asked.
“Mare Nostrum,” Jason explained. “ Our Sea. It’s what the Ancient Romans called the Mediterranean.”
Reyna nodded. “The territory that was once the Roman Empire is not only the birthplace of the gods. It’s also the ancestral home of the monsters, Titans and giants…and worse things. As dangerous as travel is for demigods here in America, there it would be ten times worse.”
“You said Alaska would be bad,” Percy reminded her. “We survived that.”
Reyna shook her head. Her fingernails cut little crescents into the apple as she turned it. “Percy, traveling in the Mediterranean is a different level of danger altogether. It’s been off limits to Roman demigods for centuries. No hero in his right mind would go there.”
“Then we’re good!” Leo grinned over the top of his pinwheel. “Because we’re all crazy, right? Besides, the Argo II is a top-of-the-line warship. She’ll get us through.”
“We’ll have to hurry,” Jason added. “I don’t know exactly what the giants are planning, but Gaea is growing more conscious all the time. She’s invading dreams, appearing in weird places, summoning more and more powerful monsters. We have to stop the giants before they can wake her up fully.”
Annabeth shuddered. She’d had her own share of nightmares lately.
“Seven half-bloods must answer the call,” she said. “It needs to be a mix from both our camps. Jason, Piper, Leo, and me. That’s four.”
“And me,” Percy said. “Along with Hazel and Frank. That’s seven.”
“What?” Octavian shot to his feet. “We’re just supposed to accept that? Without a vote in the senate? Without a proper debate? Without—”
“Percy!” Tyson the Cyclops bounded toward them with Mrs. O’Leary at his heels. On the hellhound’s back sat the skinniest harpy Annabeth had ever seen—a sickly-looking girl with stringy red hair, a sackcloth dress, and red-feathered wings.
Annabeth didn’t know where the harpy had come from, but her heart warmed to see Tyson in his tattered flannel and denim with the backward SPQR banner across his chest. She’d had some pretty bad experiences with Cyclopes, but Tyson was a sweetheart. He was also Percy’s half brother (long story), which made him almost like family.
Tyson stopped by their couch and wrung his meaty hands. His big brown eye was full of concern. “Ella is scared,” he said.
“N-n-no more boats,” the harpy muttered to herself, picking furiously at her feathers. “ Titanic , Lusitania , Pax …boats are not for harpies.”
Leo squinted. He looked at Hazel, who was seated next to him. “Did that chicken girl just compare my ship to the Titanic ?”
“She’s not a chicken.” Hazel averted her eyes, as if Leo made her nervous. “Ella’s a harpy. She’s just a little…high-strung.”
“Ella is pretty,” Tyson said. “And scared. We need to take her away, but she will not go on the ship.”
“No ships,” Ella repeated. She looked straight at Annabeth. “Bad luck. There she is. Wisdom’s daughter walks alone—”
“Ella!” Frank stood suddenly. “Maybe it’s not the best time—”
“The Mark of Athena burns through Rome,” Ella continued, cupping her hands over her ears and raising her voice. “Twins snuff out the angel’s breath, Who holds the key to endless death. Giants’ bane stands gold and pale, Won through pain from a woven jail.”
The effect was like someone dropping a flash grenade on the table. Everyone stared at the harpy. No one spoke. Annabeth’s heart was pounding. The Mark of Athena… She resisted the urge to check her pocket, but she could feel the silver coin growing warmer—the cursed gift from her mother. Follow the Mark of Athena. Avenge me.
Around them, the sounds of the feast continued, but muted and distant, as if their little cluster of couches had slipped into a quieter dimension.
Percy was the first to recover. He stood and took Tyson’s arm.
“I know!” he said with
