Set roared with outrage, but the avatar began to shrink. Before we could even close the distance, Amos was kneeling on the floor of the Hall of Ages, surrounded by only the thinnest of glowing red shields. Magical ropes now bound him tight. Sarah Jacobi stood behind him, holding the black la.s.so like a leash. One of her netjeri blades was pressed against Amos's neck.

"Stop!" she commanded us. "This ends now."

My friends hesitated. The rebel magicians turned and faced us warily.

Isis spoke in my mind: Regrettable, but we must let him die. He hosts Set, our old enemy.

That's my uncle! I replied.

He has been corrupted, Isis said. He is already gone.

"No!" I yelled. Our connection wavered. You can't share the mind of a G.o.d and have a disagreement. To be the Eye, you must act in perfect unison.

Carter seemed to be having similar trouble with Horus. He summoned the hawk warrior avatar, but almost immediately it dissipated and dropped Carter to the floor.

"Come on, Horus!" he growled. "We have to help."

Sarah Jacobi's laugh sounded like metal sc.r.a.ped through sand.

"Do you see?" She pulled tight on the noose around Amos's neck. "This is what comes from the path of the G.o.ds! Confusion. Chaos. Set himself in the Hall of Ages! Even you misguided fools cannot deny this is wrong!"

Amos clawed at his throat. He growled in outrage, but it was Set's voice that spoke. "I try to do something nice, and this is my thanks? You should have let me kill them, Amos!"

I stepped forward, careful to make no sudden movements. "Jacobi, you don't understand. Amos is channeling Set's power, but he's in control. He could have killed you, but he didn't. Set was a lieutenant of Ra. He's a useful ally, properly managed."

Set snorted. "Useful, yes! I don't know about the properly managed business. Let me go, puny magicians, so I can crush you!"

I glared at my uncle. "Set! Not helping!"

Amos's expression changed from anger to concern. "Sadie!" he said with his own voice. "Go: fight Apophis. Leave me here!"

"No," I said. "You're the Chief Lector. We'll fight for the House of Life."

I didn't look behind me, but I hoped that my friends would agree. Otherwise my last stand would be very, very short.

Jacobi sneered. "Your uncle is a servant of Set! You and your brother are sentenced to death. The rest of you, lay down your weapons. As your new Chief Lector, I will give you amnesty. Then we will battle Apophis together."

"You're in league with Apophis!" I yelled.

Jacobi's face turned stony cold. "Treason."

She thrust out her staff. "Ha-di."

I raised my wand, but Isis wasn't helping me this time. I was just Sadie Kane, and my defenses were slow. The explosion ripped through my weak shields and threw me backward into a curtain of light. Images from the Age of the G.o.ds crackled around me-the founding of the world, the crowning of Osiris, the battle between Set and Horus-like having sixty different movies downloaded into my brain while being electrocuted. The light shattered, and I lay on the floor, dazed and drained.

"Sadie!" Carter charged toward me, but Kwai blasted him with a bolt of red lightning. Carter fell to his knees. I didn't even have the strength to cry out.

Jaz ran toward him. Little Shelby yelled, "Stop it! Stop it!" Our other initiates seemed stunned, unable to move.

"Give up," Jacobi said. I realized she was speaking with words of power, just like the ghost Setne had done. She was using magic to paralyze my friends. "The Kanes have brought you nothing but trouble. It's time this ended."

She lifted her netjeri blade from Amos's throat. Quick as light, she threw it at me. As the blade flew, my mind seemed to speed up. In that millisecond, I understood that Sarah Jacobi wouldn't miss. My end would be as painful as poor Leonid's, who was bleeding to death alone in the outer tunnel. Yet I could do nothing to defend myself.

A shadow crossed in front of me. A bare hand s.n.a.t.c.hed the blade out of the air. The meteoric iron turned gray and crumbled.

Jacobi's eyes widened. She hastily drew her second knife.

"Who are you?" she demanded.

"Walt Stone," he said, "blood of the pharaohs. And Anubis, G.o.d of the dead."

He stepped in front of me, shielding me from my enemies. Maybe my vision was double because I'd cracked my head, but I saw the two of them with equal clarity-both handsome and powerful, both quite angry.

"We speak with one voice," Walt said. "Especially on this matter. No one harms Sadie Kane."

He thrust out his hand. The floor split open at Sarah Jacobi's feet, and souls of the dead sprang up like weeds-skeletal hands, glowing faces, fanged shadows, and winged ba with their claws extended. They swarmed Sarah Jacobi, wrapping her in ghostly linen, and dragged her screaming into the chasm. The floor closed behind her, leaving no trace that she had ever existed.

The black noose slackened around Amos's neck, and the voice of Set laughed with delight. "That's my boy!"

