The Mark of Athena (The Heroes of Olympus #3)(121)

The room was suddenly quiet except for a few random sparks and sizzles. The air smelled like burning car engines. Leo raced down the stairs and found Frank and Hazel safe under their table. He had never been so happy to see those two hugging.

“You’re alive!” he said.

Hazel’s left eye twitched, maybe from the Taser shock. Otherwise she looked okay. “Uh, what exactly happened?”

“Archimedes came through!” Leo said. “Just enough power left in those old machines for one final show. Once I had the access code, it was easy.”

He patted the control sphere, which was steaming in a bad way. Leo didn’t know if it could be fixed, but at the moment he was too relieved to care.

“The eidolons,” Frank said. “Are they gone?”

Leo grinned. “My last command overloaded their kill switches—basically locked down all their circuits and melted their cores.”

“In English?” Frank asked.

“I trapped the eidolons inside the wiring,” Leo said. “Then I melted them. They won’t be bothering anyone again.”

Leo helped his friends to their feet.

“You saved us,” Frank said.

“Don’t sound so surprised.” Leo glanced around the destroyed workshop. “Too bad all this stuff got wrecked, but at least I salvaged the scrolls. If I can get them back to Camp Half-Blood, maybe I can learn how to recreate Archimedes’s inventions.”

Hazel rubbed the side of her head. “But I don’t understand. Where is Nico? That tunnel was supposed to lead us to Nico.”

Leo had almost forgotten why they’d come down here in the first place. Nico obviously wasn’t here. The place was a dead end. So why… ?

“Oh.” He felt like there was a buzz-saw sphere on his own head, pulling out his wires and gears. “Hazel, how exactly were you tracking Nico? I mean, could you just sense him nearby because he was your brother?”

She frowned, still looking a bit wobbly from her electric shock treatment. “Not—not totally. Sometimes I can tell when he’s close, but, like I said, Rome is so confusing, so much interference because of all the tunnels and caves—”

“You tracked him with your metal-finding senses,” Leo guessed. “His sword?”

She blinked. “How did you know?”

“You’d better come here.” He led Hazel and Frank up to the control room and pointed to the black sword.

“Oh. Oh, no.” Hazel would’ve collapsed if Frank hadn’t caught her. “But that’s impossible! Nico’s sword was with him in the bronze jar. Percy saw it in his dream!”

“Either the dream was wrong,” Leo said, “or the giants moved the sword here as a decoy.”

“So this was a trap,” Frank said. “We were lured here.”

“But why?” Hazel cried. “Where’s my brother?”

A hissing sound filled the control booth. At first, Leo thought the eidolons were back. Then he realized the bronze mirror on the table was steaming.

Ah, my poor demigods. The sleeping face of Gaea appeared in the mirror. As usual, she spoke without moving her mouth, which could only have been creepier if she’d had a ventriloquism puppet. Leo hated those things.

You had your choice, Gaea said. Her voice echoed through the room. It seemed to be coming not just from the mirror, but from the stone walls as well.

Leo realized she was all around them. Of course. They were in the earth. They’d gone to all the trouble of building the Argo II so they could travel by sea and air, and they’d ended up in the earth anyway.

I offered salvation to all of you, Gaea said. You could have turned back. Now it is too late. You’ve come to the ancient lands where I am strongest—where I will wake.

Leo pulled a hammer from his tool belt. He whacked the mirror. Being metal, it just quivered like a tea tray, but it felt good to smash Gaea in the nose.

“In case you haven’t noticed, Dirt Face,” he said, “your little ambush failed. Your three eidolons got melted in bronze, and we’re fine.”

Gaea laughed softly. Oh, my sweet Leo. You three have been separated from your friends. That was the whole point.

The workshop door slammed shut.

You are trapped in my embrace, Gaea said. Meanwhile, Annabeth Chase faces her death alone, terrified and crippled, at the hands of her mother’s greatest enemy.

The image in the mirror changed. Leo saw Annabeth sprawled on the floor of a dark cavern, holding up her bronze knife as if warding off a monster. Her face was gaunt. Her leg was wrapped up in some sort of splint. Leo couldn’t see what she was looking at, but it was obviously something horrible. He wanted to believe the image was a lie, but he had a bad feeling it was real, and it was happening right now.

The others, Gaea said, Jason Grace, Piper McLean, and my dear friend Percy Jackson—they will perish within minutes.

The scene changed again. Percy was holding Riptide, leading Jason and Piper down a spiral staircase into the darkness.

Their powers will betray them, Gaea said. They will die in their own elements. I almost hoped they would survive. They would have made a better sacrifice. But alas, Hazel and Frank, you will have to do. My minions will collect you shortly and bring you to the ancient place. Your blood will awaken me at last. Until then, I will allow you to watch your friends perish. Please…enjoy this last glimpse of your failed quest.
