soup—but Frank forged through it, dodging gondolas and speedboats, pausing occasionally to chitter dolphin insults at the monsters who followed him on the sidewalks. When he reached the nearest gondola dock, Frank turned back into a human again, stabbed a few more katoblepones to keep them angry, and took off running.

So it went.

After a while, Frank fell into a kind of daze. He attracted more monsters, scattered more crowds of tourists, and led his now massive following of katoblepones through the winding streets of the old city. Whenever he needed a quick escape, he dove into a canal as a dolphin, or turned into an eagle and soared overhead, but he never got too far ahead of his pursuers.

Whenever he felt like the monsters might be losing interest, he stopped on a rooftop and drew his bow, picking off a few of the katoblepones in the center of the herd. He shook his lasso of poison vines and insulted the monsters’ bad breath, stirring them into a fury. Then he continued the race.

He backtracked. He lost his way. Once he turned a corner and ran into the tail end of his own monster mob. He should have been exhausted, yet somehow he found the strength to keep going—which was good. The hardest part was yet to come.

He spotted a couple of bridges, but they didn’t look right. One was elevated and completely covered; no way could he get the monsters to funnel through it. Another was too crowded with tourists. Even if the monsters ignored the mortals, that noxious gas couldn’t be good for anyone to breathe. The bigger the monster herd got, the more mortals would get pushed aside, knocked into the water, or trampled.

Finally Frank saw something that would work. Just ahead, past a big piazza, a wooden bridge spanned one of the widest canals. The bridge itself was a latticed arc of timber, like an old-fashioned roller coaster, about fifty meters long.

From above, in eagle form, Frank saw no monsters on the far side. Every katobleps in Venice seemed to have joined the herd and was pushing through the streets behind him as tourists screamed and scattered, maybe thinking they were caught in the midst of a stray dog stampede.

The bridge was empty of foot traffic. It was perfect.

Frank dropped like a stone and turned back to human form. He ran to the middle of the bridge—a natural choke point—and threw his bait of poisonous roots on the deck behind him.

As the front of the katobleps herd reached the base of the bridge, Frank drew Hazel’s golden spatha.

“Come on!” he yelled. “You want to know what Frank Zhang is worth? Come on!”

He realized he wasn’t just shouting at the monsters. He was venting weeks of fear, rage, and resentment. The voices of Mars and Ares screamed right along with him.

The monsters charged. Frank’s vision turned red.

Later, he couldn’t remember the details clearly. He sliced through monsters until he was ankle-deep in yellow dust. Whenever he got overwhelmed and the clouds of gas began to choke him, he changed shape—became an elephant, a dragon, a lion—and each transformation seemed to clear his lungs, giving him a fresh burst of energy. His shape-shifting became so fluid, he could start an attack in human form with his sword and finish as a lion, raking his claws across a katobleps’s snout.

The monsters kicked with their hooves. They breathed noxious gas and glared straight at Frank with their poisonous eyes. He should have died. He should have been trampled. But somehow, he stayed on his feet, unharmed, and unleashed a hurricane of violence.

He didn’t feel any sort of pleasure in this, but he didn’t hesitate, either. He stabbed one monster and beheaded another. He turned into a dragon and bit a katobleps in half, then changed into an elephant and trampled three at once under his feet. His vision was still tinted red, and he realized his eyes weren’t playing tricks on him. He was actually glowing—surrounded by a rosy aura.

He didn’t understand why, but he kept fighting until there was only one monster left.

Frank faced it with his sword drawn. He was out of breath, sweaty, and caked in monster dust, but he was unharmed.

The katobleps snarled. It must not have been the smartest monster. Despite the fact that several hundred of its brethren had just died, it did not back down.

“Mars!” Frank yelled. “I’ve proven myself. Now I need a snake!”

Frank doubted anyone had ever shouted those words before. It was kind of a weird request. He got no answer from the skies. For once, the voices in his head were silent.

The katobleps lost patience. It launched itself at Frank and left him no choice. He slashed upward. As soon as his blade hit the monster, the katobleps disappeared in a flash of blood-red light. When Frank’s vision cleared, a mottled brown Burmese python was coiled at his feet.

