She closed her eyes and swooned. Two campers rushed forward and caught her. A third ran to the side of the amphitheater and grabbed a bronze three-legged stool, like they'd been trained for this duty. They eased Rachel onto the stool in front of the ruined hearth. Without the fire, the night was dark, but green mist started swirling around Rachel's feet. When she opened her eyes, they were glowing. Emerald smoke issued from her mouth. The voice that came out was raspy and ancient-the sound a snake would make if it could talk: "Child of lightning, beware the earth, The giants' revenge the seven shall birth, The forge and dove shall break the cage, And death unleash through Hera's rage."

On the last word, Rachel collapsed, but her helpers were waiting to catch her. They carried her away from the hearth and laid her in the corner to rest.

"Is that normal?" Piper asked. Then she realized she'd spoken into the silence, and everyone was looking at her. "I mean... does she spew green smoke a lot?"

"G.o.ds, you're dense!" Drew sneered. "She just issued a prophecy-Jason's prophecy to save Hera! Why don't you just-"

"Drew," Annabeth snapped. "Piper asked a fair question. Something about that prophecy definitely isn't normal. If breaking Hera's cage unleashes her rage and causes a bunch of death ... why would we free her? It might be a trap, or-or maybe Hera will turn on her rescuers. She's never been kind to heroes."

Jason rose. "I don't have much choice. Hera took my memory. I need it back. Besides, we can't just not help the queen of the heavens if she's in trouble."

A girl from Hephaestus cabin stood up-Nyssa, the one with the red bandanna. "Maybe. But you should listen to Annabeth. Hera can be vengeful. She threw her own son-our dad-down a mountain just because he was ugly."

"Real ugly," snickered someone from Aphrodite.

"Shut up!" Nyssa growled. "Anyway, we've also got to think -why beware the earth? And what's the giants' revenge? What are we dealing with here that's powerful enough to kidnap the queen of the heavens?"

No one answered, but Piper noticed Annabeth and Chiron having a silent exchange. Piper thought it went something like: Annabeth: The giants' revenge ... no, it can't be.

Chiron: Don't speak of it here. Don't scare them.

Annabeth: You're kidding me! We can't be that unlucky.

Chiron: Later, child. If you told them everything, they would be too terrified to proceed.

Piper knew it was crazy to think she could read their expressions so well-two people she barely knew. But she was absolutely positive she understood them, and it scared the jujubes out of her.

Annabeth took a deep breath. "It's Jason's quest," she announced, "so it's Jason's choice. Obviously, he's the child of lightning. According to tradition, he may choose any two companions."

Someone from the Hermes cabin yelled, "Well, you, obviously, Annabeth. You've got the most experience."

"No, Travis," Annabeth said. "First off, I'm not helping Hera. Every time I've tried, she's deceived me, or it's come back to bite me later. Forget it. No way. Secondly, I'm leaving first thing in the morning to find Percy."

"It's connected," Piper blurted out, not sure how she got the courage. "You know that's true, don't you? This whole business, your boyfriend's disappearance-it's all connected."

"How?" demanded Drew. "If you're so smart, how?"

Piper tried to form an answer, but she couldn't.

Annabeth saved her. "You may be right, Piper. If this is connected, I'll find out from the other end-by searching for Percy. As I said, I'm not about to rush off to rescue Hera, even if her disappearance sets the rest of the Olympians fighting again. But there's another reason I can't go. The prophecy says otherwise."

"It says who I pick," Jason agreed. "The forge and dove shall break the cage. The forge is the symbol of Vul-Hephaestus."

Under the Cabin Nine banner, Nyssa's shoulders slumped, like she'd just been given a heavy anvil to carry. "If you have to beware the earth," she said, "you should avoid traveling overland. You'll need air transport."

Piper was about to call out that Jason could fly. But then she thought better of it. That was for Jason to tell them, and he wasn't volunteering the information. Maybe he figured he'd freaked them out enough for one night.

"The flying chariot's broken," Nyssa continued, "and the pegasi, we're using them to search for Percy. But maybe Hephaestus cabin can help figure out something else to help. With Jake incapacitated, I'm senior camper. I can volunteer for the quest."

She didn't sound enthusiastic.

