CITY OF GLASS

“Shut up!” Sebastian pushed down on the dagger, twisting the hilt. Jace arched backward with a scream, and agony burst like lightning behind his eyes. I’m going to die, he thought. I’m dying. This is it. He wondered if his heart had already been pierced. He couldn’t move, couldn’t breathe. He knew now what it must be like for a butterfly pinned to a board. He tried to speak, tried to say a name, but nothing came out of his mouth but more blood.

And yet Sebastian seemed to read his eyes. “Clary. I’d almost forgotten. You’re in love with her, aren’t you? The shame of your nasty incestuous impulses must nearly have killed you. Too bad you didn’t know she’s not really your sister. You could have spent the rest of your life with her, if only you weren’t so stupid.” He bent down, pushing the knife in harder, its edge scraping bone. He spoke in Jace’s ear, a voice as soft as a whisper. “She loved you, too,” he said. “Keep that in mind while you die.”

Darkness flooded in from the edges of Jace’s vision, like dye spilling onto a photograph, blotting out the image. Suddenly there was no pain at all. He felt nothing, not even Sebastian’s weight on him, as if he were floating. Sebastian’s face drifted over him, white against the darkness, the dagger raised in his hand. Something bright gold glittered at Sebastian’s wrist, as if he were wearing a bracelet. But it wasn’t a bracelet, because it was moving. Sebastian looked toward his hand, surprised, as the dagger fell from his loosened grasp and struck the mud with an audible sound.

Then the hand itself, separated from his wrist, thumped to the ground beside it.

Jace stared wonderingly as Sebastian’s severed hand bounced and came to rest against a pair of high black boots. The boots were attached to a pair of delicate legs, rising to a slender torso and a familiar face capped with a waterfall of black hair. Jace raised his eyes and saw Isabelle, her whip soaked with blood, her eyes fastened on Sebastian, who was staring at the bloody stump of his wrist with openmouthed amazement.

Isabelle smiled grimly. “That was for Max, you bastard.”

“Bitch,” Sebastian hissed—and sprang to his feet as Isabelle’s whip came slashing at him again with incredible speed. He ducked sideways and was gone. There was a rustle—he must have vanished into the trees, Jace thought, though it hurt too much to turn his head and look.

“Jace!” Isabelle knelt down over him, her stele shining in her left hand. Her eyes were bright with tears; he must seem pretty bad, Jace realized, for Isabelle to look like that.

“Isabelle,” he tried to say. He wanted to tell her to go, to run, that no matter how spectacular and brave and talented she was—and she was all those things—she was no match for Sebastian. And there was no way that Sebastian was going to let a little thing like getting his hand sliced off stop him. But all that came out of Jace’s mouth was a sort of gurgling noise.

“Don’t talk.” He felt the tip of her stele burn against the skin of his chest. “You’ll be fine.” Isabelle smiled down at him tremulously. “You’re probably wondering what the hell I’m doing here,” she said. “I don’t know how much you know—I don’t know what Sebastian’s told you—but you’re not Valentine’s son.” The iratze was close to finished; already Jace could feel the pain fading. He nodded slightly, trying to tell her: I know. “Anyway, I wasn’t going to come looking for you after you ran off, because you said in your note not to, and I got that. But there was no way I was going to let you die thinking you have demon blood, or without telling you that there’s nothing wrong with you, though honestly, how you could have thought anything so stupid in the first place—” Isabelle’s hand jerked, and she froze, not wanting to spoil the rune. “And you needed to know that Clary’s not your sister,” she said, more gently. “Because—because you just did. So I got Magnus to help me track you. I used that little wooden soldier you gave to Max. I don’t think Magnus would have done it normally, but let’s just say he was in an unusually good mood, and I may have told him Alec wanted him to do it—although that wasn’t strictly true, but it’ll be a while before he finds that out. And once I knew where you were, well, he’d already set up that Portal, and I’m very good at sneaking—”
