City of Heavenly Fire

“Clary!” Jace shouted as one of the creatures heaved itself toward her, its circular mouth open. Ropes of yellow drool hung from it.

Thump. An arrow embedded itself in the roof of the demon’s mouth. The creature reared back, spitting black blood. Clary saw Alec seize another arrow, fit it, let it fly. Another demon reeled back, and then Isabelle was on it, her whip slashing back and forth, slicing it to ribbons. Simon had seized another demon and was holding it, his hands sinking into its fleshy gray body, and Jace plunged his sword into it. The demon collapsed, knocking Simon back to the floor: he landed on his backpack. Clary thought she heard a sound like breaking glass, but a moment later Simon was back up on his feet, Jace steadying him with a hand to the shoulder before they both turned back to the fight.

Ice had descended over Clary: the silent coldness of battle. The demon Alec had shot was writhing, trying to spit out the arrow lodged in its mouth; she stepped over to it and plunged her dagger into its body, black blood spraying up from the wounds, soaking her gear. The room was full of the rotten-garbage stench of demons, laced through with the acid of ichor; she gagged as the demon gave a last spasm and collapsed.

Alec was backing up, steadily letting arrow after arrow fly, sending the demons reeling back, wounded. As they struggled, Jace and Isabelle fell on them, slashing them to pieces with sword and whip. Clary followed their lead, leaping on another wounded demon, sawing away at the soft band of flesh under its mouth, her hand, coated in oily demon blood, slipping on the hilt of her dagger. The demon collapsed in on itself with a hiss, sending her crashing to the ground. The blade skittered out of her hand, and she threw herself after it, seized it up, and rolled to the side just as another demon lunged with an uncoiling of its powerful body.

It hit the space where she’d just been lying, and curled itself around, hissing, so that Clary found herself facing two open, gaping mouths. She readied her blade to let it fly, when there was a flash of silver-gold and Isabelle’s whip came down, slicing the thing in half.

It fell apart in two pieces, a jumbled mess of steaming internal organs pouring out. Even through the ice of battle, Clary was nearly sick. Demons usually died and vanished before you saw much of their insides. This one was still writhing, even in two pieces, twitching forward and back. Isabelle grimaced and raised her whip again—and the twitch turned into a sudden, violent jerk as half the monster twisted backward and sank its teeth into Isabelle’s leg.

Izzy screamed, slashing down with the whip, and it released her; she fell back, her leg going out from under her. Clary leaped forward, stabbing at the other half of the demon, plunging her dagger into the creature’s back until it crumbled apart under her and she found herself kneeling in a welter of demon blood, drenched blade in her hand, gasping.

There was silence. The ringing alarm had stopped, and the demons were gone. They had all been slaughtered, but there was no joy of victory. Isabelle was on the ground, her whip curled around her wrist, blood pouring from a crescent-shaped slash in her left leg. She was gasping, her eyelids fluttering.

“Izzy!” Alec dropped his bow and launched himself across the bloody floor at his sister. He fell to his knees, hauling her up into his lap. He yanked the stele from her belt. “Iz, Izzy, hold on—”

Jace, who had gathered up Alec’s fallen bow, looked like he was going to throw up or fall; Clary saw with dull surprise that Simon had his hand on Jace’s arm, his fingers digging in, as if he were holding Jace up.

Alec tore at the slashed fabric of Isabelle’s gear, ripping her trouser leg open to the knee. Clary stifled a cry. Isabelle’s leg was ribboned: it looked like pictures of shark bites Clary had seen, blood and pulped tissue surrounding deep indents.

Alec put his stele to the skin of her knee and drew an iratze, and then another an inch farther down. His shoulders were shaking, but his hand was steady. Clary wrapped her hand around Jace’s and squeezed. His was ice-cold.

“Izzy,” Alec whispered as the iratzes faded and sank into her skin, leaving white remnants behind. Clary remembered Hodge, how they had drawn healing rune after healing rune on him, but his wounds had been too great: the runes had faded, and he had bled out and died despite the runes’ power.

Alec looked up. The shape of his face was awkward, twisted; there was blood on his cheek: Isabelle’s, Clary thought. “Clary,” he said. “Maybe if you try—”

Simon suddenly stiffened. “We need to get out of here,” he said. “I can hear wings. There’s going to be more of them.”

Isabelle was no longer gasping. The bleeding from the slash in her leg had slowed, but Clary could see, with a sinking heart, that the wounds were still there, a puffed and angry red.

Alec rose, cradling his sister’s limp body in his arms, her black hair hanging down like a flag. “Go where?” he said harshly. “If we run, they’ll be on us—”
