The Mark of Athena (The Heroes of Olympus #3)(37)

They’re my friends, she told herself. It’s okay.

But she had a strange feeling…as if more than six sets of eyes were watching her.

“Today on the highway,” she said, “Gaea told me that she needed the blood of only two demigods—one female, one male. She—she asked me to choose which boy would die.”

Jason squeezed her hand. “But neither of us died. You saved us.”

“I know. It’s just…Why would she want that?”

Leo whistled softly. “Guys, remember at the Wolf House? Our favorite ice princess, Khione? She talked about spilling Jason’s blood, how it would taint the place for generations. Maybe demigod blood has some kind of power.”

“Oh…” Percy set down his third pizza slice. He leaned back and stared at nothing, as if the horse kick to his head had just now registered.

“Percy?” Annabeth gripped his arm.

“Oh, bad,” he muttered. “Bad. Bad.” He looked across the table at Frank and Hazel. “You guys remember Polybotes?”

“The giant who invaded Camp Jupiter,” Hazel said. “The anti-Poseidon you whacked in the head with a Terminus statue. Yes, I think I remember.”

“I had a dream,” Percy said, “when we were flying to Alaska. Polybotes was talking to the gorgons, and he said—he said he wanted me taken prisoner, not killed. He said: ‘I want that one chained at my feet, so I can kill him when the time is ripe. His blood shall water the stones of Mount Olympus and wake Earth Mother!’”

Piper wondered if the room’s temperature controls were broken, because suddenly she couldn’t stop shaking. It was the same way she’d felt on the highway outside Topeka. “You think the giants would use our blood…the blood of two of us—”

“I don’t know,” Percy said. “But until we figure it out, I suggest we all try to avoid getting captured.”

Jason grunted. “That I agree with.”

“But how do we figure it out?” Hazel asked. “The Mark of Athena, the twins, Ella’s prophecy…how does it all fit together?”

Annabeth pressed her hands against the edge of the table. “Piper, you told Leo to set our course for Atlanta.”

“Right,” Piper said. “Bacchus told us we should seek out…what was his name?”

“Phorcys,” Percy said.

Annabeth looked surprised, like she wasn’t used to her boyfriend having the answers. “You know him?”

Percy shrugged. “I didn’t recognize the name at first. Then Bacchus mentioned salt water, and it rang a bell. Phorcys is an old sea god from before my dad’s time. Never met him, but supposedly he’s a son of Gaea. I still don’t understand what a sea god would be doing in Atlanta.”

Leo snorted. “What’s a wine god doing in Kansas? Gods are weird. Anyway, we should reach Atlanta by noon tomorrow, unless something else goes wrong.”

“Don’t even say that,” Annabeth muttered. “It’s getting late. We should all get some sleep.”

“Wait,” Piper said.

Once more, everyone looked at her.

She was rapidly losing her courage, wondering if her instincts were wrong, but she forced herself to speak.

“There’s one last thing,” she said. “The eidolons—the possessing spirits. They’re still here, in this room.”

Chapter 12

Piper couldn’t explain how she knew.

Stories of phantoms and tortured souls had always freaked her out. Her dad used to joke about Grandpa Tom’s Cherokee legends from back on the rez, but even at home in their big Malibu mansion, looking out over the Pacific, whenever her dad recounted the ghost stories for her, she could never get them out of her head.

Cherokee spirits were always restless. They often lost their way to the Land of the Dead, or stayed behind with the living out of sheer stubbornness. Sometimes they didn’t even realize they were dead.

The more Piper learned about being a demigod, the more convinced she was that Cherokee legends and Greek myths weren’t so different. These eidolons acted a lot like the spirits in her dad’s stories.

Piper had a gut sense they were still present, simply because no one had told them to go away.

When she was done explaining, the others looked at her uncomfortably. Up on deck, Hedge sang something that sounded like “In the Navy” while Blackjack stomped his hooves, whinnying in protest.

Finally Hazel exhaled. “Piper is right.”

“How can you be sure?” Annabeth asked.

“I’ve met eidolons,” Hazel said. “In the Underworld, when I was…you know.”

Dead.

Piper had forgotten that Hazel was a second-timer. In her own way, Hazel too was a ghost reborn.

“So…” Frank rubbed his hand across his buzz-cut hair as if some ghosts might have invaded his scalp. “You think these things are lurking on the ship, or—”

“Possibly lurking inside some of us,” Piper said. “We don’t know.”

Jason clenched his fist. “If that’s true—”

“We have to take steps,” Piper said. “I think I can do this.”

“Do what?” Percy asked.

“Just listen, okay?” Piper took a deep breath. “Everybody listen.”
