"Alexander?" she said, her voice rich with disbelief. "Alexander Lightwood?"
It was Camille.
"Jace." Lilith's voice came down like a whip across bare flesh; even Clary flinched at the sound of it. "I command you to-"
Jace's arm drew back-Clary tensed, bracing herself-and he flung the knife at Lilith. It whipped through the air, end over end, and sank into her chest; she staggered back, caught off balance. Lilith's heels skidded on the smooth stone; the demoness righted herself with a snarl, reaching down to pluck the knife from her ribs. Spitting something in a language Clary couldn't understand, she let it drop. It fell hissing to the ground, its blade half-eaten away, as if by a powerful acid.
She whirled on Clary. "What did you do to him? What did you do?" Her eyes had been all black a moment ago. Now they seemed to bulge and protrude. Small black serpents slithered from her eye sockets; Clary cried out and stepped back, almost tripping over a low hedge. This was the Lilith she had seen in Ithuriel's vision, with her slithering eyes and harsh, echoing voice. She advanced on Clary-
And suddenly Jace was between them, blocking Lilith's path. Clary stared. He was himself again. He seemed to burn with a righteous fire, as Raziel had by Lake Lyn that horrible night. He had drawn a seraph blade from his belt; the white-silver of it reflected in his eyes; blood dripped from the rent in his shirt and slicked his bare skin. The way he looked at her, at Lilith-if angels could rise up out of Hell, Clary thought, they would look like that. "Michael," he said, and Clary wasn't sure whether it was the strength of the name, or the rage in his voice, but the blade he held blazed up brighter than any seraph blade she'd ever seen. She looked aside for a moment, blinded, and saw Simon lying in a crumpled dark heap beside Sebastian's glass coffin.
Her heart twisted inside her chest. What if Sebastian's demon blood had poisoned him? The Mark of Cain wouldn't help him. It was something he had done willingly, to himself. For her. Simon.
"Ah, Michael." Lilith's voice was rich with laughter as she moved toward Jace. "The captain of the hosts of the Lord. I knew him."
Jace raised the seraph blade; it blazed like a star, so bright that Clary wondered if all the city could see it, like a searchlight piercing the sky. "Don't come any closer."
Lilith, to Clary's surprise, paused. "Michael slew the demon Sammael, whom I loved," she said. "Why is it, little Shadowhunter, that your angels are so cold and without mercy? Why do they break that which will not obey them?"
"I had no idea you were such a proponent of free will," said Jace, and the way he said it, his voice heavy with sarcasm, did more to reassure Clary that he was himself again than anything else would have. "How about letting us all walk off this roof now, then? Me, Simon, Clary? What do you say, demoness? It's over. You don't control me anymore. I won't hurt Clary, and Simon won't obey you. And that piece of filth you're trying to resuscitate-I suggest you get rid of him before he starts to rot. Because he isn't coming back, and he's way past his sell-by date."
Lilith's face twisted. She spat at Jace, and her spit was a black flame that hit the ground and became a snake that wiggled toward him, its jaws agape. He smashed it with a booted foot and lunged for the demoness, blade outstretched; but Lilith was gone like a shadow when light shone on it, vanishing and reforming just behind him. As he spun, she reached out almost lazily and slammed her open palm against his chest.
Jace went flying, Michael knocked from his hand, skittering across the stone tiles. Jace sailed through the air and struck the low roof wall with such force that splintering lines appeared in the stone. He hit the ground hard, visibly stunned.
Gasping, Clary ran for the fallen seraph blade, but never reached it. Lilith caught Clary up in two thin, icy hands and threw her with incredible force. Clary hurtled into a low hedge, the branches slashing viciously at her skin, opening up long cuts. She struggled to free herself, her dress tangled in the foliage. She heard the silk rip as she tore free and turned to see Lilith drag Jace to his feet, her hand fastened in the bloody front of his shirt.
She grinned at him, and her teeth were black too, and gleamed like metal. "I am glad you're on your feet, little Nephilim. I want to see your face when I kill you, not stab you in the back the way you did my son."
Jace wiped his sleeve across his face; he was bleeding from a long cut along his cheek, and the fabric came away red. "He's not your son. You donated some blood to him. That doesn't make him yours. Mother of warlocks-" He turned his head and spat, blood. "You're not anyone's mother."
Lilith's snake eyes darted back and forth furiously. Clary, disentangling herself painfully from the hedge, saw that each of the snake heads had two eyes of its own, glittering and red. Clary's stomach turned as the snakes moved, their gazes seeming to slither up and down Jace's body. "Cutting my rune apart. How crude," she spat.
"But effective," said Jace.
"You cannot win against me, Jace Herondale," she said. "You may be the greatest Shadowhunter this world has known, but I am more than a Greater Demon."
"Then, fight me," said Jace. "I'll give you a weapon. I'll have my seraph blade. Fight me one on one, and we'll see who wins."
Lilith looked at him, shaking her head slowly, her dark hair swirling around her like smoke. "I am the oldest of demons," she said. "I am not a man. I have no male pride for you to trick me with, and I am not interested in single combat. That is entirely a weakness of your sex, not mine. I am a woman. I will use any weapon and all weapons to get what I want." She let go of him them, with a half-contemptuous shove; Jace stumbled for a moment, righting himself quickly and reaching to the ground for the glittering blade of Michael.
He seized it just as Lilith laughed and raised her hands. Half-opaque shadows exploded from her open palms. Even Jace looked shocked as the shadows solidified into the forms of twin black shadowy demons with shimmering red eyes. They hit the ground, pawing and growling. They were dogs, Clary thought in amazement, two gaunt, vicious-looking black dogs that vaguely resembled Doberman pinschers.
"Hellhounds," breathed Jace. "Clary-"
He broke off as one of the dogs sprang toward him, its mouth opened as wide as a shark's, a loud, baying howl erupting from its throat. A moment later the second one leaped into the air, launching itself directly at Clary.
"Camille." Alec's head was spinning. "What are you doing here?"
He immediately realized that he sounded like an idiot. He fought down the urge to smack himself in the forehead. The last thing he wanted was to look like a fool in front of Magnus's ex-girlfriend.
"It was Lilith," said the vampire woman in a small, trembling voice. "She had her cult members break into the Sanctuary. It isn't warded against humans, and they're human-barely. They cut my chains and brought me here, to her." She raised her hands; the chains binding her wrists to the pipe rattled. "They brutalized me."
Alec crouched down, bringing his eyes on a level with Camille's. Vampires didn't bruise-they healed too quickly for that-but her hair was matted with blood on the left side, which made him think she was telling the truth. "Let's say I believe you," he said. "What did she want with you? Nothing in what I know about Lilith says she has a particular interest in vampires."
"You know why the Clave was holding me," she said. "You would have heard."
"You killed three Shadowhunters. Magnus said you claimed you were doing it because someone had ordered you to-" He broke off. "Lilith?"
