Cassandra Clare, City of Heavenly Fire

"As if we’d have sex in a cave surrounded by hordes of demons. This is reality, not your fevered imagination."

"she...let the blood spill down instead of tears."

"Can I tell you a boring science fact" she whispered. "I bet you didn't learn it in Shadowhunter history class."If you're trying to distract me from talking about my feelings, you're not being very subtle about it." He touched her face. "You know I make speeches. It's okay. You don't have to make them back. Just tell me you love me,"I'm not trying to distract you." She held up her hand and wiggles the fingers. "There are a hundred trillion cells in the human body," she said. "And every single one of the cells of my body loves you. We shed cells, and grow new ones, and my new cells love you more than the old ones, which is why I love you more every day than I did before. It's science. And when I die and they burn my body and I become ashes that mix with the air, and part of the ground and the trees and the stars, everyone who breathes air of sees the flowers that grow out of the ground or looks up at the stars will remember you and love you, because I love you that much," She smiled. "How was that for a speech?"

"Family isn't blood. It's the people who love you. The people who have your back."

"Aren't we forever?"

"It took courage to live an immortal life and not close off your heart and mind to any new experiences or new people. Because that which was new was almost always temporary. And that which was temporary broke your heart."

"And Nephilim—we tend to love very overwhelmingly. To fall in love only once, to die of grief over love—my old tutor used to say that the hearts of the Nephilim were like hearts of angels: They felt every human pain, and never healed."

"They sat in silence on the windowsill, their hands locked across the distance between them."

"I wish I had a parabatai," Emma said. "It's like someone who's your family, but because they want to be, not because they have to be."

"Clary," he said. "You're Clary. You're my best friend."

"Mundane education is regrettably prosaic," - Jace Lightwood-Herondale"

"Don’t carry the weight of the world on you Jace. It’s too heavy for even a Herondale to bear."

"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."

"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. Simon rolled quickly off Isabelle, who sat up, brushing herself off as if for lint. Simon sat up more slowly, trying to hold the torn edges of his shirt together. “Why are all my clothes on the floor?” Alec said.“I was trying to find something for Simon to wear,” Isabelle explained. “Maureen put him in leather pants and a puffy shirt because he was being her romance-novel slave.”“He was being her what?”“Her romance-novel slave,” Isabelle repeated, as if Alec were being particularly dense. Alec shook his head as if he were having a bad dream. “You know what? Don’t explain. Just—put your clothes on, both of you."

"Don't you think 'Mark is kind of a weird name for a Shadowhunter" Julian was saying as Emma approached. "I mean, if you really think about it. It's confusing. 'Put a Mark on me, Mark."

"He’s not feeling well,” Clary said, catching at Simon’s wrist. “We’re going.” “No,” Simon said. “No, I — I need to talk to him. To the Inquisitor." Robert reached into his jacket and drew out a crucifix. Clary stared in shock as he held it up between himself and Simon. “I speak to the Night’s Children Council representative, or to the head of the New York clan,” he said. “Not to any vampire who comes to knock at my door —“ Simon reached out and plucked the cross out of Robert’s hand. “Wrong religion,” he said."

"Jace broke off the kiss and stepped back with an exhale; before Clary could say anything, a chorus of sarcastic applause broke out from the nearby hill. Simon, Isabelle, and Alec waved at them. Jace bowed while Clary stepped back slightly sheepishly, hooking her thumbs into the belt of her jeans Jace sighed. "Shall we join our annoying, voyeuristic friends"Unfortunately, that's the only kind of friends we have."

"Value your parabatai," he said. "For it is a precious bond. All love is precious. It is why we do what we do. Why do we fight demons? Why are they not fit custodians of this world? What makes us better? It is because they do not build, but destroy. They do not love, but hate only. We are human and fallible, we Shadowhunters. But if we did not have the capability to love, we could not guard humans; we must love to guard them. My parabatai, he loved like few ever could love, with all and everything. I see you are like that too; it burns more brightly in you than the fire of Heaven"

"Herondales." Zachariah's voice was a breath, half laughter, half pain. "I had almost forgotten. No other family does so much for love, or feels so much guilt for it. Don't carry the weight of the world on you, Jace. It's too heavy for even a Herondale to bear."

"Every time I think I'm missing a piece of me, you give it back."
