"Getting jumped by the Cyclopes," she said. "It wasn't your fault."

He looked down at the coin in his palm. "I was stupid. I left you alone and walked into a trap. I should've known..."

He didn't finish. There were too many things he should have known-who he was, how to fight monsters, how Cyclopes lured their victims by mimicking voices and hiding in shadows and a hundred other tricks. All that information was supposed to be in his head. He could feel the places it should be-like empty pockets. If Hera wanted him to succeed, why had she stolen the memories that could help him? She claimed his amnesia had kept him alive, but that made no sense. He was starting to understand why Annabeth had wanted to leave the G.o.ddess in her cage.

"Hey." Piper nudged his arm. "Cut yourself some slack. Just because you're the son of Zeus doesn't mean you're a one-man army."

A few feet away, Leo lit a small cooking fire. He hummed as he pulled supplies out of his pack and his tool belt.

In the firelight, Piper's eyes seemed to dance. Jason had been studying them for days now, and he still couldn't decide what color they were.

"I know this must suck for you," he said. "Not just the quest, I mean. The way I appeared on the bus, the Mist messing with your mind, and making you think I was ...you know."

She dropped her gaze. "Yeah, well. None of us asked for this. It's not your fault."

She tugged at the little braids on each side of her head. Again, Jason thought how glad he was that she'd lost the Aphrodite blessing. With the makeup and the dress and the perfect hair, she'd looked about twenty-five, glamorous, and completely out of his league. He'd never thought of beauty as a form of power, but that's the way Piper had seemed-powerful.

He liked regular Piper better-someone he could hang out with. But the weird thing was, he couldn't quite get that other image out of his head. It hadn't been an illusion. That side of Piper was there too. She just did her best to hide it.

"Back in the factory," Jason said, "you were you going to say something about your dad."

She traced her finger over the bricks, almost like she was writing out a scream she didn't want to vocalize. "Was I?"

"Piper," he said, "he's in some kind of trouble, isn't it?"

Over at the fire, Leo stirred some sizzling bell peppers and meat in a pan. "Yeah, baby! Almost there."

Piper looked on the verge of tears. "Jason ... I can't talk about it."

"We're your friends. Let us help."

That seemed to make her feel worse. She took a shaky breath. "I wish I could, but-"

"And bingo!" Leo announced.

He came over with three plates stacked on his arms like a waiter. Jason had no idea where he'd gotten all the food, or how he'd put it together so fast, but it looked amazing: pepper and beef tacos with chips and salsa.

"Leo," Piper said in amazement. "How did you-?"

"Chef Leo's Taco Garage is fixing you up!" he said proudly. "And by the way, it's tofu, not beef, beauty queen, so don't freak. Just dig in!"

Jason wasn't sure about tofu, but the tacos tasted as good as they smelled. While they ate, Leo tried to lighten the mood and joke around. Jason was grateful Leo was with them. It made being with Piper a little less intense and uncomfortable. At the same time, he kind of wished he was alone with her; but he chided himself for feeling that way.

After Piper ate, Jason encouraged her to get some sleep. Without another word, she curled up and put her head in his lap. In two seconds she was snoring.

Jason looked up at Leo, who was obviously trying not to laugh.

They sat in silence for a few minutes, drinking lemonade Leo had made from canteen water and powdered mix.

"Good, huh?" Leo grinned.

"You should start a stand," Jason said. "Make some serious coin."

But as he stared at the embers of the fire, something began to bother him. "Leo ... about this fire stuff you can do ... is it true?"

Leo's smile faltered. "Yeah, well ..." He opened his hand. A small ball of flame burst to life, dancing across his palm.

"That is so cool," Jason said. "Why didn't you say anything?"

Leo closed his hand and the fire went out. "Didn't want to look like a freak."

"I have lightning and wind powers," Jason reminded him. "Piper can turn beautiful and charm people into giving her BMWs. You're no more a freak than we are. And, hey, maybe you can fly, too. Like jump off a building and yell, 'Flame on!'"

Leo snorted. "If I did that, you would see a flaming kid falling to his death, and I would be yelling something a little stronger than 'Flame on!' Trust me, Hephaestus cabin doesn't see fire powers as cool. Nyssa told me they're super rare. When a demiG.o.d like me comes around, bad things happen. Really bad."

"Maybe it's the other way around," Jason suggested. "Maybe people with special gifts show up when bad things are happening because that's when they're needed most."

Leo cleared away the plates. "Maybe. But I'm telling you ... it's not always a gift."

Jason fell silent. "You're talking about your mom, aren't you? The night she died."

Leo didn't answer. He didn't have to. The fact that he was quiet, not joking around-that told Jason enough.

