Above them, the ship’s bell rang for dinner.

Jason smirked. “We’d better get up there. We don’t want Coach Hedge tying bells around our necks.”

Piper shuddered. Coach Hedge had threatened to do that after the Percy/Annabeth scandal, so he’d know if anyone sneaked out at night.

“Yeah,” she said regretfully, looking at the glass doors below their feet. “I guess we need dinner…and a good night’s sleep.”

Chapter 26

The next morning Piper woke to a different ship’s horn—a blast so loud it literally shook her out of bed.

She wondered if Leo was pulling another joke. Then the horn boomed again. It sounded like it was coming from several hundred yards away—from another vessel.

She rushed to get dressed. By the time she got up on deck, the others had already gathered—all hastily dressed except for Coach Hedge, who had pulled the night watch.

Frank’s Vancouver Winter Olympics shirt was inside out. Percy wore pajama pants and a bronze breastplate, which was an interesting fashion statement. Hazel’s hair was all blown to one side, as though she’d walked through a cyclone; and Leo had accidentally set himself on fire. His T-shirt was in charred tatters. His arms were smoking.

About a hundred yards to port, a massive cruise ship glided past. Tourists waved at them from fifteen or sixteen rows of balconies. Some smiled and took pictures. None of them looked surprised to see an Ancient Greek trireme. Maybe the Mist made it look like a fishing boat, or perhaps the cruisers thought the Argo II was a tourist attraction.

The cruise ship blew its horn again, and the Argo II had a shaking fit.

Coach Hedge plugged his ears. “Do they have to be so loud?”

“They’re just saying hi,” Frank speculated.

“WHAT?” Hedge yelled back.

The ship edged past them, heading out to sea. The tourists kept waving. If they found it strange that the Argo II was populated by half-asleep kids in armor and pajamas and a man with goat legs, they didn’t let on.

“Bye!” Leo called, raising his smoking hand.

“Can I man the ballistae?” Hedge asked.

“No,” Leo said through a forced smile.

Hazel rubbed her eyes and looked across the glittering green water. “Where are—oh…Wow.”

Piper followed her gaze and gasped. Without the cruise ship blocking their view, she saw a mountain jutting from the sea less than half a mile to the north. Piper had seen impressive cliffs before. She’d driven Highway 1 along the California coast. She’d even fallen down the Grand Canyon with Jason and flown back up. But neither was as amazing as this massive fist of blinding white rock thrust into the sky. On one side, the limestone cliffs were almost completely sheer, dropping into the sea over a thousand feet below, as near as Piper could figure. On the other side, the mountain sloped in tiers, covered in green forest, so that the whole thing reminded Piper of a colossal sphinx, worn down over the millennia, with a massive white head and chest, and a green cloak over its back.

“The Rock of Gibraltar,” Annabeth said in awe. “At the tip of Spain. And over there—” She pointed south, to a more distant stretch of red and ochre hills. “That must be Africa. We’re at the mouth of the Mediterranean.”

The morning was warm, but Piper shivered. Despite the wide stretch of sea in front of them, she felt like she was standing at an impassable barrier. Once in the Mediterranean—the Mare Nostrum—they would be in the ancient lands. If the legends were true, their quest would become ten times more dangerous.

“What now?” she asked. “Do we just sail in?”

“Why not?” Leo said. “It’s a big shipping channel. Boats go in and out all the time.”

Not triremes full of demigods, Piper thought.

Annabeth gazed at the Rock of Gibraltar. Piper recognized that brooding expression on her friend’s face. It almost always meant that she anticipated trouble.

“In the old days,” Annabeth said, “they called this area the pillars of Hercules. The Rock was supposed to be one pillar. The other was one of the African mountains. Nobody is sure which one.”

“Hercules, huh?” Percy frowned. “That guy was like the Starbucks of Ancient Greece. Everywhere you turn—there he is.”

A thunderous boom shook the Argo II, though Piper wasn’t sure where it came from this time. She didn’t see any other ships, and the skies were clear.

Her mouth suddenly felt dry. “So…these Pillars of Hercules. Are they dangerous?”

Annabeth stayed focused on the white cliffs, as if waiting for the Mark of Athena to blaze to life. “For Greeks, the pillars marked the end of the known world. The Romans said the pillars were inscribed with a Latin warning—”

“Non plus ultra,” Percy said.

Annabeth looked stunned. “Yeah. Nothing Further Beyond. How did you know?”

Percy pointed. “Because I’m looking at it.”

Directly ahead of them, in the middle of the straits, an island had shimmered into existence. Piper was positive no island had been there before. It was a small hilly mass of land, covered in forests and ringed with white beaches. Not very impressive compared to Gibraltar, but in front of the island, jutting from waves about a hundred yards offshore, were two white Grecian columns as tall as the Argo’s masts. Between the columns, huge silver words glittered underwater—maybe an illusion, or maybe inlaid in the sand: NON PLUS ULTRA.

