" A girl clutched Magnus’s sleeve and gazed up at him, her false lashes dusted with silver glitter. “Don’t go in,” she whispered. “There’s a monster in there.”
I am a monster, Magnus thought. And monsters are his specialty.
He didn’t say it. Instead he said, “I don’t believe you,” and walked in. He meant it, too: the
Shadowhunters, even Alec, might believe Magnus was a monster, but Magnus didn’t believe it himself. He’d taught himself not to believe it even though his mother, the man he’d called his father, and a thousand others had told him it was true.
Magnus would not believe the girl in there was a monster either, no matter what she might look like to mundanes and Nephilim. She had a soul, and that meant she could be saved. "
