The Mark of Athena

The crew compared notes on what had happened in Salt Lake City, but even Leo’s ridiculous story about how he tricked Narcissus wasn’t enough to cheer up the group.

“So where to now?” Leo asked with a mouthful of pizza. “I did a quick repair job to get us out of the lake, but there’s still a lot of damage. We should really put down again and fix things right before we head across the Atlantic.”

Percy was eating a piece of pie, which for some reason was completely blue—filling, crust, even the whipped cream. “We need to put some distance between us and Camp Jupiter,” he said. “Frank spotted some eagles over Salt Lake City. We figure the Romans aren’t far behind us.”

That didn’t improve the mood around the table. Piper didn’t want to say anything, but she felt obliged…and a little guilty. “I don’t suppose we should go back and try to reason with the Romans? Maybe—maybe I didn’t try hard enough with the charmspeak.”

Jason took her hand. “It wasn’t your fault, Pipes. Or Leo’s,” he added quickly. “Whatever happened, it was Gaea’s doing, to drive the two camps apart.”

Piper was grateful for his support, but she still felt uneasy. “Maybe if we could explain that, though—”

“With no proof?” Annabeth asked. “And no idea what really happened? I appreciate what you’re saying, Piper. I don’t want the Romans on our bad side, but until we understand what Gaea’s up to, going back is suicide.”

“She’s right,” Hazel said. She still looked a little queasy from seasickness, but she was trying to eat a few saltine crackers. The rim of her plate was embedded with rubies, and Piper was pretty sure they hadn’t been there at the beginning of the meal. “Reyna might listen, but Octavian won’t. The Romans have honor to think about. They’ve been attacked. They’ll shoot first and ask questions post hac.”

Piper stared at her own dinner. The magical plates could conjure up a great selection of vegetarian stuff. She especially liked the avocado and grilled pepper quesadilla, but tonight she didn’t have much of an appetite.

She thought about the visions she’d seen in her knife: Jason with golden eyes; the bull with the human head; the two giants in yellow togas hoisting a bronze jar from a pit. Worst of all, she remembered herself drowning in black water.

Piper had always liked the water. She had good memories of surfing with her dad. But since she’d started seeing that vision in Katoptris, she’d been thinking more and more of an old Cherokee story her granddad used to tell to keep her away from the river near his cabin. He told her the Cherokees believed in good water spirits, like the naiads of the Greeks; but they also believed in evil water spirits, the water cannibals, who hunted mortals with invisible arrows and were especially fond of drowning small children.

“You’re right,” she decided. “We have to keep going. Not just because of the Romans. We have to hurry.”

Hazel nodded. “Nemesis said we have only six days until Nico dies and Rome is destroyed.”

Jason frowned. “You mean Rome Rome, not New Rome?”

“I think,” Hazel said. “But if so, that’s not much time.”

“Why six days?” Percy wondered. “And how are they going to destroy Rome?”

No one answered. Piper didn’t want to add further bad news, but she felt she had to.

“There’s more,” she said. “I’ve been seeing some things in my knife.”

The big kid, Frank, froze with a forkful of spaghetti halfway to his mouth. “Things such as… ?”

“They don’t really make sense,” Piper said, “just garbled images, but I saw two giants, dressed alike. Maybe twins.”

Annabeth stared at the magical video feed from Camp Half-Blood on the wall. Right now it showed the living room in the Big House: a cozy fire on the hearth and Seymour, the stuffed leopard head, snoring contentedly above the mantel.

“Twins, like in Ella’s prophecy,” Annabeth said. “If we could figure out those lines, it might help.”

“Wisdom’s daughter walks alone,” Percy said. “The Mark of Athena burns through Rome. Annabeth, that’s got to mean you. Juno told me…well, she said you had a hard task ahead of you in Rome. She said she doubted you could do it. But I know she’s wrong.”

Annabeth took a long breath. “Reyna was about to tell me something right before the ship fired on us. She said there was an old legend among the Roman praetors—something that had to do with Athena. She said it might be the reason Greeks and Romans could never get along.”

Leo and Hazel exchanged nervous looks.

“Nemesis mentioned something similar,” Leo said. “She talked about an old score that had to be settled —”

“The one thing that might bring the gods’ two natures into harmony,” Hazel recalled. “‘An old wrong finally avenged.’”

Percy drew a frowny face in his blue whipped cream. “I was only a praetor for about two hours. Jason, you ever hear a legend like that?”

Jason was still holding Piper’s hand. His fingers had turned clammy.

“I…uh, I’m not sure,” he said. “I’ll give it some thought.”

Percy narrowed his eyes. “You’re not sure?”

Jason didn’t respond. Piper wanted to ask him what was wrong. She could tell he didn’t want to discuss this old legend. She caught his eye, and he pleaded silently, Later.

Hazel broke the silence. “What about the other lines?” She turned her ruby-encrusted plate. “Twins snuff out the angel’s breath, Who holds the key to endless death.”

“Giants’ bane stands gold and pale,” Frank added, “Won through pain
