1. “I know you feel inhuman, and as if you are set apart, away from life and love, but... I promise you, the right man won't care.” - Cassandra Clare
2. “Jem shook his head. "You bit de Quincey" he said. "You fool. He's a VAMPIRE""I had no choice" said Will " He was choking me""I know" Jem said. " But really Will, AGAIN?” - Cassandra Clare
3. “A sort of good-bye without saying good-bye," he said. "It is a reference to a passage in the Bible. 'And Mizpah, for he said, the Lord watch between me and thee when we are absent one from another.” - Cassandra Clare
4. “She smiled. Her skin looked whiter than he recalled, and dark spidery veins were beginning to show beneath its surface. Her hair was still the color of spun silver and her eyes were still green as a cat’s. She was still beautiful. Looking at her, he was in London again. He saw the gaslight and smelled the smoke and dirt and horses, the metallic tang of fog, the flowers in Kew Gardens. He saw a boy with black hair and blue eyes like Alec’s, heard violin music like the sound of silver water. He saw a girl with long brown hair and a serious face. In a world where everything went away from him eventually, she was one of the few remaining constants.And then there was Camille.” - Cassandra Clare
5. “Will: "Nice place to live, isn't it? Let's hope they left something behind other than filth. Forwarding addresses, a few severed limbs, a prostitute or two ..."Jem: "Indeed. Perhaps, if we're fortunate, we can still catch syphilis." "Or demon pox," Will suggested cheerfully, trying the door under the stairs.” - Cassandra Clare
6. “Do you think Charlotte will let me handle the investigation?""Do you think you can be trusted in Downworld? The gaming hells, the dens of magical vice, the women of loose morals..." Will smiled the way Lucifer might have smiled, moments before he fell from heaven. "Would tomorrow be to early to start looking, do you think?Jem sighed. 'Do what you like, William. You always do.” - Cassandra Clare
7. “She smiled at him. “How did you know just what I’d want to see?”“How could I not?” he said. “When I think of you, and you are not there, I see you in my mind’s eye always with a book in your hand.” He looked away from her as he said it, but not before she caught the slight flush on his cheekbones. He was so pale, he could never hide even the least blush, she thought — and was surprised how affectionate the thought was.” - Cassandra Clare
8. “We’re Nephilim. Every one of our life’s passages has some mystical component — our births, our deaths, our, marriages, everything has a ceremony and a rune. There is one as well if you wish to become someone’s parabatai. It’s no small commitment.” - Cassandra Clare
9. “I can offer you my life, but it is a short life; I can offer you my heart, though I have no idea how many more beats it shall sustain” - Cassandra Clare

13. “Trains are great dirty smoky things," said Will. "You won't like it." Tessa was unmoved. "I won't know if I like it until I try it, will I?"

"But think how entertaining for sightseers," said Tessa, and she saw Jem duck his head to hide the quick flash of his grin.” - Cassandra Clare
14. “I played it for my bride, and one day you will play for yours.” - Cassandra Clare
15. “But I will never have a bride.” - Cassandra Clare
16. “Reparations,” said Jem very suddenly, setting down the pen he was holding.Will looked at him in puzzlement. “Is this a game? We just blurt out whatever word comes next to mind? In that case mine is ‘genuphobia’. It means an unreasonable fear of knees.”“What’s the word for a perfectly reasonable fear of annoying idiots?” inquired Jessamine.” - Cassandra Clare
17. “You speak of sacrifice, but it is not my sacrifice I offer. It is yours I ask of you," he went on. "I can offer you my life, but it is a short life; I can offer you my heart, though I have no idea how many more beats it shall sustain. But I love you enough to hope that you wil not care that I am being selfish in trying to make the rest of my life - whatever length - happy, by spending it with you. I want to be married to you, Tessa. I want it more than I have ever wanted anything else in my life." He looked up at her through the veil of silvery hair that fell over his eyes. "That is," he said shyly, "if you love me, too.” - Cassandra Clare
