“That’s the first time I’ve heard you call him your father and sound like that,” Clary said. “Usually you only say it about Valentine.”

She felt him sigh, and then his hand covered hers where it lay on his chest. His fingers were cool, long and slender, so familiar, she would have known them in the dark. “We might live here someday,” he said. “Together.”

She smiled, knowing he couldn’t see her, but unable to help it. “Think you can win me over with a fancy house?” she said. “Don’t get ahead of yourself, Jace. Jace Herondale,” she added, and wrapped her arms around him in the cold.

Alec sat at the edge of the roof, dangling his feet over the side. He supposed that if either of his parents came back to the house and looked up, they’d see him and he’d get shouted at, but he doubted Maryse or Robert would return soon. They’d been called to the Consul’s office after the meeting and were probably still there. The new treaty with the Fair Folk would be hammered out over the next week, during which they’d stay in Idris, while the rest of the Lightwoods went back to New York and celebrated the New Year without them. Alec would, technically, be running the Institute for that week. He was surprised to find that he was actually looking forward to it.

Responsibility was a good way to take your mind off other things. Things like the way Jocelyn had looked when her son had died, or the way Clary had stifled her silent sobs against the floor when she’d realized that they’d come back from Edom, but without Simon. The way Magnus’s face had looked, bleak with despair, as he’d said his father’s name.

Loss was part of being a Shadowhunter, you expected it, but that didn’t help the way Alec had felt when he’d seen Helen’s expression in the Council Hall as she’d been exiled to Wrangel Island.

“You couldn’t have done anything. Don’t punish yourself.” The voice behind him was familiar; Alec squeezed his eyes shut, trying to steady his breathing before he replied.

“How’d you get up here?” he asked. There was a rustle of fabric as Magnus settled himself down next to Alec at the edge of the roof. Alec chanced a sideways glance at him. He’d seen Magnus only twice, briefly, since they’d returned from Edom—once when the Silent Brothers had released them from quarantine, and once again today in the Council Hall. Neither time had they been able to talk. Alec looked him over with a yearning he suspected was poorly disguised. Magnus was back to his normal healthy color after the drained look he had had in Edom; his bruises were largely healed, and his eyes were bright again, glinting under the dimming sky.

Alec remembered throwing his arms around Magnus in the demon realm, when he’d found him chained up, and wondered why things like that were always so much easier to do when you thought you were about to die.

“I should have said something,” Alec said. “I voted against sending her away.”

“I know,” said Magnus. “You and about ten other people. It was overwhelmingly in favor.” He shook his head. “People get scared, and they take it out on anyone they think is different. It’s the same cycle I’ve seen a thousand times.”

“It makes me feel so useless.”

“You’re anything but useless.” Magnus tipped his head back, his eyes searching the sky as the stars began to make their appearances, one by one. “You saved my life.”

“In Edom?” Alec said. “I helped, but really—you saved your own life.”

“Not just in Edom,” Magnus said. “I was—I’m almost four hundred years old, Alexander. Warlocks, as they get older, they start to calcify. They stop being able to feel things. To care, to be excited or surprised. I always told myself that would never happen to me. That I’d try to be like Peter Pan, never grow up, always retain a sense of wonder. Always fall in love, be surprised, be open to being hurt as much as I was open to being happy. But over the last twenty years or so I’ve felt it creeping up on me anyway. There was nobody before you for a long time. Nobody I loved. No one who surprised me or took my breath away. Until you walked into that party, I was starting to think I’d never feel anything that strongly again.”

Alec caught his breath and looked down at his hands. “What are you saying?” His voice was uneven. “That you want to get back together?”

“If you want to,” Magnus said, and he actually sounded uncertain, enough that Alec looked at him in surprise. Magnus looked very young, his eyes wide and gold-green, his hair brushing his temples in wisps of black. “If you . . .”

Alec sat, frozen. For weeks he’d sat and daydreamed about Magnus saying these exact words, but now that Magnus was, it didn’t feel the way he’d thought it would. There were no fireworks in his chest; he felt empty and cold. “I don’t know,” he said.

The light died out of Magnus’s eyes. He said, “Well, I can understand that you—I wasn’t very kind to you.”

“No,” Alec said bluntly. “You weren’t, but I guess it’s hard to break up with someone kindly. The thing is, I am sorry about what I did. I was wrong. Incredibly wrong. But the reason I did it, that isn’t going to change. I can’t go through my life feeling like I don’t know you at all. You keep saying the past is the past, but the past made you who you are. I want to know about your life. And if you’re not willing to tell me about it, then I shouldn’t be with you. Because I know me, and I won’t ever be okay with it. So I shouldn’t put us both through that again.”

Magnus pulled his knees up to his chest. In the darkening twilight he looked gangly against the shadows, all long legs and arms and thin fingers sparkling with rings. “I love you,” he said quietly.

“Don’t—” Alec said. “Don’t. It’s not fair. Besides—” He glanced away. “I doubt I’m the first one who ever broke your heart.”

“My heart’s been broken more times than the Clave’s Law about Shadowhunters not engaging in romances with Downworlders,” Magnus said, but his voice sounded brittle. “Alec . . . you’re right.”

Alec cut his eyes sideways. He didn’t think he’d ever seen the warlock look so vulnerable.

“It’s not fair to you,” Magnus said. “I’ve always told myself I was going to be open to new experiences, and so when I started to—to harden—I was shocked. I thought I’d done everything right, not closed my heart off. And then I thought about what you said, and I realized why I was starting to die inside. If you never tell anyone the truth about yourself, eventually you start to forget. The love, the heartbreak, the joy, the despair, the things I did that were good, the things I did that were shameful—if I kept them all inside, my memories of them would start to disappear. And then I would disappear.”

“I . . .” Alec wasn’t sure what to say.

“I had a lot of time to think, after we broke up,” Magnus said. “And I wrote this.” He pulled a notebook out of the inside pocket of his jacket: just a very ordinary spiral-bound notebook of lined paper, but when the wind flapped it open, Alec could see that the pages were covered with thin, looping handwriting. Magnus’s handwriting. “I wrote down my life.”