“Well done,” said a familiar voice.

Standing a few feet away was his dad, Mars, wearing a red beret and olive fatigues with the insignia of the Italian Special Forces, an assault rifle slung over his shoulder. His face was hard and angular, his eyes covered with dark sunglasses.

“Father,” Frank managed.

He couldn’t believe what he’d just done. The terror started to catch up to him. He felt like sobbing, but he guessed that would not be a good idea in front of Mars.

“It’s natural to feel fear.” The war god’s voice was surprisingly warm, full of pride. “All great warriors are afraid. Only the stupid and the delusional are not. But you faced your fear, my son. You did what you had to do, like Horatius. This was your bridge, and you defended it.”

“I—” Frank wasn’t sure what to say. “I…I just needed a snake.”

A tiny smile tugged at Mars’s mouth. “Yes. And now you have one. Your bravery has united my forms, Greek and Roman, if only for a moment. Go. Save your friends. But hear me, Frank. Your greatest test is yet to come. When you face the armies of Gaea at Epirus, your leadership—”

Suddenly the god doubled over, clutching his head. His form flickered. His fatigues turned into a toga, then a biker’s jacket and jeans. His rifle changed into a sword and then a rocket launcher.

“Agony!” Mars bellowed. “Go! Hurry!”

Frank didn’t ask questions. Despite his exhaustion, he turned into a giant eagle, snatched up the python in his massive claws, and launched himself into the air.

When he glanced back, a miniature mushroom cloud erupted from the middle of the bridge, rings of fire washing outward, and a pair of voices—Mars and Ares—screamed, “Noooo!”

Frank wasn’t sure what had just happened, but he had no time to think about it. He flew over the city—now completely empty of monsters—and headed for the house of Triptolemus.

“You found one!” the farmer god exclaimed.

Frank ignored him. He stormed into La Casa Nera, dragging the python by its tail like a very strange Santa Claus bag, and dropped it next to the bed.

He knelt at Hazel’s side.

She was still alive—green and shivering, barely breathing, but alive. As for Nico, he was still a corn plant.

“Heal them,” Frank said. “Now.”

Triptolemus crossed his arms. “How do I know the snake will work?”

Frank gritted his teeth. Since the explosion on the bridge, the voices of the war god had gone silent in his head, but he still felt their combined anger churning inside him. He felt physically different, too. Had Triptolemus gotten shorter?

“The snake is a gift from Mars,” Frank growled. “It will work.”

As if on cue, the Burmese python slithered over to the chariot and wrapped itself around the right wheel. The other snake woke up. The two serpents checked each other out, touching noses, then turned their wheels in unison. The chariot inched forward, its wings flapping.

“You see?” Frank said. “Now, heal my friends!”

Triptolemus tapped his chin. “Well, thank you for the snake, but I’m not sure I like your tone, demigod. Perhaps I’ll turn you into—”

Frank was faster. He lunged at Trip and slammed him into the wall, his fingers locked around the god’s throat.

“Think about your next words,” Frank warned, deadly calm. “Or instead of beating my sword into a plowshare, I will beat it into your head.”

Triptolemus gulped. “You know…I think I’ll heal your friends.”

“Swear it on the River Styx.”

“I swear it on the River Styx.”

Frank released him. Triptolemus touched his throat, as if making sure it was still there. He gave Frank a nervous smile, edged around him, and scurried off to the front room. “Just—just gathering herbs!”

Frank watched as the god picked leaves and roots and crushed them in a mortar. He rolled a pill-sized ball of green goop and jogged to Hazel’s side. He placed the gunk ball under Hazel’s tongue.

Instantly, she shuddered and sat up, coughing. Her eyes flew open. The greenish tint in her skin disappeared.

She looked around, bewildered, until she saw Frank. “What—?”

Frank tackled her in a hug. “You’re going to be fine,” he said fiercely. “Everything is fine.”

“But…” Hazel gripped his shoulders and stared at him in amazement. “Frank, what happened to you?”

