For the first time Clary had cause to bless her small size. She was able to dart through the crowd, her gaze catching on desperate tableaux of fighting. There, a Nephilim barely older than she was waged a desperate battle against one of the Endarkened, twice the Shadowhunter’s size, who forced her down into the blood-slicked snow; a blade swung out, and then a shriek, and a seraph blade darkened forever. A dark-haired young man in black Shadowhunter gear stood over the body of a dead warrior in red. He held a bloody sword in one hand, and tears were running down his face, unchecked. Nearby a Silent Brother, a sight unexpected but welcome in his parchment robes, crushed the skull of a Dark Shadowhunter with one blow from his wooden staff; the Endarkened crumpled in silence. A man fell to his knees, wrapping his arms around the legs of a woman in red gear; she looked at him dispassionately, then drove her sword down between his shoulder blades. None of the warriors moved to stop her.

Clary burst out on the other side of the crowd and found herself beside the Citadel. Its walls were shining with an intense light. Through the arch of the scissor gate, she thought she could see the glow of something red-gold like fire. She scrabbled for the stele at her belt, took hold of it, put the tip to the wall—and froze.

Only feet from her, a Dark Shadowhunter had slipped away from the battle and toward the Citadel gates. He carried a mace and flail under his arm; with a grinning glance back at the battle, he ducked through the Citadel gate—

And the scissors closed. There was no scream, but the sickening crunch of bone and gristle was audible even through the noise of battle. A gout of blood sprayed across the closed gate, and Clary realized it was not the first. There were other stains, fanned across the Citadel wall, darkening the ground beneath—

She turned away, her stomach clenching, and pressed her stele harder against the stone. She began to force her mind to thoughts of Alicante, trying to visualize the grassy space before the Gard, trying to push away the distractions all around her.

“Drop the stele, Valentine’s daughter,” said a cold, even voice.

She froze. Behind her stood Amatis, sword in hand, the sharp tip pointing directly at Clary. There was a feral grin on her face. “That’s right,” she said. “Drop the stele to the ground and come with me. I know someone who’ll be very pleased to see you.”

“Move, Clarissa.” Amatis jabbed Clary in the side with the tip of her sword—not hard enough to cut through her jacket, but enough to make Clary uncomfortable. Clary had dropped her stele; it lay feet away in the filthy snow, shining with a tantalizing glimmer. “Stop dawdling.”

“You can’t hurt me,” Clary said. “Sebastian’s given orders.”

“Orders not to kill you,” Amatis agreed. “He never said anything about hurting you. I’ll happily turn you over to him with all your fingers missing, girl. Don’t think I won’t.”

Clary glared before turning around and letting Amatis herd her toward the battle. Her gaze was darting among the Endarkened, looking for a familiar fair head in the sea of scarlet. She needed to know how much time she had before Amatis threw her down at Sebastian’s feet and the chance to fight or run was over. Amatis had taken Heosphoros, of course, and the Morgenstern blade now dangled at the older woman’s hip, the stars along the ridge winking in the dim light. “I bet you don’t even know where he is,” Clary said.

Amatis jabbed her again, and Clary lurched forward, almost stumbling over the dead body of a Dark Shadowhunter. The ground was a churned-up mass of snow and dirt and blood. “I am Sebastian’s first lieutenant; I always know where he is. That is why I am the one he trusts to bring you to him.”

“He doesn’t trust you. He doesn’t care about you, or anything. Look.” They had reached the bump of a small ridge; Clary slowed to a stop and swept her arm out, indicating the battlefield. “Look how many of you are falling—Sebastian just wants cannon fodder. Just wants to use you up.”

“Is that what you see? I see dead Nephilim.” Clary could see Amatis out of the corner of her eye. Her gray-brown hair floated on the cold air, and her eyes were hard. “You think the Clave is not overmatched? Look. Look there.” She jabbed with a finger, and Clary looked, unwillingly. The two halves of Sebastian’s army had closed in and were encircling the Nephilim in their midst. Many of the Nephilim were fighting with skill and viciousness. They were, in their own strange way, lovely to watch in battle; the light of their seraph blades traced patterns on the dark sky. Not that it changed the fact that they were doomed. “They did what they always do when there’s an attack outside Idris and a Conclave is not near. They sent through the Portal whoever arrived at the Gard first. Some of these warriors have never fought in a real battle before. Some of them have fought in too many. None of them are prepared to kill an enemy that bears the faces of their sons, lovers, friends, parabatai.” She spat the last word. “The Clave does not understand our Sebastian or his forces, and they will be dead before they do.”

“Where did they come from?” Clary demanded. “The Endarkened. The Clave said there were only twenty of them, and there was no way for Sebastian to hide their numbers. How—”

Amatis threw her head back and laughed. “As if I’d tell you. Sebastian has allies in more places than you know, little one.”

“Amatis.” Clary tried to keep her voice steady. “You’re one of us. Nephilim. You’re Luke’s sister.”

“He’s a Downworlder, and no brother of mine. He should have killed himself when Valentine told him to.”

“You don’t mean that. You were happy to see him when we came to your house. I know you were.”

This time the jab of the blade’s tip between her shoulder blades was more than uncomfortable: It hurt. “I was trapped then,” Amatis said. “Thinking I needed the approval of the Clave and the Council. The Nephilim took everything from me.” She turned to glare at the Citadel. “The Iron Sisters took my mother. Then an Iron Sister presided over my divorce. They cut my marriage Marks in two, and I cried with the pain of it. They have no hearts in them, only adamas, and the Silent Brothers too. You think they are kind, that the Nephilim are kind, because they are good, but goodness is not kindness, and there is nothing crueler than virtue.”

“But we can choose,” Clary said, but how could you explain to someone who didn’t understand that their choices had been taken away, that there was such a thing as free will?

“Oh, for Hell’s sake, be quiet—” Amatis broke off, stiffening.

Clary followed her gaze. For a moment she couldn’t see what the other woman was staring at. She saw the chaos of fighting, blood in the snow, the spark of starlight on blades and the harsh glow of the Citadel. Then she realized that the battle seemed to be resolving itself into an odd sort of pattern—something was cutting a path through the middle of the crowd, like a ship slicing through water, leaving chaos in its wake. A slender black-clad Shadowhunter with bright hair, moving so fast, it was like watching fire spring from ridge to ridge in a forest, catching everything ablaze.

Only in this case the forest was Sebastian’s army, Endarkened falling one by one. Falling so quickly, they barely had time to reach for their weapons, much less raise them. And as they fell, others began to fall back, confused and uncertain, so that Clary could see the space that was being cleared in the middle of the battle, and who stood in the center of it.