Then Leo stood up. He'd been so quiet, Piper had almost forgotten he was there, which was totally not like Leo.

"It's me," he said.

His cabinmates stirred. Several tried to pull him back to his seat, but Leo resisted.

"No, it's me. I know it is. I've got an idea for the transportation problem. Let me try. I can fix this!"

Jason studied him for a moment. Piper was sure he was going to tell Leo no. Then he smiled. "We started this together, Leo. Seems only right you come along. You find us a ride, you're in."

"Yes!" Leo pumped his fist.

"It'll be dangerous," Nyssa warned him. "Hardship, monsters, terrible suffering. Possibly none of you will come back alive."

"Oh." Suddenly Leo didn't look so excited. Then he remembered everyone was watching. "I mean ... Oh, cool! Suffering? I love suffering! Let's do this."

Annabeth nodded. "Then, Jason, you only need to choose the third quest member. The dove-"

"Oh, absolutely!" Drew was on her feet and flashing Jason a smile. "The dove is Aphrodite. Everybody knows that. I am totally yours."

Piper's hands clenched. She stepped forward. "No."

Drew rolled her eyes. "Oh, please, Dumpster girl. Back off."

"I had the vision of Hera; not you. I have to do this."

"Anyone can have a vision," Drew said. "You were just at the right place at the right time." She turned to Jason. "Look, fighting is all fine, I suppose. And people who build things ..." She looked at Leo in disdain. "Well, I suppose someone has to get their hands dirty. But you need charm on your side. I can be very persuasive. I could help a lot."

The campers started murmuring about how Drew was pretty persuasive. Piper could see Drew winning them over. Even Chiron was scratching his beard, like Drew's partic.i.p.ation suddenly made sense to him.

"Well ..." Annabeth said. "Given the wording of the prophecy-"

"No!" Piper's own voice sounded strange in her ears-more insistent, richer in tone. "I'm supposed to go."

Then the weirdest thing happened. Everyone started nodding, muttering that hmm, Piper's point of view made sense too. Drew looked around, incredulous. Even some of her own campers were nodding.

"Get over it!" Drew snapped at the crowd. "What can Piper do?"

Piper tried to respond, but her confidence started to wane. What could she offer? She wasn't a fighter, or a planner, or a fixer. She had no skills except getting into trouble and occasionally convincing people to do stupid things.

Plus, she was a liar. She needed to go on this quest for reasons that went way beyond Jason-and if she did go, she'd end up betraying everyone there. She heard that voice from the dream: Do our bidding, and you may walk away alive. How could she make a choice like that-between helping her father and helping Jason?

"Well," Drew said smugly, "I guess that settles it."

Suddenly there was collective gasp. Everyone stared at Piper like she'd just exploded. She wondered what she'd done wrong. Then she realized there was a reddish glow around her.

"What?" she demanded.

She looked above her, but there was no burning symbol like the one that appeared over Leo. Then she looked down and yelped.

Her clothes ... what in the world was she wearing? She despised dresses. She didn't own a dress. But now she was adorned in a beautiful white sleeveless gown that went down to her ankles, with a V-neck so low it was totally embarra.s.sing. Delicate gold armbands circled her biceps. An intricate necklace of amber, coral, and gold flowers glittered on her chest, and her hair ...

"Oh, G.o.d," she said. "What's happened?"

A stunned Annabeth pointed at Piper's dagger, which was now oiled and gleaming, hanging at her side on a golden cord. Piper didn't want to draw it. She was afraid of what she would see. But her curiosity won out. She unsheathed Katoptris and stared at her reflection in the polished metal blade. Her hair was perfect: lush and long and chocolate brown, braided with gold ribbons down one side so it fell across her shoulder. She even wore makeup, better than Piper would ever know how to do herself-subtle touches that made her lips cherry red and brought out all the different colors in her eyes.

She was...she was...

"Beautiful," Jason exclaimed. "Piper, you ... you're a knockout."

Under different circ.u.mstances, that would've been the happiest moment of her life. But now everyone was staring at her like she was a freak. Drew's face was full of horror and revulsion. "No!" she cried. "Not possible!"

"This isn't me," Piper protested. "I-don't understand."

