“What do you want?""Just coffee. Black - like my soul.”

“Just coffee. Black—like my soul.”

“They’re not hideous,” said Tessa. Will blinked at her. “What?” “Gideon and Gabriel,” said Tessa. “They’re really quite good-looking, not hideous at all.” “I spoke,” said Will, in sepulchral tones, “of the pitch-black inner depths of their souls.” Tessa snorted. “And what color do you suppose the inner depths of your soul are, Will Herondale?” “Mauve,” said Will.”

I should want to protect you"—he laughed soundlessly without any humor—"to protect you from the sort of boys who want to do with you exactly what I want to do."Clary's breath caught. "You said you just wanted to be my brother from now on.""I lied," he said. "Demons lie, Clary.

You don't even know what's wrong with you, but you're bleeding to death slowly inside. That's what it's like, just being your brother.""But Aline—""I had to try. And I did." His voice was lifeless. "But God knows, I don't want anyone but you. I don't even want to want anyone but you." He reached out, trailed his fingers lightly through her hair, fingertips brushing her cheek. "Now at least I know why."Clary's voice had sunk to a whisper. "I don't want anyone but you, either.”

“It doesn’t change what we are to each other. It’s like there’s always been a piece of my soul missing, and it’s inside you, Clary.”