"Shut up, Father," Anubis said.

In the Duat, Anubis looked as he always had, with his tousled dark hair and lovely brown eyes, but I'd never seen him filled with such rage. I realized that anyone who dared to hurt me would suffer his full wrath, and Walt wasn't going to hold him back.

Jaz helped Carter to his feet. His shirt was burned, but he looked all right. I suppose a blast of lightning wasn't the worst thing that had happened to him lately.

"Magicians!" Carter managed to stand tall and confident, addressing both our initiates and the rebels. "We're wasting time. Apophis is above, about to destroy the world. A few brave G.o.ds are holding him back for our sakes, for the sake of Egypt and the world of mortals, but they can't do it alone. Jacobi and Kwai led you astray. Unbind the Chief Lector. We have to work together."

Kwai snarled. Red electricity arced between his fingers. "Never. We do not bow to G.o.ds."

I managed to rise.

"Listen to my brother," I said. "You don't trust the G.o.ds? They are already helping us. Meanwhile, Apophis wants us to fight one another. Why do you think your attack was timed for this morning, at the same moment Apophis is rising? Kwai and Jacobi have sold you out. The enemy is right in front of you!"

Even the rebel magicians now turned to stare at Kwai. The remaining ropes fell away from Amos.

Kwai sneered. "You're too late."

His voice hummed with power. His robes turned from blue to bloodred. His eyes glowed, his pupils turning to reptilian slits. "Even now, my master destroys the old G.o.ds, sweeping away the foundations of your world. He will swallow the sun. All of you will die."

Amos got to his feet. Red sand swirled around him, but I had no doubt who was in charge now. His white robes shimmered with power. The leopard-skin cape of the Chief Lector gleamed on his shoulders. He held out his staff, and multicolored hieroglyphs filled the air.

"House of Life," he said. "To war!"

Kwai did not give up easily.

I suppose that's what happens when the Serpent of Chaos is invading your thoughts and filling you with unlimited rage and magic.

Kwai sent a chain of red lightning across the room, knocking over most of the other magicians, including his own followers. Isis must have protected me, because the electricity rippled over me with no effect. Amos didn't seem bothered in his swirling red tornado. Walt stumbled, but only briefly. Even Carter in his weakened state managed to turn aside the lightning with his pharaoh's crook.

The others weren't as lucky. Jaz collapsed. Then Julian. Then Felix and his squad of penguins. All our initiates and the rebels they'd been fighting crumpled unconscious to the floor. So much for a ma.s.sive offensive.

I summoned the power of Isis. I began to cast a binding charm; but Kwai wasn't done with his tricks. He raised his hands and created his own sandstorm. Dozens of whirlwinds spun through the hall, thickening and forming into creatures of sand-sphinxes, crocodiles, wolves, and lions. They attacked in every direction, even pouncing on our defenseless friends.

"Sadie!" Amos warned. "Protect them!"

I quickly changed spells-casting hasty shields over our unconscious initiates. Amos blasted the monsters one after the other, but they just kept re-forming.

Carter summoned his avatar. He charged at Kwai, but the red magician blasted him backward with a new surge of lightning. My poor brother slammed into a stone column, which collapsed on top of him. I could only hope his avatar had taken the brunt of the impact.

Walt released a dozen magical creatures at once-his sphinx, his camels, his ibis, even Philip of Macedonia. They charged at the sand creatures, trying to keep them away from the fallen magicians.

Then Walt turned to face Kwai.

"Anubis," Kwai hissed. "You should have stayed in your funeral parlor, boy G.o.d. You are outmatched."

By way of answer, Walt spread his hands. On either side of him, the floor cracked open. Two ma.s.sive jackals leaped from the crevices, their fangs bared. Walt's form shimmered. Suddenly he was dressed in Egyptian battle armor, a was staff twirling in his hands like a deadly fan blade.

Kwai roared. He blasted the jackals with waves of sand. He hurled lightning and words of power at Walt, but Walt deflected them with his staff, reducing Kwai's attacks to gray ashes.

The jackals harried Kwai from either side, sinking their teeth into his legs, while Walt stepped in and swung his staff like a golf club. He hit Kwai so hard, I imagined it echoed all the way through the Duat. The magician fell. His sand creatures vanished.

Walt called off his jackals. Amos lowered his staff. Carter rose from the rubble, looking dizzy but unharmed. We gathered around the fallen magician.

Kwai should have been dead. A line of blood trickled from his mouth. His eyes were gla.s.sy. But as I studied his face, he took a sharp breath and laughed weakly.

"Idiots," he rasped. "Sahei."