Chiron the centaur folded his front legs and bowed to her, and all the campers followed his example.

"Hail, Piper McLean," Chiron announced gravely, as if he were speaking at her funeral. "Daughter of Aphrodite, lady of the doves, G.o.ddess of love."

LEO DIDN'T STICK AROUND AFTER PIPER turned beautiful. Sure, it was amazing and all-She's got makeup! It's a miracle! -but Leo had problems to deal with. He ducked out of the amphitheater and ran into the darkness, wondering what he'd gotten himself into.

He'd stood up in front of a bunch of stronger, braver demiG.o.ds and volunteered-volunteered-for a mission that would probably get him killed.

He hadn't mentioned seeing Ta Callida, his old babysitter, but as soon as he'd heard about Jason's vision-the lady in the black dress and shawl-Leo knew it was the same woman. Ta Callida was Hera. His evil babysitter was the queen of the G.o.ds. Stuff like that could really deep-fry your brain.

He trudged toward the woods and tried not to think about his childhood-all the messed-up things that had led to his mother's death. But he couldn't help it.

The first time Ta Callida tried to kill him, he must've been about two. Ta Callida was looking after him while his mother was at the machine shop. She wasn't really his aunt, of course-just one of the old women in the community, a generic ta who helped watch the kids. She smelled like a honey-baked ham, and always wore a widow's dress with a black shawl.

"Let's set you down for a nap," she said. "Let's see if you are my brave little hero, eh?"

Leo was sleepy. She nestled him into his blankets in a warm mound of red and yellow-pillows? The bed was like a cubbyhole in the wall, made of blackened bricks, with a metal slot over his head and a square hole far above, where he could see the stars. He remembered resting comfortably, grabbing at sparks like fireflies. He dozed, and dreamed of a boat made of fire, sailing through the cinders. He imagined himself on board, navigating the sky. Somewhere nearby, Ta Callida sat in her rocking chair-creak, creak, creak-and sang a lullaby. Even at two, Leo knew the difference between English and Spanish, and he remembered being puzzled because Ta Callida was singing in a language that was neither.

Everything was fine until his mother came home. She screamed and raced over to s.n.a.t.c.h him up, yelling at Ta Callida, "How could you?" But the old lady had disappeared.

Leo remembered looking over his mother's shoulder at the flames curling around his blankets. Only years later had he realized he'd been sleeping in a blazing fireplace.

The weirdest thing? Ta Callida hadn't been arrested or even banished from their house. She appeared again several times over the next few years. Once when Leo was three, she let him play with knives. "You must learn your blades early," she insisted, "if you are to be my hero someday." Leo managed not to kill himself, but he got the feeling Ta Callida wouldn't have cared one way or the other.

When Leo was four, Ta found a rattlesnake for him in a nearby cow pasture. She gave him a stick and encouraged him to poke the animal. "Where is your bravery, little hero? Show me the Fates were right to choose you." Leo stared down at those amber eyes, hearing the dry shh-shh-ssh of the snake's rattle. He couldn't bring himself to poke the snake. It didn't seem fair. Apparently the snake felt the same way about biting a little kid. Leo could've sworn it looked at Ta Callida like, Are you nuts, lady? Then it disappeared into the tall gra.s.s.

The last time she babysat him, Leo was five. She brought him a pack of crayons and a pad of paper. They sat together at the picnic table in back of the apartment complex, under an old pecan tree. While Ta Callida sang her strange songs, Leo drew a picture of the boat he'd seen in the flames, with colorful sails and rows of oars, a curved stern, and an awesome masthead. When he was almost done, about to sign his name the way he'd learned in kindergarten, a wind s.n.a.t.c.hed the picture away. It flew into the sky and disappeared.

Leo wanted to cry. He'd spent so much time on that picture-but Ta Callida just clucked with disappointment.

"It isn't time yet, little hero. Someday, you'll have your quest. You'll find your destiny, and your hard journey will finally make sense. But first you must face many sorrows. I regret that, but heroes cannot be shaped any other way. Now, make me a fire, eh? Warm these old bones."

