“Magnus—”

“Besides, Camille’s dead. He can’t do it again.”

“You know what I mean,” said Jace. “He won’t lie to you or mislead you or hide things from you or whatever it is you’re actually upset about.” He threw himself into a wingback leather chair and raised an eyebrow. “So?”

Magnus rolled onto his side. “What do you care if Alec’s miserable?”

“What do I care?” Jace said, so loudly that Chairman Meow sat bolt upright as if he’d been shocked. “Of course I care about Alec; he’s my best friend, my parabatai. And he’s unhappy. And so are you, by the look of things. Take-out containers everywhere, you haven’t done anything to fix up the place, your cat looks dead—”

“He’s not dead.”

“I care about Alec,” Jace said, fixing Magnus with an unswerving gaze. “I care about him more than I care about myself.”

“Don’t you ever think,” Magnus mused, pulling at a bit of peeling fingernail polish, “that the whole parabatai business is rather cruel? You can choose your parabatai, but then you can never un-choose them. Even if they turn on you. Look at Luke and Valentine. And though your parabatai is the closest person in the world to you in some ways, you can’t fall in love with them. And if they die, some part of you dies too.”

“How do you know so much about parabatai?”

“I know Shadowhunters,” said Magnus, patting the sofa beside him so that the Chairman leaped up onto the cushions and nudged at Magnus with his head. The warlock’s long fingers sank into the cat’s fur. “I have for a long time. You are odd creatures. All fragile nobility and humanity on one side, and all the thoughtless fire of angels on the other.” His eyes flicked toward Jace. “You especially, Herondale, for you have the fire of angels in your blood.”

“You’ve been friends with Shadowhunters before?”

“Friends,” said Magnus. “What does that mean, really?”

“You’d know,” said Jace, “if you had any. Do you? Do you have friends? I mean, besides the people who come to your parties. Most people are afraid of you, or they seem to owe you something or you slept with them once, but friends—I don’t see you having a lot of those.”

“Well, this is novel,” said Magnus. “None of the rest of your group has tried insulting me.”

“Is it working?”

“If you mean do I suddenly feel compelled to get back together with Alec, no,” said Magnus. “I have developed an odd craving for pizza, but that might be unrelated.”

“Alec said you do that,” said Jace. “Deflect questions about yourself with jokes.”

Magnus narrowed his eyes. “And I’m the only one who does that?”

“Exactly,” Jace said. “Take it from someone who knows. You hate talking about yourself, and you’d rather make people angry than be pitied. How old are you, Magnus? The real answer.”

Magnus said nothing.

“What were your parents’ names? Your father’s name?”

Magnus glared at him out of gold-green eyes. “If I wanted to lie on a couch and complain to someone about my parents, I’d hire a psychiatrist.”

“Ah,” said Jace. “But my services are free.”

“I heard that about you.”

Jace grinned and slid down in his chair. There was a pillow with a pattern of the Union Jack on the ottoman. He grabbed it and put it behind his head. “I don’t have anywhere to be. I can sit here all day.”

“Great,” Magnus said. “I’m going to take a nap.” He reached out for a crumpled blanket lying on the floor, just as Jace’s phone rang. Magnus watched, arrested midmotion, as Jace dug around in his pocket and flipped the phone open.

It was Isabelle. “Jace?”

“Yeah. I’m at Magnus’s place. I think I might be making some headway. What’s up?”

“Come back,” Isabelle said, and Jace sat up straight, the pillow tumbling to the floor. Her voice was tightly strained. He could hear the sharpness in it, like the off notes of a badly tuned piano. “To the Institute. Right away, Jace.”

“What is it?” he asked. “What’s happened?” And he saw Magnus sit up too, the blanket dropping from his hand.

“Sebastian,” Isabelle said.

Jace closed his eyes. He saw golden blood, and white feathers scattered across a marble floor. He remembered the apartment, a knife in his hands, the world at his feet, Sebastian’s grip on his wrist, those fathomless black eyes looking at him with dark amusement. There was a buzzing in his ears.

“What is it?” Magnus’s voice cut through Jace’s thoughts. He realized he was already at the door, the phone back in his pocket. He turned. Magnus was behind him, his expression stark. “Is it Alec? Is he all right?”

“What do you care?” said Jace, and Magnus flinched. Jace didn’t think he’d ever seen Magnus flinch before. It was the only thing that kept Jace from slamming the door on the way out.

There were dozens of unfamiliar coats and jackets hanging in the entryway of the Institute. Clary felt the tight buzzing of tension in her shoulders as she unzipped her own wool coat and hung it on one of the hooks that lined the walls.

“And Maryse didn’t say what this was about?” Clary demanded. The edges of her voice had been rubbed thin by anxiety.

Jocelyn had unwound a long gray scarf from around her neck, and barely looked as Luke took it from her to drape it on a hook. Her green eyes were darting around the room, taking in the gate of the elevator, the arched ceiling overhead, the faded murals of men and angels.

Luke shook his head. “Just that there’d been an attack on the Clave, and we needed to get here as quickly as possible.”

“It’s the ‘we’ part that concerns me.” Jocelyn wound her hair up into a knot at the back of her head, and secured it with her fingers. “I haven’t been in an Institute in years. Why do they want me here?”

Luke squeezed her shoulder reassuringly. Clary knew what Jocelyn feared, what they all feared. The only reason the Clave would want Jocelyn here was if there was news of her son.

“Maryse said they’d be in the library,” Jocelyn said. Clary led the way. She could hear Luke and her mother talking behind her, and the soft sound of their footsteps, Luke’s slower than they had once been. He hadn’t entirely recovered from the injury that had nearly killed him in November.

You know why you’re here, don’t you, breathed a soft voice in the back of her head. She knew it wasn’t really there, but that didn’t help. She hadn’t seen her brother since the fight at the Burren, but she carried him in some small part of her mind, an intrusive, unwelcome ghost. Because of me. You always knew I hadn’t gone away forever. I told you what would happen. I spelled it out for you.

Erchomai.

I am coming.

They had reached the library. The door was half-open, and a babble of voices spilled through. Jocelyn paused for a moment, her expression tight.

Clary put her hand on the doorknob. “Are you ready?” She hadn’t noticed till then what her mother was wearing: black jeans, boots, and a black turtleneck. As if, without thinking of it, she had put on the closest thing she had to fighting gear.
