The Mark of Athena

“Excellent.” Ephialtes rubbed his hands together in anticipation. “This is our big chance, my brother.”

“That’s what you said about our last stunt,” Otis mumbled. “I was hanging in that block of ice suspended over the River Lethe for six months, and we didn’t even get any media attention.”

“This is different!” Ephialtes insisted. “We will set a new standard for entertainment! If Mother is pleased, we can write our own ticket to fame and fortune!”

“If you say so,” Otis sighed. “Though I still think those ballerina costumes from Swan Lake would look lovely—”

“No ballet!”

“Sorry.”

“Come,” Ephialtes said. “Let’s examine the tigers. I want to be sure they are hungry!”

The giants lumbered off into the gloom, and Percy turned toward the jar.

I need to see inside, he thought.

He willed his dream forward, right to the surface of the jar. Then he passed through.

The air in the jar smelled of stale breath and tarnished metal. The only light came from the dim purple glow of a dark sword, its Stygian iron blade set against one side of the container. Huddled next to it was a dejected-looking boy in tattered jeans, a black shirt, and an old aviator jacket. On his right hand, a silver skull ring glittered.

“Nico,” Percy called. But the son of Hades couldn’t hear him.

The container was completely sealed. The air was turning poisonous. Nico’s eyes were closed, his breathing shallow. He appeared to be meditating. His face was pale, and thinner than Percy remembered.

On the inner wall of the jar, it looked as though Nico had scratched three hash marks with his sword—maybe it had been three days that he’d been imprisoned?

It didn’t seem possible he could have survived so long without suffocating. Even in a dream, Percy was already starting to feel panicky, struggling to get enough oxygen.

Then he noticed something between Nico’s feet—a small collection of glistening objects no bigger than baby teeth.

Seeds, Percy realized. Pomegranate seeds. Three had been eaten and spit out. Five were still encased in dark red pulp.

“Nico,” Percy said, “where is this place? We’ll save you.…”

The image faded, and a girl’s voice whispered: “Percy.”

At first, Percy thought he was still asleep. When he’d lost his memory, he’d spent weeks dreaming about Annabeth, the only person he remembered from his past. As his eyes opened and his vision cleared, he realized she was really there.

She was standing by his berth, smiling down at him.

Her blond hair fell across her shoulders. Her storm-gray eyes were bright with amusement. He remembered his first day at Camp Half-Blood, five years ago, when he’d woken from a daze and found Annabeth standing over him. She had said, You drool when you sleep.

She was sentimental that way.

“Wh—what’s going on?” he asked. “Are we there?”

“No,” she said, her voice low. “It’s the middle of the night.”

“You mean…” Percy’s heart started to race. He realized he was in his pajamas, in bed. He probably had been drooling, or at least making weird noises as he dreamed. No doubt he had a severe case of pillow hair and his breath didn’t smell great. “You sneaked into my cabin?”

Annabeth rolled her eyes. “Percy, you’ll be seventeen in two months. You can’t seriously be worried about getting into trouble with Coach Hedge.”

“Uh, have you seen his baseball bat?”

“Besides, Seaweed Brain, I just thought we could take a walk. We haven’t had any time to be together alone. I want to show you something—my favorite place aboard the ship.”

Percy’s pulse was still in overdrive, but it wasn’t from fear of getting into trouble. “Can I, you know, brush my teeth first?”

“You’d better,” Annabeth said. “Because I’m not kissing you until you do. And brush your hair while you’re at it.”

For a trireme, the ship was huge, but it still felt cozy to Percy—like his dorm building back at Yancy Academy, or any of the other boarding schools he’d gotten kicked out of. Annabeth and he crept downstairs to the second deck, which Percy hadn’t explored except for sickbay.

She led him past the engine room, which looked like a very dangerous, mechanized jungle gym, with pipes and pistons and tubes jutting from a central bronze sphere. Cables resembling giant metal noodles snaked across the floor and ran up the walls.

“How does that thing even work?” Percy asked.

“No idea,” Annabeth said. “And I’m the only one besides Leo who can operate it.”

“That’s reassuring.”

“It should be fine. It’s only threatened to blow up once.”

“You’re kidding, I hope.”