18. “It is the mundanes who look at me and see something they do not understand—a boy who is not quite white and not quite foreign either.""Just as I am not human, and not demon either," Tessa said softly.His eyes softened. "You are human," he said. "Never think you are not. I have seen you with your brother; I know how you care for him. If you can feel hope, guilt, sorrow, love—then you are human.” - Cassandra Clare
19. “He began it,” Cecily said, jerking her chin at Will, though she knew it was pointless. Jem, Will’s parabatai, treated her with the distant sweet kindness reserved for the little sisters of one’s friends, but he would always side with Will. Kindly, but firmly, he put Will above everything else in the world.Well, nearly everything.” - Cassandra Clare
20. “He touched her as he usually touched his beloved violin, with a soft and urgent grace that left her breathless.” - Cassandra Clare
21. “He made it very clear that he didn’t want me here,” she said at last. “That my remaining at the Institute is not the happy chance I thought it was. Not in his view.” “And after I just finished telling you why you should consider him family,” Jem said, a bit ruefully. “No wonder you looked as if I’d just told you something awful just happened.” “I’m sorry,” Tessa whispered. “Don’t be. It’s Will who ought to be sorry.” Jem’s eyes darkened. “We shall throw him out onto the streets,” he proclaimed. “I promise you he’ll be gone by morning.” Tessa started and sat upright. “Oh – no, you can’t mean that─” He grinned. “Of course I don’t. But you did feel better for a moment there, didn’t you?” - Cassandra Clare
22. “He flushed, the colour dark against his pale skin. 'I mean. Tessa Gray, will you do me the honour of becoming my wife?' Jem...” - Cassandra Clare
23. “You bit de Quincey," he said. "You fool. He's a vampire. You know what it means to bite a vampire." "I had no choice," said Will. "He was choking me.""I know," Jem said. "But really, Will. Again?” - Cassandra Clare
24. “This...this...thing?""A parsnip?" Jem suggested"A parsnip planted in satan's own garden," said Will. He glanced about. "I dont suppose there's a dog I could feed it to?""There dont seem to be any pets about," Jem-who loved animals, even the inglorious and ill-tempered Church-observed."Probably all poisened by parsnips," said Will.” - Cassandra Clare
25. “I love you. And I don't want to lose you.” - Cassandra Clare
26. “You are home for me now." --Jem to Tessa” - Cassandra Clare
27. “What are you doing following me around the back streets of London, you little idiot?” Will demanded, giving her arm a light shake.Cecily’s eyes narrowed. “This morning it was cariad (note: Welsh endearment, like ‘darling’ or ‘love’), now it’s idiot.”“Oh, you’re using a Glamour rune. There’s one thing to declare, you are not afraid of anything when you live in the country. But this is London.”“I’m not afraid of London,” Cecily said defiantly.Will leaned closer, almost hissing in her ear *and said something very complicated in Welsh*She laughed. “No, it wouldn’t do you any good to tell me to go home. You are my brother, and I want to go with you.”Will blinked at her words.You are my brother, and I want to go with you.It was the sort of thing he was used to hearing Jem say.Although Cecily was unlike Jem in every other conceivable possible way, she did share one quality with him. Stubbornness. When Cecily said she wanted something, it did not express an idle desire, but an iron determination.“Do you even care where I’m going?” he said. “What if I were going to hell?”“I’ve always wanted to see hell,” Cecily said. “Doesn’t everyone?”“Most of us spend our time trying to stay out of it, Cecily. I’m going to an ifrit den, if you must know, to purchase drugs from vile, dissolute criminals. They may clap eyes on you, and decide to sell you.”“Wouldn’t you stop them?”“I suppose it would depend on whether they cut me a part of the profit.”She shook her head. “Jem is your parabatai,” she said. “He is your brother, given to you by the Clave, but I am your sister by blood. Why would you do anything for him, but you only want me to go home?”“How do you know the drugs are for Jem?” Will said.“I’m not an idiot, Will.”“No, more’s the pity. Jem- Jem is like the better part of me. I would not expect you to understand. I owe him. I owe him this.”“So what am I?” Cecily said.Will exhaled, too desperate to check himself. “You are my weakness.”“And Tessa is your heart,” she said, not angrily, but thoughtfully. “I am not fooled. As I told you, I’m not an idiot. And more’s the pity for you, although I suppose we all want things we can’t have.”