CITY OF GLASS

Looking aggrieved, Max stalked past them both, his book clutched to his chest. Simon felt a twinge of sympathy—it sucked to be old enough to want to know what was going on, but so young you were always dismissed. The boy shot him a look as he went past—a scared, suspicious glance. That’s the vampire, his eyes said.

“Come on.” Jace hustled Simon into the room, shutting and locking the door behind them. With the door closed the room was so dimly lit even Simon found it dark. It smelled like dust. Jace walked across the floor and threw open the curtains at the far end of the room, revealing a tall, single-paned picture window that gave out onto a view of the canal just outside. Water splashed against the side of the house just a few feet below them, under stone railings carved with a weather-beaten design of runes and stars.

Jace turned to Simon with a scowl. “What the hell is your problem, vampire?”

“My problem? You’re the one who practically dragged me out of there by my hair.”

“Because you were about to tell them that Clary never canceled her plans to come to Idris. You know what would happen then? They’d contact her and arrange for her to come. And I already told you why that can’t happen.”

Simon shook his head. “I don’t get you,” he said. “Sometimes you act like all you care about is Clary, and then you act like—”

Jace stared at him. The air was full of dancing dust motes; they made a shimmering curtain between the two boys. “Act like what?”

“You were flirting with Aline,” Simon said. “It didn’t seem like all you cared about was Clary then.”

“That is so not your business,” Jace said. “And besides, Clary is my sister. You do know that.”

“I was there in the faerie court too,” Simon replied. “I remember what the Seelie Queen said. The kiss that will free the girl is the kiss that she most desires.”

“I bet you remember that. Burned into your brain, is it, vampire?”

Simon made a noise in the back of his throat that he hadn’t even realized he was capable of making. “Oh, no you don’t. I’m not having this argument. I’m not fighting over Clary with you. It’s ridiculous.”

“Then why did you bring all this up?”

“Because,” Simon said. “If you want me to lie—not to Clary, but to all your Shadowhunter friends—if you want me to pretend that it was Clary’s own decision not to come here, and if you want me to pretend that I don’t know about her powers, or what she can really do, then you have to do something for me.”

“Fine,” Jace said. “What is it you want?”

Simon was silent for a moment, looking past Jace at the line of stone houses fronting the sparkling canal. Past their crenellated roofs he could see the gleaming tops of the demon towers. “I want you to do whatever you need to do to convince Clary that you don’t have feelings for her. And don’t—don’t tell me you’re her brother; I already know that. Stop stringing her along when you know that whatever you two have has no future. And I’m not saying this because I want her for myself. I’m saying it because I’m her friend and I don’t want her hurt.”

Jace looked down at his hands for a long moment without answering. They were thin hands, the fingers and knuckles scuffed with old calluses. The backs of them were laced with the thin white lines of old Marks. They were a soldier’s hands, not a teenage boy’s. “I’ve already done that,” he said. “I told her I was only interested in being her brother.”

“Oh.” Simon had expected Jace to fight him on this, to argue, not to just give up. A Jace who just gave up was new—and left Simon feeling almost ashamed for having asked. Clary never mentioned it to me, he wanted to say, but then why would she have? Come to think of it, she had seemed unusually quiet and withdrawn lately whenever Jace’s name had come up. “Well, that takes care of that, I guess. There’s one last thing.”

“Oh?” Jace spoke without much apparent interest. “And what’s that?”

“What was it Valentine said when Clary drew that rune on the ship? It sounded like a foreign language. Meme something—?”

“Mene mene tekel upharsin,” Jace said with a faint smile. “You don’t recognize it? It’s from the Bible, vampire. The old one. That’s your book, isn’t it?”

“Just because I’m Jewish doesn’t mean I’ve memorized the Old Testament.”

“It’s the Writing on the Wall. ‘God hath numbered thy kingdom, and brought it to an end; thou art weighed in the balance and found wanting.’ It’s a portent of doom—it means the end of an empire.”

“But what does that have to do with Valentine?”
