It's like a conversation between two people.

all I need is blue skies…and you

Underneath the moon, underneath the stars
Here's a little heart for you
Up above the world, up above it all
Here's a hand to hold on to

Always turning back to you
'til you never let me down
Loving your illusions
Staring at a crooked crown

Jars of Clay-Headphones

I don’t have to hear it, if I don’t want to I can drown this out,  pull the curtains down on you
It’s a heavy world, it’s too much for me to care
If I close my eyes, it’s not there
With my headphones on, with my headphones on
With my headphones on, with my headphones on

I never saw it happening, I'd given up and given in 
I just couldn't take the hurt again 
What a feeling 
I didn't have the strength to fight 
suddenly you seemed so right 
Me and you, what a feeling

Another blow came, and this time the hinges gave way and the door flew outward. It would have knocked Jace over if he hadn't moved so fast that Clary barely saw it; suddenly he was on the top stair, the blade burning in his hand like a fallen star. She saw Jace look at her and shout something, but she couldn't hear him over the roar of the gigantic creature that burst from the shattered door, making straight for him. She flattened herself against the wall as it passed in a wave of heat and stink— and then its axe was flying, whipping through the air, slicing toward Jace's head. He ducked, and it thunked heavily into the banister, biting deep.
Jace laughed.

City of Bones, chapter 6; Forsaken

Jace sucked a breath in, and she realized he had never expected her to say what she'd just said, not in a million years. The look on his face said as much.

She scrambled to regain her composure. "Jace, I'm sorry, I didn't mean—"

"No. You're not sorry. Don't be sorry." He moved toward her, almost tripping over his feet—Jace, who never stumbled, never tripped over anything, never made an ungraceful move. His hands came up to cup her face; she felt the warmth of his fingertips, millimeters from her skin; knew she ought to pull away, but stood frozen, staring up at him. "You don't understand," he said. His voice shook. "I've never felt this way about anyone. I didn't think I could. I thought—the way I grew up—my father—"

"To love is to destroy," she said numbly. "I remember."

"I thought that part of my heart was broken," he said, and there was a look on his face as he spoke as if he were surprised to hear himself saying these words, saying my heart. "Forever. But you—"

"Jace. Don't." She reached up and covered his hand with hers, folding his fingers into her own. "It's pointless."

"That's not true." There was desperation in his voice. "If we both feel the same way—"

"It doesn't matter what we feel. There's nothing we can do." She heard her voice as if a stranger were speaking: remote, miserable. "Where would we go to be together? How could we live?"

"We could keep it a secret."

City of Ashes, chapter 9; And Death Shall Have No Dominion

She was clutching her sketchpad, her bright hair escaping out of its braids. He leaned against the door frame, ignoring the kick of adrenaline the sight of her produced. He wondered why, not for the first time. Isabelle used her beauty like she used her whip, but Clary didn't know she was beautiful at all. Maybe that was why.

He could think of only one reason for her to be there, though it made no sense after what he'd said to her. Words were weapons, his father had taught him that, and he'd wanted to hurt Clary more than he'd ever wanted to hurt any girl. In fact, he wasn't sure he had ever wanted to hurt a girl before. Usually he just wanted them, and then wanted them to leave him alone.

City of Bones, chapter 18; The Mortal Cup

She looked at him silently for a moment. He needed a haircut. His hair curled the way vines did when they got too long, in looping tendrils, the color of white gold in the moonlight. The scars on his face and throat looked like they had been etched there with metallic ink. He was beautiful, she thought miserably, beautiful and there was nothing there in him, not an expression, not a slant of cheekbone or shape of jaw or curve of lips that bespoke any family resemblance to herself or her mother at all. He didn't even really look like Valentine.

"What?" he said. "Why are you looking at me like that?"

She wanted to throw herself into his arms and sob at the exact same time that she wanted to pound on him with her fists. Instead, she said, "If it weren't for what happened in the faerie court, Simon would still be alive."

He reached down and savagely yanked a hunk of grass out of the ground. Dirt still clung to the roots. He tossed it aside. "We were forced to do what we did. It's not as if we did it for fun, or to hurt him. Besides," he said, with the ghost of a smile, "you're my sister."