“Oh,” said Will, “and what do you want?”“I want you to come home.” A strand of black hair was stuck to her cheek by the dampness, and Will fought the urge to pull her cloak closer about her, to make her safe as he had when she was a child.“The Institute is my home,” Will sighed, and leaned his head against the stone wall. “I can’t stand out her arguing with you all evening, Cecily. If you’re determined to follow me into hell, I can’t stop you.”“Finally,” she said provingly. “You’ve seen sense. I knew you would, you’re related to me.”Will fought the urge to shake her.“Are you ready?”She nodded, and he raised his hand to knock on the door.” - Cassandra Clare
28. “Will’s eyes met Tessa’s as she came closer, almost tripping again over the torn hem of her gown. For a moment, they were in perfect understanding. Jem was what they could still look each other straight in the eye about. On the topic of Jem, they were both fierce and unyielding. Tessa saw Will’s hand tighten on Jem’s sleeve. “She’s here,” he said.Jem’s eyes opened slowly. Tessa fought to keep the look of shock from her face. His pupils were blown out, his irises a thin ring of silver around the black. “Ni shou shang le ma, quin ai de?” he whispered.” - Cassandra Clare
29. “[Jem] 'It will help you sleep.''All I’ve been doing is sleeping!' [Tessa]'And very amusing it is to watch, said Jem. 'Did you know you twitch your nose when you sleep, like a rabbit?''I do not,' she said, with a whispered laugh.'You do,' he said. 'Fortunately, I like rabbits.” - Cassandra Clare
30. “That the wall is coming down.” - Cassandra Clare
31. “You cannot reduce the situation to worm jokes, Will. This is Gabriel and Gideon’s father we’re discussing.”“We’re not just discussing him; we’re chasing him through an ornamental sculpture garden because he’s turned into a worm.” - Cassandra Clare
32. “Change is no loss, Will. Not always.” - Cassandra Clare
33. “All my life, since I came to the Institute, you were the mirror of my soul. I saw the good in me in you. In your eyes alone I found grace. When you are gone from me, who will see me like that?” - Cassandra Clare
34. “I don't know how to live in the world as a Shadowhunter without Will. I don't think i even want to. I am still a parabatai, but my other half is gone.” - Cassandra Clare
35. “I should have known what you would do,” Jem said in a low voice. “I always know what you will do. I should have known you would put your hands into the fire.”“And I should have known you would throw that packet away,” said Will, without rancor. “It was—it was a madly noble thing to do. I understand why you did it.”“I was thinking of Tessa.” Jem drew his knees up and rested his chin on them, then laughed softly. “Madly noble. Isn’t that meant to be your area of expertise? Suddenly I am the one who does ridiculous things and you tell me to stop?”“God,” said Will. “When did we change places?”The firelight played over Jem’s face and hair as he shook his head. “It is a very strange thing, to be in love,” he said. “It changes you.”Will looked down at Jem, and what he felt, more than jealousy, more than anything else, was a wistful desire to commiserate with his best friend, to speak of the feelings he held in his heart. For were they not the same feelings? Did they not love the same way, the same person? But, “I wish you wouldn’t risk yourself,” was all he said.Jem stood up. “I have always wished that about you.”Will raised his eyes, so drowsy with sleep and the tiredness that came with healing runes that he could see Jem only as a haloed figure of light. “Are you going?”“Yes, to sleep.” Jem touched his fingers lightly to Will’s healing hands. “Let yourself rest, Will.” - Cassandra Clare
36. “His eyes went soft and silver as she spoke. “Zhe shi jie shang, wo shi zui ai ne de,” he whispered.She understood it. In all the world, you are what I love the most.” - Cassandra Clare
37. “Zhe shi jie shang, wo shi zui ai ne de. In all the world, you are what I love the most.” - Cassandra Clare
38. “Wo men shi jie bai xiong di-we are more than brothers, Will.” - Cassandra Clare
39. “If there is a life after this one", he said, "let me meet you in it, James Carstairs.” - Cassandra Clare
40. “I think there is hope for you yet, Will Herondale.I will try to learn how to have it, without you to show me. Tessa, Jem said. She knows despair, and hope as well. you can teach each other. Find her, Will, and tell her that I loved her always. My blessings, for all that it is worth, is on you both.” - Cassandra Clare