"Leo, her death wasn't your fault. Whatever happened that night-it wasn't because you could summon fire. This Dirt Woman, whoever she is, has been trying to ruin you for years, mess up your confidence, take away everything you care about. She's trying to make you feel like a failure. You're not. You're important."

"That's what she said." Leo looked up, his eyes full of pain. "She said I was meant to do something important-something that would make or break that big prophecy about the seven demiG.o.ds. That's what scares me. I don't know if I'm up to it."

Jason wanted to tell him everything would be all right, but it would've sounded fake. Jason didn't know what would happen. They were demiG.o.ds, which meant sometimes things didn't end okay. Sometimes you got eaten by the Cyclops.

If you asked most kids, "Hey, you want to summon fire or lightning or magical makeup?" they'd think it sounded pretty cool. But those powers went along with hard stuff, like sitting in a sewer in the middle of winter, running from monsters, losing your memory, watching your friends almost get cooked, and having dreams that warned you of your own death.

Leo poked at the remnants of his fire, turning over red-hot coals with his bare hand. "You ever wonder about the other four demiG.o.ds? I mean ... if we're three of the ones from the Great Prophecy, who are the others? Where are they?"

Jason had thought about it, all right, but he tried to push it out of his mind. He had a horrible suspicion that he would be expected to lead those other demiG.o.ds, and he was afraid he would fail.

You'll tear each other apart, Boreas had promised.

Jason had been trained never to show fear. He was sure of that from his dream with the wolves. He was supposed to act confident, even if he didn't feel it. But Leo and Piper were depending on him, and he was terrified of failing them. If he had to lead a group of six-six who might not get along-that would be even worse.

"I don't know," he said at last. "I guess the other four will show up when the time is right. Who knows? Maybe they're on some other quest right now."

Leo grunted. "I bet their sewer is nicer than ours."

The draft picked up, blowing toward the south end of the tunnel.

"Get some rest, Leo," Jason said. "I'll take first watch."

It was hard to measure time, but Jason figured his friends slept about four hours. Jason didn't mind. Now that he was resting, he didn't really feel the need for more sleep. He'd been conked out long enough on the dragon. Plus, he needed time to think about the quest, his sister Thalia, and Hera's warnings. He also didn't mind Piper's using him for a pillow. She had a cute way of breathing when she slept-inhaling through the nose, exhaling with a little puff through the mouth. He was almost disappointed when she woke up.

Finally they broke camp and started down the tunnel.

It twisted and turned and seemed to go on forever. Jason wasn't sure what to expect at the end-a dungeon, a mad scientist's lab, or maybe a sewer reservoir where all Porta-Potty sludge ends up, forming an evil toilet face large enough to swallow the world.

Instead, they found polished steel elevator doors, each one engraved with a cursive letter M. Next to the elevator was a directory, like for a department store.

"M for Macy's?" Piper guessed. "I think they have one in downtown Chicago."

"Or Monocle Motors still?" Leo said. "Guys, read the directory. It's messed up."

Parking, Kennels, Main Entrance: Sewer Level Furnishings and Cafe M: 1 Women's Fashion and Magical Appliances: 2 Men's Wear and Weaponry: 3 Cosmetics, Potions, Poisons & Sundries: 4 "Kennels for what?" Piper said. "And what kind of department store has its entrance in a sewer?"

"Or sells poisons," Leo said. "Man, what does 'sundries' even mean? Is that like underwear?"

Jason took a deep breath. "When in doubt, start at the top."

The doors slid open on the fourth floor, and the scent of perfume wafted into the elevator. Jason stepped out first, sword ready.

"Guys," he said. "You've got to see this."

Piper joined him and caught her breath. "This is not Macy's."

The department store looked like the inside of a kaleidoscope. The entire ceiling was a stained gla.s.s mosaic with astrological signs around a giant sun. The daylight streaming through it washed everything in a thousand different colors. The upper floors made a ring of balconies around a huge central atrium, so they could see all the way down to the ground floor. Gold railings glittered so brightly, they were hard to look at.

Aside from the stained gla.s.s ceiling and the elevator, Jason couldn't see any other windows or doors, but two sets of gla.s.s escalators ran between the levels. The carpeting was a riot of oriental patterns and colors, and the racks of merchandise were just as bizarre. There was too much to take it at once, but Jason saw normal stuff like shirt racks and shoe trees mixed in with armored manikins, beds of nails, and fur coats that seemed to be moving.

Leo stepped to the railing and looked down. "Check it out."

In the middle of the atrium a fountain sprayed water twenty feet into the air, changing color from red to yellow to blue. The pool glittered with gold coins, and on either side of the fountain stood a gilded cage-like an oversize canary cage.