“Guys, do I turn around?” Leo asked nervously. “Or…”

No one answered—maybe because, like Piper, they had noticed the figure standing on the beach. As the ship approached the columns, she saw a dark-haired man in purple robes, his arms crossed, staring intently at their ship as if he were expecting them. Piper couldn’t tell much else about him from this distance, but judging from his posture, he wasn’t happy.

Frank inhaled sharply. “Could that be—?”

“Hercules,” Jason said. “The most powerful demigod of all time.”

The Argo II was only a few hundred yards from the columns now.

“Need an answer,” Leo said urgently. “I can turn, or we can take off. The stabilizers are working again. But I need to know quick—”

“We have to keep going,” Annabeth said. “I think he’s guarding these straits. If that’s really Hercules, sailing or flying away wouldn’t do any good. He’ll want to talk to us.”

Piper resisted the urge to use charmspeak. She wanted to yell at Leo: Fly! Get us out of here! Unfortunately, she had a feeling that Annabeth was right. If they wanted to pass into the Mediterranean, they couldn’t avoid this meeting.

“Won’t Hercules be on our side?” she asked hopefully. “I mean…he’s one of us, right?”

Jason grunted. “He was a son of Zeus, but when he died, he became a god. You can never be sure with gods.”

Piper remembered their meeting with Bacchus in Kansas—another god who used to be a demigod. He hadn’t been exactly helpful.

“Great,” Percy said. “Seven of us against Hercules.”

“And a satyr!” Hedge added. “We can take him.”

“I’ve got a better idea,” Annabeth said. “We send ambassadors ashore. A small group—one or two at most. Try to talk with him.”

“I’ll go,” Jason said. “He’s a son of Zeus. I’m the son of Jupiter. Maybe he’ll be friendly to me.”

“Or maybe he’ll hate you,” Percy suggested. “Half brothers don’t always get along.”

Jason scowled. “Thank you, Mr. Optimism.”

“It’s worth a shot,” Annabeth said. “At least Jason and Hercules have something in common. And we need our best diplomat. Somebody who’s good with words.”

All eyes turned to Piper.

She tried to avoid screaming and jumping over the side. A bad premonition gnawed at her gut. But if Jason was going ashore, she wanted to be with him. Maybe this hugely powerful god would turn out to be helpful. They had to have good luck once in a while, didn’t they?

“Fine,” she said. “Just let me change my clothes.”

Once Leo had anchored the Argo II between the pillars, Jason summoned the wind to carry him and Piper ashore.

The man in purple was waiting for them.

Piper had heard tons of stories about Hercules. She’d seen several cheesy movies and cartoons. Before today, if she had thought about him at all, she’d just roll her eyes and imagine some stupid hairy dude in his thirties with a barrel chest and a gross hippie beard, with a lion skin over his head and a big club, like a caveman. She imagined he would smell bad, belch, and scratch himself a lot, and speak mostly in grunts.

She was not expecting this.

His feet were bare, covered in white sand. His robes made him look like a priest, though Piper couldn’t remember which rank of priest wore purple. Was that cardinals? Bishops? And did the purple color mean he was the Roman version of Hercules rather than the Greek? His beard was fashionably scruffy, like Piper’s dad and his actor friends wore theirs—the sort of I just happened not to shave for two days and I still look awesome look.

He was well built, but not too stocky. His ebony hair was close-cropped, Roman style. He had startling blue eyes like Jason’s, but his skin was coppery, as if he’d spent his entire life on a tanning bed. The most surprising thing: he looked about twenty. Definitely no older. He was handsome in a rugged but not-at-all-caveman way.

He did in fact have a club, which lay in the sand next to him, but it was more like an oversized baseball bat—a five-foot-long polished cylinder of mahogany with a leather handgrip studded in bronze. Coach Hedge would have been jealous.

Jason and Piper landed at the edge of the surf. They approached slowly, careful not to make any threatening moves. Hercules watched them with no particular emotion, as if they were some form of seabird he had never noticed before.

“Hello,” Piper said. Always a good start.

“What’s up?” Hercules said. His voice was deep but casual, very modern. He could’ve been greeting them in the high school locker room.

“Uh, not much.” Piper winced. “Well, actually, a lot. I’m Piper. This is Jason. We—”

“Where’s your lion skin?” Jason interrupted.

Piper wanted to elbow him, but Hercules looked more amused than annoyed.

“It’s ninety degrees out here,” he said. “Why would I wear my lion skin? Do you wear a fur coat to the beach?”

“I guess that makes sense.” Jason sounded disappointed. “It’s just that the pictures always show you with a lion skin.”

Hercules glared at the sky accusingly, like he wanted to have words with his father, Zeus. “Don’t believe everything you hear about me. Being famous isn’t as fun as you might think.”

“Tell me about it,” Piper sighed.

Hercules fixed those brilliant blue eyes on her. “Are you famous?”

“My dad…he’s in the movies.”
