The House of Hades (The Heroes of Olympus 4)

JASON FIRST SAW THE ANGEL AT THE ICE CREAM CART.

The Argo II had anchored in the bay along with six or seven cruise ships. As usual, the mortals didn’t pay the trireme any attention; but just to be safe, Jason and Nico hopped on a skiff from one of the tourist boats so they would look like part of the crowd when they came ashore.

At first glance, Split seemed like a cool place. Curving around the harbor was a long esplanade lined with palm trees. At the sidewalk cafés, European teenagers were hanging out, speaking a dozen different languages and enjoying the sunny afternoon. The air smelled of grilled meat and fresh-cut flowers.

Beyond the main boulevard, the city was a hodgepodge of medieval castle towers, Roman walls, limestone town houses with red-tiled roofs, and modern office buildings all crammed together. In the distance, gray-green hills marched toward a mountain ridge, which made Jason a little nervous. He kept glancing at that rocky escarpment, expecting the face of Gaea to appear in its shadows.

Nico and he were wandering along the esplanade when Jason spotted the guy with wings buying an ice cream bar from a street cart. The vendor lady looked bored as she counted the guy’s change. Tourists navigated around the angel’s huge wings without a second glance.

Jason nudged Nico. “Are you seeing this?”

“Yeah,” Nico agreed. “Maybe we should buy some ice cream. ”

As they made their way toward the street cart, Jason worried that this winged dude might be a son of Boreas the North Wind. At his side, the angel carried the same kind of jagged bronze sword the Boreads had, and Jason’s last encounter with them hadn’t gone so well.

But this guy seemed more chill than chilly. He wore a red tank top, Bermuda shorts, and huarache sandals. His wings were a combination of russet colors, like a bantam rooster or a lazy sunset. He had a deep tan and black hair almost as curly as Leo’s.

“He’s not a returned spirit,” Nico murmured. “Or a creature of the Underworld. ”

“No,” Jason agreed. “I doubt they would eat chocolate-covered ice cream bars. ”

“So what is he?” Nico wondered.

They got within thirty feet, and the winged dude looked directly at them. He smiled, gestured over his shoulder with his ice cream bar, and dissolved into the air.

Jason couldn’t exactly see him, but he’d had enough experience controlling the wind that he could track the angel’s path—a warm wisp of red and gold zipping across the street, spiraling down the sidewalk, and blowing postcards from the carousels in front of the tourist shops. The wind headed toward the end of the promenade, where a big fortresslike structure loomed.

“I’m betting that’s the palace,” Jason said. “Come on. ”

Even after two millennia, Diocletian’s Palace was still impressive. The outer wall was only a pink granite shell, with crumbling columns and arched windows open to the sky, but it was mostly intact, a quarter mile long and seventy or eighty feet tall, dwarfing the modern shops and houses that huddled beneath it. Jason imagined what the palace must have looked like when it was newly built, with Imperial guards walking the ramparts and the golden eagles of Rome glinting on the parapets.

The wind angel—or whatever he was—whisked in and out of the pink granite windows, then disappeared on the other side. Jason scanned the palace’s facade for an entrance. The only one he saw was several blocks away, with tourists lined up to buy tickets. No time for that.

“We’ve got to catch him,” Jason said. “Hold on. ”

“But—”

Jason grabbed Nico and lifted them both into the air.

Nico made a muffled sound of protest as they soared over the walls and into a courtyard where more tourists were milling around, taking pictures.

A little kid did a double take when they landed. Then his eyes glazed over and he shook his head, like he was dismissing a juice-box-induced hallucination. No one else paid them any attention.

On the left side of the courtyard stood a line of columns holding up weathered gray arches. On the right side was a white marble building with rows of tall windows.

“The peristyle,” Nico said. “This was the entrance to Diocletian’s private residence. ” He scowled at Jason. “And please, I don’t like being touched. Don’t ever grab me again. ”

Jason’s shoulder blades tensed. He thought he heard the undertone of a threat, like: unless you want to get a Stygian sword up your nose. “Uh, okay. Sorry. How do you know what this place is called?”

Nico scanned the atrium. He focused on some steps in the far corner, leading down.

“I’ve been here before. ” His eyes were as dark as his blade. “With my mother and Bianca. A weekend trip from Venice. I was maybe…six?”

“That was when…the 1930s?”

“’Thirty-eight or so,” Nico said absently. “Why do you care? Do you see that winged guy anywhere?”

“No…” Jason was still trying to wrap his mind around Nico’s past.

Jason always tried to build a good relationship with the people on his team. He’d learned the hard way that if somebody was going to have your back in a fight, it was better if you found some common ground and trusted each other. But Nico wasn’t easy to figure out. “I just…I can’t imagine how weird that must be, coming from another time. ”

“No, you can’t. ” Nico stared at the stone floor. He took a deep breath.

“Look…I don’t like talking about it. Honestly, I think Hazel has it worse. She remembers more about when she was young. She had to come back from the dead and adjust to the modern world. Me…me and Bianca, we were stuck at the Lotus Hotel. Time passed so quickly. In a weird way, that made the transition easier. ”

“Percy told me about that place,” Jason said. “Seventy years, but it only felt like a month?”

Nico clenched his fist until his fingers turned white. “Yeah. I’m sure Percy told you all about me. ”