41. “Gibberish?" Jem suggested "Pornographic?" said Will at the same time."Could be both," said Will. "Haven't you ever heard of pornographic gibberish before?” - Cassandra Clare
42. “She did not belong to Will-she was too much herself to belong to anyone, even Jem-but she belonged with them, and silently he cursed the Consul for not seeing it.” - Cassandra Clare
43. “I will still be in some part the Jem you knew, and I will see you with the eyes of my heart.” - Cassandra Clare
44. “What I do know is that if we are born again, I will meet you in another life, and if there is a river, you will wait on the shores for me to come to you, so that we can cross together.” - Cassandra Clare
45. “This was a voice that drew out memories stretched thin by years of recollection, like paper unfolded and refolded too many times. A voice that brought back, like a wave, the memory of another time on this bridge, a night so long ago, everything black and silver and the river rushing away under her feet...” - Cassandra Clare
46. “Hay más en la vida que no morir, –dijo. –Mira la forma en que vives, Will. Brillas tanto como una estrella. Había estado tomando solo la droga necesaria para mantenerme con vida pero no suficiente como para mantenerme bien. Un poco más de ella antes de las batallas, tal vez, me da energía, sin embargo, una media vida, el gris crepúsculo de una vida. –¿Pero has cambiado tu dosis ahora? ¿Ha sido desde el compro- miso? –Demandó Will. –¿O es por Tessa? –No puedes culparla por esto. Fue mi decisión. Ella no sabe sobre esto. –Ella quiere que vivas, James.” - Cassandra Clare
47. “There's nothing you could have done that would cause me to cease loving either of you. Will is myself, my own soul, and if I am not to have the keeping of your heart, then there is not other I would rather have that honor.” - Cassandra Clare
48. “Will closed his eyes. He could not hear Jem go, not anymore; he did not want to know the moment when he left and Will was alone, did now want to know when his first day as a Shawdowhunter without a parabatai truly began. And if the place over his heart, where his parabatai rune had been, flared up with a sudden burning pain as the door closed behind Jem, Will told himself it was only a stray ember from the fire.” - Cassandra Clare
49. “I want it to stop," he said. "Sophie says everyone is still searching for a cure for me. I know I gave Will my permission, but I want everyone to cease looking now, Charlotte. It is over.” - Cassandra Clare
50. “As metal rang on metal, some inner part of Jem, some part that had been lost without his even knowing it was lost, felt the pleasure of fighting together with Will one last time.” - Cassandra Clare
51. “ーEscribí algo para ti, ーla corrigió con una sonrisa y comenzó a tocar. Ella escuchó emocionada; comenzó lento, sencillo, su control sobre el arco producía un sonido armónico. La melodía la lleno tan fresca y dulce como el agua, tan esperanzadora y adorable como un amanecer. Miró a sus dedos fascinada por el movimiento tan exquisito que hacia que las notas salieran del violín. El sonido se volvió mas profundo conforme el arco se movía mas rápido, el antebrazo de Jem se desplazaba hacia adelante y atrás, su delgado cuerpo parecía difuminarse con el movimiento de su hombro. Sus dedos se deslizaban cuidadosamente arriba y abajo, el tono de la música profundizó, como nubes de tormenta reuniéndose en un horizonte brillante, un río que se convertía en torrente. Las notas se estrellaban a sus pies aumentando el sonido, el cuerpo entero de Jem parecía moverse en sintonía con los sonidos que emanaban del instrumento, a pesar de que ella sabia que sus pies se encontraban firmes en el suelo. Su corazón encontró la paz con la música, los ojos de Jem estaban cerrados, las comisuras de sus labios mostraban un gesto de dolor. Una parte de ella quería correr a sus pies, rodearlo con sus brazos; la otra otra parte no quería que se detuviera la música, el hermoso sonido de él. Era como si él hubiera tomado su arco utilizándolo como un pincel para pintar, creando un lienzo en el cual su alma se muestra claramente. Cuando las ultimas notas se alzaron más y más alto, llegando a tocar el paraíso, Tessa estuvo consciente de que su rostro estaba húmedo, pero no fue hasta que la ultima nota dejo de sonar y él bajo el violín cuando se dio que estaba llorando.” - Cassandra Clare