A few minutes later, Leo's mom came out and shrieked with horror. Ta Callida was gone, but Leo sat in the middle of a smoking fire. The pad of paper was reduced to ashes. Crayons had melted into a bubbling puddle of multicolored goo, and Leo's hands were ablaze, slowly burning through the picnic table. For years afterward, people in the apartment complex would wonder how someone had seared the impressions of a five-year-old's hands an inch deep into solid wood.

Now Leo was sure that Ta Callida, his psychotic babysitter, had been Hera all along. That made her, what-his G.o.dly grandmother? His family was even more messed up than he realized.

He wondered if his mother had known the truth. Leo remembered after that last visit, his mom took him inside and had a long talk with him, but he only understood some of it.

"She can't come back again." His mom had a beautiful face with kind eyes, and curly dark hair, but she looked older than she was because of hard work. The lines around her eyes were deeply etched. Her hands were callused. She was the first person from their family to graduate from college. She had a degree in mechanical engineering and could design anything, fix anything, build anything.

No one would hire her. No company would take her seriously, so she ended up in the machine shop, trying to make enough money to support the two of them. She always smelled of machine oil, and when she talked with Leo, she switched from Spanish to English constantly-using them like complementary tools. It took Leo years to realize that not everyone spoke that way. She'd even taught him Morse code as a kind of game, so they could tap messages to each other when they were in different rooms: I love you. You okay? Simple things like that.

"I don't care what Callida says," his mom told him. "I don't care about destiny and the Fates. You're too young for that. You're still my baby."

She took his hands, looking for burn marks, but of course there weren't any. "Leo, listen to me. Fire is a tool, like anything else, but it's more dangerous than most. You don't know your limits. Please, promise me-no more fire until you meet your father. Someday, mijo, you will meet him. He'll explain everything."

Leo had heard that since he could remember. Someday he would meet his dad. His mom wouldn't answer any questions about him. Leo had never met him, never even seen pictures, but she talked like he'd just gone to the store for some milk and he'd be back any minute. Leo tried to believe her. Someday, everything would make sense.

For the next couple of years, they were happy. Leo almost forgot about Ta Callida. He still dreamed of the flying boat, but the other strange events seemed like a dream too.

It all came apart when he was eight. By then, he was spending every free hour at the shop with his mom. He knew how to use the machines. He could measure and do math better than most adults. He'd learned to think three-dimensionally, solving mechanical problems in his head the way his mom did.

One night, they stayed late because his mom was finishing a drill bit design she hoped to patent. If she could sell the prototype, it might change their lives. She'd finally get a break.

As she worked, Leo pa.s.sed her supplies and told her corny jokes, trying to keep her spirits up. He loved it when he could make her laugh. She'd smile and say, "Your father would be proud of you, mijo. You'll meet him soon, I'm sure."

Mom's works.p.a.ce was at the very back of the shop. It was kind of creepy at night, because they were the only ones there. Every sound echoed through the dark warehouse, but Leo didn't mind as long as he was with his mom. If he did wander the shop, they could always keep in touch with Morse code taps. Whenever they were ready to leave, they had to walk through the entire shop, through the break room, and out to the parking lot, locking the doors behind them.

That night after finishing up, they'd just gotten to the break room when his mom realized she didn't have her keys.

"That's funny." She frowned. "I know I had them. Wait here, mijo. I'll only be a minute."

She gave him one more smile-the last one he'd ever get -and she went back into the warehouse.

She'd only been gone a few heartbeats when the interior door slammed shut. Then the exterior door locked itself.

"Mom?" Leo's heart pounded. Something heavy crashed inside the warehouse. He ran to the door, but no matter how hard he pulled or kicked, it wouldn't open. "Mom!" Frantically, he tapped a message on the wall: You okay?

"She can't hear you," a voice said.

Leo turned and found himself facing a strange woman. At first he thought it was Ta Callida. She was wrapped in black robes, with a veil covering her face.

"Ta?" he said.

The woman chuckled, a slow gentle sound, as if she were half asleep. "I am not your guardian. Merely a family resemblance."

"What-what do you want? Where's my mom?"

"Ah ... loyal to your mother. How nice. But you see, I have children too ... and I understand you will fight them someday. When they try to wake me, you will prevent them. I cannot allow that."

"I don't know you. I don't want to fight anybody."