“To me?” He stood, suddenly self-conscious. “I don’t…”

He looked down and realized what she meant. Triptolemus hadn’t gotten shorter. Frank was taller. His gut had shrunk. His chest seemed bulkier.

Frank had had growth spurts before. Once he’d woken up two centimeters taller than when he’d gone to sleep. But this was nuts. It was as if some of the dragon and lion had stayed with him when he’d turned back to human.

“Uh…I don’t…Maybe I can fix it.”

Hazel laughed with delight. “Why? You look amazing!”

“I—I do?”

“I mean, you were handsome before! But you look older, and taller, and so distinguished—”

Triptolemus heaved a dramatic sigh. “Yes, obviously some sort of blessing from Mars. Congratulations, blah, blah, blah. Now, if we’re done here…?”

Frank glared at him. “We’re not done. Heal Nico.”

The farm god rolled his eyes. He pointed at the corn plant, and BAM! Nico di Angelo appeared in an explosion of corn silk.

Nico looked around in a panic. “I—I had the weirdest nightmare about popcorn.” He frowned at Frank. “Why are you taller?”

“Everything’s fine,” Frank promised. “Triptolemus was about to tell us how to survive the House of Hades. Weren’t you, Trip?”

The farm god raised his eyes to the ceiling, like, Why me, Demeter?

“Fine,” Trip said. “When you arrive at Epirus, you will be offered a chalice to drink from.”

“Offered by whom?” Nico asked.

“Doesn’t matter,” Trip snapped. “Just know that it is filled with deadly poison.”

Hazel shuddered. “So you’re saying that we shouldn’t drink it.”

“No!” Trip said. “You must drink it, or you’ll never be able to make it through the temple. The poison connects you to the world of the dead, lets you pass into the lower levels. The secret to surviving is”—his eyes twinkled—“barley.”

Frank stared at him. “Barley.”

“In the front room, take some of my special barley. Make it into little cakes. Eat these before you step into the House of Hades. The barley will absorb the worst of the poison, so it will affect you, but not kill you.”

“That’s it?” Nico demanded. “Hecate sent us halfway across Italy so you could tell us to eat barley?”

“Good luck!” Triptolemus sprinted across the room and hopped in his chariot. “And, Frank Zhang, I forgive you! You’ve got spunk. If you ever change your mind, my offer is open. I’d love to see you get a degree in farming!”

“Yeah,” Frank muttered. “Thanks.”

The god pulled a lever on his chariot. The snake-wheels turned. The wings flapped. At the back of the room, the garage doors rolled open.

“Oh, to be mobile again!” Trip cried. “So many ignorant lands in need of my knowledge. I will teach them the glories of tilling, irrigation, fertilizing!” The chariot lifted off and zipped out of the house, Triptolemus shouting to the sky, “Away, my serpents! Away!”

“That,” Hazel said, “was very strange.”

“The glories of fertilizing.” Nico brushed some corn silk off his shoulder. “Can we get out of here now?”

Hazel put her hand on Frank’s shoulder. “Are you okay, really? You bartered for our lives. What did Triptolemus make you do?”

Frank tried to hold it together. He scolded himself for feeling so weak. He could face an army of monsters, but as soon as Hazel showed him kindness, he wanted to break down and cry. “Those cow monsters…the katoblepones that poisoned you…I had to destroy them.”

“That was brave,” Nico said. “There must have been, what, six or seven left in that herd.”

“No.” Frank cleared his throat. “All of them. I killed all of them in the city.”

Nico and Hazel stared at him in stunned silence. Frank was afraid they might doubt him, or start to laugh. How many monsters had he killed on that bridge—two hundred? Three hundred?

But he saw in their eyes that they believed him. They were children of the Underworld. Maybe they could sense the death and carnage he’d unleashed.

Hazel kissed his cheek. She had to stand on her tiptoes to do it now. Her eyes were incredibly sad, as if she realized something had changed in Frank—something much more important than the physical growth spurt.

Frank knew it too. He would never be the same. He just wasn’t sure if that was a good thing.

“Well,” Nico said, breaking the tension, “does anyone know what barley looks like?”
