Cassandra Clare, City of Heavenly Fire

"Isabelle!" he called again. "Let down your raven hair!'"Oh my God," Clary muttered. "There was something in that blood Raphael gave you, wasn't there? I'm going to kill him."

"Its your decision, Simon Lewis," said Magnus. "Remain in the existence you have, go to college, study music, get married. Live your life. Or---you can have an uncertain life of shadows and dangers. You can have the joy of reading the stories of incredible happenings, or you can be part of the story."The choice is up to you"

"But I have made a study of Shadowhunters now, over the past century, and let me tell you that we are more human than most human beings. When our hearts break, they break into shards that cannot be easily fit back together. I envy mundanes their resilience sometimes."

"I think,” Jace said, “that you don’t want to tell your secrets, so you decided to break up with Alec because..."

"Shapes began to appear in the mist as it thickened. Clary saw herself and Simon as children, holding hands, crossing a street in Brooklyn,; she had barrettes in her hair and Simon was adorably rumpled, his glasses sliding off his nose. There they were again, throwing snowballs in Prospect Park; and at Luke's farmhouse, tanned from summer, hanging upside down from tree branches. She saw them in Java Jones, listening to Eric's terrible poetry, and on the back of a flying motorcycle as it crashed into a parking lot, with Jace there, looking at them, his eyes squinted against the sun. And there was Simon with Isabelle, his hands curved around her face, kissing her, and she could see Isabelle as Simon saw her: fragile and strong, and so, so beautiful. And there was Valentine's ship, Simon kneeling on Jace, blood on his mouth and shirt, and blood at Jace's throat, and there was the cell in Idris, and Hodge's weathered face, and Simon and Clary again, Clary etching the Mark of Cain onto his forehead. Maureen, and her blood on the floor, and her little pink hat, and the rooftop in Manhattan where Lilith had raised Sebastian, and Clary was passing him a gold ring across a table, and an Angel was rising out of a lake before him and he was kissing Isabelle..."

"Mortals dies." said Catarina. "You've always known that, and yet you've loved them before."Not," Magnus said, "like this."Catarina inhaled in surprise. "Oh," she said. "Oh..." She picked up her drink. "Magnus," she said tenderly. "you are impossibly stupid."He narrowed his eyes at her. "Am I"If that's the way you feel, you should be with him," she said. "Think of Tessa. Did you learn nothing from her? About what loves are worth the pain of losing them?"

"Goodness, that stuff rips like paper,” she exclaimed, reaching to pull her tank top off. She was halfway through the action when the door opened and Alec walked into the room.“Izzy, are you—” he began. His eyes flew wide, and he backed up fast enough to smack his head into the wall behind him. “What is he doing here?”Isabelle tugged her tank top back down and glared at her brother. “You don’t knock now?”“It—It’s my bedroom!” Alec spluttered. He seemed to be deliberately trying not to look at Izzy and Simon, who were indeed in a very compromising position."

"And I suppose you know who Magnus’ father is?” Luke said.“I paid a lot of money once to find it out,” Raphael said."

"Simon," said a voice at his shoulder, and he turned to see Izzy, her face a pale smudge between dark hair and dark cloak, looking at him, her expression half-angry, half-sad. "I guess this is the part where we say goodbye?"

"Wherever Jordan's going - and I do believe we all go somewhere - think of it as the light that will bring him home."

"You couldn’t make someone love you with a rune, and you couldn’t assuage grief with it either. So much magic, Clary thought, and nothing to mend a broken heart."

"I knew a girl, once, immortal like me-"And she was with someone mortal" said Alec. "What happened"He died," Magnus said. There was a finality to the way he said it that spoke of a deeper grief than words could paint."

"And she wept as well for the others lost in the Dark War, and she wept for her mother and the loss she had endured, and she wept for Emma and the Blackthorns, remembering how they had fought back tears when she had told them that she had seen Mark in the tunnels of Faerie, and how he belonged to the Hunt now, and she wept for Simon and the hole in her heart where he had been, and the she would miss him every day until she died, and she wept for herself and the changes that had been wrought in her, because sometimes even change for the better felt like a little death."

"As long as there is love and memory, there is no true loss."

"He remembered Tessa weeping in his arms in Paris, and thinking that he had never known the loss she felt, because he had never loved like she had, and that he was afraid that someday he would, and like Tessa he would lose his mortal love. And that it was better to be the one who died than the one who lived on. He had dismissed that, later, as a morbid fantasy, and had not remembered it again until Alec."

"Clary saw him take Mark's hand; he pressed his witchlight into the boy's palm, where it flickered, and then resumed its steady glow. 'Take this with you,' said Jace, 'for it can be dark in the land under the hill, and the years very long."

"Temper us in fire, and we grow stronger. When we suffer, we survive."

"Surely, she was too young to have so many ghosts."

"You shouldn't do that. Not to your child. You should-carry your own burdens."

"We find in our children our own selves again, who might be made better than we are."
