“nothing says 'I love you' like reducing yourself to a smoldering pile of ashes”

“I'd always hoped that when i said 'I Love You' to a girl, she'd say 'I Know' like Leia did to Han in Return Of The Jedi”

“You kindled me, heap of ashes that I am, into fire. He had wondered once why love was always phrased in terms of burning. The conflagration in his own veins, now, gave the answer.”

“Whoever loves you now—and you must also love yourself—will love the truth of you.”

“And I would do it again. I love you, Jace Wayland-Herondale-Lightwood-whatever you want to call yourself. I don't care. I love you and I will always love you, and pretending it could be any other ways is just a waste of time.”

“The moment the door closed behind him, Tessa was in Will's arms, her hands locked about his neck. "Oh, by the Angel," she said. "That was mortifying." Will slid his hands into her hair and was kissing her, kissing her eyelids and her cheeks and then her mouth, quickly but with fervor and concentration, as if nothing could be more important. "Listen to you," he said. "You said 'by the angel.' Like a Shadowhunter." He kissed the side of her mouth. "I love you. God, I love you. I waited so long to say it.”

“They say you cannot love two people equally at once,” she said. “And perhaps for others that is so. But you and Will—you are not like two ordinary people, two people who might have been jealous of each other, or who would have imagined my love for one of them diminished by my love of the other. You merged your souls when you were both children. I could not have loved Will so much if I had not loved you as well. And I could not love you as I do if I had not loved Will as I did.”