A bloodred hieroglyph burned against his chest: His robes erupted in flames. Before our eyes, he dissolved into sand and a wave of cold-the power of Chaos-rippled through the Hall of Ages. Columns shook. Chunks of stone fell from the ceiling. A slab the size of an oven crashed into the steps of the dais, almost crushing the pharaoh's throne.

"Bring down," I said, realizing what the hieroglyph meant. Even Isis seemed terrified by the invocation. "Sahei is Bring down."

Amos swore in Ancient Egyptian-something about donkeys trampling Kwai's ghost. "He used up his life force to cast this curse. The hall is already weakened. We'll have to leave before we're buried alive."

I glanced around us at the fallen magicians. Some of our initiates were starting to stir, but there was no way we could get them all to safety in time.

"We have to stop it!" I insisted. "We have four G.o.ds present! Can't we save the hall?"

Amos furrowed his brow. "The power of Set will not help me in this. He can only destroy, not restore."

Another column toppled. It broke across the floor, barely missing one of the unconscious rebels.

Walt-who looked quite good in armor, by the way-shook his head. "This is beyond Anubis. I'm sorry."

The floor rumbled. We had only seconds to live. Then we would be just another bunch of entombed Egyptians.

"Carter?" I asked.

He regarded me helplessly. He was still weak, and I realized his battle magic wouldn't be much good in this situation.

I sighed. "So it comes down to me, as always. Fine. You three shield the others as best you can. If this doesn't work, get out quickly."

"If what doesn't work?" Amos said, as more chunks of ceiling rained down around us. "Sadie, what are you planning?"

"Just a word, dear uncle." I raised my staff and called on the power of Isis.

She immediately understood what I needed. Together, we tried to find calm in the Chaos. I focused on the most peaceful, well-ordered moments of my life-and there weren't many. I remembered my sixth birthday party in Los Angeles with Carter, my dad and mum-the last clear memory I had of all of us together as a family. I imagined listening to music in my room at Brooklyn House while Khufu ate Cheerios on my dresser. I imagined sitting on the terrace with my friends, having a restful breakfast as Philip of Macedonia splashed in his pool. I remembered Sunday afternoons at Gran and Gramps's flat-m.u.f.fin on my lap, Gramps's rugby game on the telly, and Gran's horrible biscuits and weak tea on the table. Good times, those were.

Most important, I faced down my own chaos. I accepted my jumbled emotions about whether I belonged in London or New York, whether I was a magician or a schoolgirl. I was Sadie Kane, and if I survived today, I could b.l.o.o.d.y well balance it all. And, yes, I accepted Walt and Anubis...I gave up my anger and dismay. I imagined both of them with me, and if that was peculiar, well then, it fit right in with the rest of my life. I made peace with the idea. Walt was alive. Anubis was flesh and blood. I stilled my restlessness and let go of my doubts.

"Ma'at," I said.

I felt as if I'd struck a tuning fork against the foundation of the earth. Deep harmony resonated outward through every level of the Duat.

The Hall of Ages stilled. Columns rose and repaired themselves. The cracks in the ceiling and floor sealed. Holographic curtains of light blazed once again along either side of the hall, and hieroglyphs once more filled the air.

I collapsed into Walt's arms. Through my fuzzy vision, I saw him smiling down at me. Anubis, too. I could see them both, and I realized I didn't have to pick.

"Sadie, you did it," he said. "You're so amazing."

"Uh-huh," I muttered. "Good night."

They tell me I was only out a few seconds, but it felt like centuries. When I came to, the other magicians were back on their feet. Amos smiled down at me. "Up you come, my girl."

He helped me to my feet. Carter hugged me quite enthusiastically, almost as if he appreciated me properly for once.

"It's not over," Carter warned. "We have to get to the surface. Are you ready?"

I nodded, though neither of us was in good shape. We'd used up too much energy in the fight for the Hall of Ages. Even with the G.o.ds' help, we were in no condition to face Apophis. But we had little choice.

"Carter," Amos said formally, gesturing to the empty throne. "You are blood of the pharaohs, Eye of Horus. You carry the crook and flail, bestowed by Ra. The kingship is yours. Will you lead us, G.o.ds and mortals, against the enemy?"

Carter stood straight. I could see the doubt and fear in him, but possibly that was just because I knew him. I'd spoken his secret name. On the outside, he looked confident, strong, adult-even kingly.

[Yes, I said that. Don't get a big head, brother dear. You're still a huge dork.]

"I'll lead you," Carter said. "But the throne will have to wait. Right now, Ra needs us. We have to get to the surface. Can you show us the quickest way?"

Amos nodded. "And the rest of you?"

The other magicians shouted a.s.sent-even the former rebels.

"We aren't many," Walt observed. "What are your orders, Carter?"

"First we get reinforcements," he said. "It's time I summoned the G.o.ds to war."
