He was on the ground, and her heart, which had felt as if it were exploding inside her chest, slowed its beating slightly when she saw that his eyes were open. He was very pale, though, and breathing harshly enough that she could hear it. The Silent Brother was kneeling next to him, long pale fingers unsnapping the gear at Jace’s shoulder.

“What’s going on?” Clary asked, looking around wildly. A dozen Iron Sisters gazed back, impassive and silent. There were more Iron Sisters as well, on the other side of the chasm, watching unmoving as the Endarkened threw themselves into it. It was eerie. “What happened?”

“Sebastian,” Jace said through gritted teeth, and she dropped down beside him, across from the Silent Brother, as his gear peeled away and she saw the gash in his shoulder. “Sebastian happened.”

The wound was weeping fire.

Not blood but fire, tinged gold like the ichor of angels. Clary took a ragged breath and looked up to see Brother Zachariah looking back at her. She caught a single glimpse of his face, all angles and pallor and scars, before he drew a stele from his robe. Instead of setting it to Jace’s skin, as she would have expected, he set it to his own and carved a rune into his palm. He did it quickly, but Clary could feel the power that came from the rune. It made her shudder.

Stay still. This will end the hurt, he said in his soft omnidirectional whisper, and placed his hand over the fiery gash on Jace’s shoulder.

Jace cried out. His body half-lifted off the ground, and the fire that had bled like slow tears from his wound rose as if gasoline had been poured on it, searing up Brother Zachariah’s arm. Wildfire consumed the parchment sleeve of Zachariah’s robe; the Silent Brother jerked away, but not before Clary saw that the blaze was rising, consuming him. In the depths of the flame, as it wavered and crackled, Clary saw a shape—the shape of a rune that looked like two wings joined by a single bar. A rune she had seen before, standing on a rooftop in Manhattan: the first rune not from the Gray Book that she had ever visualized. It flickered and disappeared, so quickly that she wondered if she had imagined it. It seemed to be a rune that appeared to her in times of stress and panic, but what did it mean? Was it meant to be a way to help Jace—or Brother Zachariah?

The Silent Brother fell back silently into the snow, collapsing like a burned tree shivering to ashes.

A murmur tore through the ranks of the Iron Sisters. Whatever was happening to Brother Zachariah, it wasn’t supposed to be happening. Something had gone horribly wrong.

The Iron Sisters moved toward their fallen brother. They blocked Clary’s view of Zachariah as she reached for Jace. He was bucking and spasming on the ground, his eyes closed, his head tilted back. She looked around wildly. Through the gaps between the Iron Sisters she could see Brother Zachariah, thrashing on the ground: His body was shimmering, sizzling with fire. A cry burst from his throat—a human noise, the cry of a man in pain, not the silent mind-whisper of the Brothers. Sister Cleophas caught at him—parchment robes and fire, and Clary could hear the Sister’s voice rising, “Zachariah, Zachariah—”

But he was not the only one wounded. Some of the Nephilim were grouped around Jace, but many of the others were with their injured comrades, administering healing runes, searching their gear for bandages.

“Clary,” Jace whispered. He was trying to struggle up onto his elbows, but they wouldn’t hold him. “Brother Zachariah—what’s happened? What did I do to him—”

“Nothing. Jace. Lie still.” Clary sheathed her blade and fumbled his stele from his weapons belt with numb fingers. She reached to press the tip to his skin, but he writhed away from her, his body jerking.

“No,” he gasped. His eyes were huge and burning gold. “Don’t touch me. I’ll hurt you, too.”

“You won’t.” Desperate, she threw herself on top of him, the weight of her body bearing him backward into the snow. She reached for his shoulder as he twisted under her, his clothes and skin blood-slippery and fire-hot. Her knees slid to either side of his hips as she threw her full weight against his chest, pinning him down. “Jace,” she said. “Jace, please.” But his eyes wouldn’t focus on her, his hands spasming against the ground. “Jace,” she said, and put the stele to his skin, just over his wound.

And she was on the ship again with her father, with Valentine, and she was throwing everything she had, every bit of strength, every last atom of will and energy into crafting a rune, a rune that would burn down the world, that would reverse death, that would make the oceans fly up into the sky. Only, this time it was the simplest of runes, the rune every Shadowhunter learned in their first year of training:

Heal me.

The iratze took shape on Jace’s shoulder, the color spiraling from the tip so black that the light coming from the stars and the Citadel seemed to vanish into it. Clary could feel her own energy vanishing into it too as she drew. Never had she felt more like the stele was an extension of her own veins, that she was writing in her own blood, as if all the energy in her was being drawn out through her hand and fingers, her vision darkening as she fought to keep the stele steady, to finish the rune. The last thing she saw was the great burning whirl of a Portal, opening onto the impossible sight of Angel Square, before she slid into nothingness.

STRENGTH IN WHAT REMAINS

Raphael stood, hands in his pockets, and looked up at the demon towers, shimmering dark red. “Something’s going on,” he said. “Something unusual.”

Simon wanted to snap back that the unusual thing that was going on was that he’d just been kidnapped and taken to Idris for the second time in his life, but he was feeling too nauseated. He’d forgotten the way a Portal seemed to take you apart when you went through it and reassemble you on the other side with important pieces missing.

Also, Raphael was right. Something was going on. Simon had been in Alicante before, and he remembered the roads and the canals, the hill rising over it all with the Gard at the top. He remembered that on ordinary nights the streets were quiet, lit by the pale glow of the towers. But there was noise tonight, largely coming from the Gard and the hill, where lights were dancing as if a dozen bonfires had been lit. The demon towers were glowing an eerie red-gold.

“They change the color of the towers to convey messages,” said Raphael. “Gold for marriages and celebrations. Blue for the Accords.”

“What does red mean?” Simon asked.

“Magic,” said Raphael, his dark eyes narrowed. “Danger.”

He turned in a slow circle, looking around the quiet street, the large houses by the canal side. He was about a head shorter than Simon. Simon wondered how old he’d been when he’d been Turned. Fourteen? Fifteen? Only a little older than Maureen. Who had Turned him? Magnus knew but had never told.

“The Inquisitor’s house is there,” Raphael said, and pointed at one of the largest of the houses, with a pointed roof and balconies out over the canal. “But it is dark.”

Simon couldn’t deny that fact, though his unbeating heart gave a little leap as he looked at the place. Isabelle was living there now; one of those windows was her window. “They must all be up at the Gard,” he said. “They do that, for meetings and things.” He had no fond memories of the Gard himself, having been imprisoned there by the last Inquisitor. “We could go up there, I guess. See what’s going on.”