Inside one, a miniature hurricane swirled, and lightning flashed. Somebody had imprisoned the storm spirits, and the cage shuddered as they tried to get out. In the other, frozen like a statue, was a short, buff satyr, holding a tree-branch club.

"Coach Hedge!" Piper said. "We've got to get down there."

A voice said, "May I help you find something?"

All three of them jumped back.

A woman had just appeared in front of them. She wore an elegant black dress with diamond jewelry, and she looked like a retired fashion model-maybe fifty years old, though it was hard for Jason to judge. Her long dark hair swept over one shoulder, and her face was gorgeous in that surreal super-model way-thin and haughty and cold, not quite human. With their long red-painted nails, her fingers looked more like talons.

She smiled. "I'm so happy to see new customers. How may I help you?"

Leo glanced at Jason like, All yours.

"Um," Jason started, "is this your store?"

The woman nodded. "I found it abandoned, you know. I understand so many stores are, these days. I decided it would make the perfect place. I love collecting tasteful objects, helping people, and offering quality goods at a reasonable price. So this seemed a good ... how do you say ... first acquisition in this country."

She spoke with a pleasing accent, but Jason couldn't guess where from. Clearly she wasn't hostile, though. Jason started to relax. Her voice was rich and exotic. Jason wanted to hear more.

"So you're new to America?" he asked.

"I am ... new," the woman agreed. "I am the Princess of Colchis. My friends call me Your Highness. Now, what are you looking for?"

Jason had heard of rich foreigners buying American department stores. Of course most of the time they didn't sell poisons, living fur coats, storm spirits, or satyrs, but still-with a nice voice like that, the Princess of Colchis couldn't be all bad.

Piper poked him in the ribs. "Jason ..."

"Um, right. Actually, Your Highness ..." He pointed to the gilded cage on the first floor. "That's our friend down there, Gleeson Hedge. The satyr. Could we ... have him back, please?"

"Of course!" the princess agreed immediately. "I would love to show you my inventory. First, may I know your names?"

Jason hesitated. It seemed like a bad idea to give out their names. A memory tugged at the back of his mind-something Hera had warned him about, but it seemed fuzzy.

On the other hand, Her Highness was on the verge of cooperating. If they could get what they wanted without a fight, that would be better. Besides, this lady didn't seem like an enemy.

Piper started to say, "Jason, I wouldn't-"

"This is Piper," he said. "This is Leo. I'm Jason."

The princess fixed her eyes on him and, just for a moment, her face literally glowed, blazing with so much anger, Jason could see her skull beneath her skin. Jason's mind was getting blurrier, but he knew something didn't seem right. Then the moment pa.s.sed, and Her Highness looked like a normal elegant woman again, with a cordial smile and a soothing voice.

"Jason. What an interesting name," she said, her eyes as cold as the Chicago wind. "I think we'll have to make a special deal for you. Come, children. Let's go shopping."

PIPER WANTED TO RUN FOR THE ELEVATOR.

Her second choice: attack the weird princess now, because she was sure a fight was coming. The way the lady's face glowed when she'd heard Jason's name had been bad enough. Now Her Highness was smiling like nothing had happened, and Jason and Leo didn't seem to think anything was wrong.

The princess gestured toward the cosmetics counter. "Shall we start with the potions?"

"Cool," Jason said.

"Guys," Piper interrupted, "we're here to get the storm spirits and Coach Hedge. If this-princess-is really our friend-"

"Oh, I'm better than a friend, my dear," Her Highness said. "I'm a saleswoman." Her diamonds sparkled, and her eyes glittered like a snake's-cold and dark. "Don't worry. We'll work our way down to the first floor, eh?"

Leo nodded eagerly. "Sure, yeah! That sounds okay. Right, Piper?"

Piper did her best to stare daggers at him: No, it is not okay!

"Of course it's okay." Her Highness put her hands on Leo's and Jason's shoulders and steered them toward the cosmetics. "Come along, boys."

Piper didn't have much choice except to follow.

She hated department stores-mostly because she'd gotten caught stealing from several of them. Well, not exactly caught, and not exactly stealing. She'd talked salesmen into giving her computers, new boots, a gold ring, once even a lawn mower, though she had no idea why she wanted one. She never kept the stuff. She just did it to get her dad's attention. Usually she talked her neighborhood UPS guy into taking the stuff back. But of course the salesmen she duped always came to their senses and called the police, who eventually tracked her down.

Anyway, she wasn't thrilled to be back in a department store-especially one run by a crazy princess who glowed in the dark.
