The Lost Hero

“What?” Jason asked.

Thalia shook her head. “I’ll have to talk to the goddess. Maybe Artemis will guide us.”

“She’s still talking to you?” Jason asked. “Most of the gods have gone silent.”

“Artemis follows her own rules,” Thalia said. “She has to be careful not to let Zeus know, but she thinks Zeus is being ridiculous closing Olympus. She’s the one who set us on the trail of Lycaon. She said we’d find a lead to a missing friend of ours.”

“Percy Jackson,” Leo guessed. “The guy Annabeth is looking for.”

Thalia nodded, her face full of concern.

Leo wondered if anyone had ever looked that worried all the times he’d disappeared. He kind of doubted it.

“So what would Lycaon have to do with it?” Leo asked. “And how does it connect to us?”

“We need to find out soon,” Thalia admitted. “If your deadline is tomorrow, we’re wasting time. Aeolus could tell you—”

The white wolf appeared again at the doorway and yipped insistently.

“I have to get moving.” Thalia stood. “Otherwise I’ll lose the other Hunters’ trail. First, though, I’ll take you to Aeolus’s palace.”

“If you can’t, it’s okay,” Jason said, though he sounded kind of distressed.

“Oh, please.” Thalia smiled and helped him up. “I haven’t had a brother in years. I think I can stand a few minutes with you before you get annoying. Now, let’s go!”

XXXVI LEO

WHEN LEO SAW HOW WELL PIPER AND HEDGE were being treated, he was thoroughly offended.

He’d imagined them freezing their hindquarters off in the snow, but the Hunter Phoebe had set up this silver tent pavilion thing right outside the cave. How she’d done it so fast, Leo had no idea, but inside was a kerosene heater keeping them toasty warm and a bunch of comfy throw pillows. Piper looked back to normal, decked out in a new parka, gloves, and camo pants like a Hunter. She and Hedge and Phoebe were kicking back, drinking hot chocolate.

“Oh, no way,” Leo said. “We’ve been sitting in a cave and you get the luxury tent? Somebody give me hypothermia. I want hot chocolate and a parka!”

Phoebe sniffed. “Boys,” she said, like it was the worst insult she could think of.

“It’s all right, Phoebe,” Thalia said. “They’ll need extra coats. And I think we can spare some chocolate.”

Phoebe grumbled, but soon Leo and Jason were also dressed in silvery winter clothes that were incredibly lightweight and warm. The hot chocolate was first-rate.

“Cheers!” said Coach Hedge. He crunched down his plastic thermos cup.

“That cannot be good for your intestines,” Leo said.

Thalia patted Piper on the back. “You up for moving?”

Piper nodded. “Thanks to Phoebe, yeah. You guys are really good at this wilderness survival thing. I feel like I could run ten miles.”

Thalia winked at Jason. “She’s tough for a child of Aphrodite. I like this one.”

“Hey, I could run ten miles too,” Leo volunteered. “Tough Hephaestus kid here. Let’s hit it.”

Naturally, Thalia ignored him.

It took Phoebe exactly six seconds to break camp, which Leo could not believe. The tent self-collapsed into a square the size of a pack of chewing gum. Leo wanted to ask her for the blueprints, but they didn’t have time.

Thalia ran uphill through the snow, hugging a tiny little path on the side of the mountain, and soon Leo was regretting trying to look macho, because the Hunters left him in the dust.

Coach Hedge leaped around like a happy mountain goat, coaxing them on like he used to do on track days at school. “Come on, Valdez! Pick up the pace! Let’s chant. I’ve got a girl in Kalamazoo— ”

“Let’s not,” Thalia snapped.

So they ran in silence.

Leo fell in next to Jason at the back of the group. “How you doing, man?”

Jason’s expression was enough of an answer: Not good.

“Thalia takes it so calmly,” Jason said. “Like it’s no big deal that I appeared. I didn’t know what I was expecting, but … she’s not like me. She seems so much more together.”

“Hey, she’s not fighting amnesia,” Leo said. “Plus, she’s had more time to get used to this whole demigod thing. You fight monsters and talk to gods for a while, you probably get used to surprises.”

“Maybe,” Jason said. “I just wish I understood what happened when I was two, why my mom got rid of me. Thalia ran away because of me.”

“Hey, whatever’s happened, it wasn’t your fault. And your sister is pretty cool. She’s a lot like you.”

Jason took that in silence. Leo wondered if he’d said the right things. He wanted to make Jason feel better, but this was way outside his comfort zone.

Leo wished he could reach inside his tool belt and pick just the right wrench to fix Jason’s memory—maybe a little hammer—bonk the sticking spot and make everything run right. That would be a lot easier than trying to talk it through. Not good with organic life forms. Thanks for those inherited traits, Dad.

He was so lost in thought, he didn’t realize the Hunters had stopped. He slammed into Thalia and nearly sent them both down the side of the mountain the hard way. Fortunately, the Hunter was light on her feet. She steadied them both, then pointed up.

“That,” Leo choked, “is a really large rock.”

They stood near the summit of Pikes Peak. Below them the world was blanketed in clouds. The air was so thin, Leo could hardly breathe. Night had set in, but a full moon shone and the stars were incredible. Stretching out to the north and south, peaks of other mountains rose from the clouds like islands—or teeth.

But the real show was above them. Hovering in the sky, about a quarter mile away, was a massive free- floating island of glowing purple stone. It was hard to judge its size, but Leo figured it was at least as wide as a football stadium and just as tall. The sides were rugged cliffs, riddled with caves, and every once in a while a gust of wind burst out with a sound like a pipe organ blast. At the top of the rock, brass walls ringed some kind of a fortress.

The only thing connecting Pikes Peak to the floating island was a narrow bridge of ice that glistened in the moonlight.

Then Leo realized the bridge wasn’t exactly ice, because it wasn’t solid. As the winds changed direction, the bridge snaked around—blurring and thinning, in some places even breaking into a dotted line like the vapor trail of a plane.

“We’re not seriously crossing that,” Leo said.

Thalia shrugged. “I’m not a big fan of heights, I’ll admit. But if you want to get to Aeolus’s fortress, this is the only way.”

“Is the fortress always hanging there?” Piper asked. “How can people not notice it sitting on top of Pikes Peak?”

“The Mist,” Thalia said. “Still, mortals do notice it indirectly. Some days, Pikes Peak looks purple. People say it’s a trick of the light, but actually it’s the color of Aeolus’s palace, reflecting off the mountain face.”

“It’s enormous,” Jason said.

Thalia laughed. “You should see Olympus, little brother.”

“You’re serious? You’ve been there?”

Thalia grimaced as if it wasn’t a good memory. “We should go across in two different groups. The bridge is