"Don't say it like that—"

"What, 'sister'?" He shook his head. "When I was a little kid, I realized that if you say any word over and over fast enough, it loses all its meaning. I'd lie awake saying the words over and over to myself—'sugar,' 'mirror,' 'whisper,' 'dark.' 'Sister,' " he said, softly. "You're my sister."

"It doesn't matter how many times you say it. It'll still be true."

"And it doesn't matter what you won't let me say, that'll still be true too."

City of Ashes, Chapter 10; A Fine and Private Place

His gaze was fixed on the green shrub they'd been sitting beside, with its dozens of shiny closed buds. She started to ask him what she was supposed to be looking at, but he held up a hand to forestall her. His eyes were shining. "Wait," he said.

The leaves on the shrub hung still and motionless. Suddenly one of the tightly closed buds began to quiver and tremble. It swelled to twice its size and burst open. It was like watching a speeded-up film of a flower blooming: the delicate green sepals opening outward, releasing the clustered petals inside. They were dusted with pale gold pollen as light as talcum.

"Oh!" said Clary, and looked up to find Jace watching her. "Do they bloom every night?"

"Only at midnight," he said. "Happy birthday, Clarissa Fray."

She was oddly touched. "Thank you."

"I have something for you," he said. He dug into his pocket and brought out something, which he pressed into her hand. It was a gray stone, slightly uneven, worn to smoothness in spots.

"Huh," said Clary, turning it over in her fingers. "You know, when most girls say they want a big rock, they don't mean, you know, literally a big rock."

"Very amusing, my sarcastic friend. It's not a rock, precisely. All Shadowhunters have a witchlight rune-stone."

"Oh." She looked at it with renewed interest, closing her fingers around it as she'd seen Jace do in the cellar. She wasn't sure, but she thought she could see a glint of light peeking out through her fingers.

"It will bring you light," said Jace, "even among the darkest shadows of this world and others."

City of Bones, chapter 17; The Midnight Flower

She could see why they were called the Fair Folk, for they were fair indeed with their pale lovely faces, their wings of lilac and gold and blue—how could she have believed Jace that they meant to harm her? The music that had jarred her ears at first now sounded only sweet. She felt the urge to toss her own hair and to move her own feet in the dance. The music told her that if she did that, she too would be so light that her feet would barely touch the earth. She took a step forward—

And was jerked back by a hand on her arm. Jace was glaring at her, his golden eyes bright as a cat's. "If you dance with them," he said in a low voice, "you'll dance until you die."

Clary blinked at him. She felt as if she'd been pulled out of a dream, groggy and half-awake. Her voice slurred when she spoke. "Whaaat?"

Jace made an impatient noise. He had his stele in his hand; she hadn't seen him take it out. He gripped her wrist and inscribed a quick, stinging Mark onto the skin of her inner arm. "Now look."

She looked again—and froze. The faces that had seemed so lovely to her were still lovely, yet behind them lurked something vulpine, almost feral. The girl with the pink and blue wings beckoned, and Clary saw that her fingers were made of twigs, budded with closed leaves. Her eyes were entirely black, without iris or pupil. The boy dancing next to her had poison green skin and curling horns twisting from his temples. When he turned in the dance, his coat fell open and Clary saw that beneath it, his chest was an empty rib cage. Ribbons were woven through his bare rib bones, possibly to make him look more festive. Clary's stomach lurched.

City of Ashes, Part Two; The Gates of Hell, chapter 8; The Seelie Court

She spun and kicked in the black water. Terror gripped her, terror of the blind darkness and of the depths of the river, the millions of tons of water all around her, pressing in on her, choking out the air in her lungs. She couldn't tell which way was up or which direction to swim. She could no longer hold her breath. She sucked in a lungful of filthy water, her chest bursting with the pain, stars exploding behind her eyes. In her ears the sound of rushing water was replaced by a high, sweet, impossible singing. I'm dying, she thought in wonder. A pair of pale hands reached out of the black water and drew her close. Long hair drifted around her. Mom, Clary thought, but before she could clearly see her mother's face, the darkness closed her eyes.

City of Ashes; chapter 16: A Stone of the Heart

"Stop it," she said. "Stop being like that."

His smile widened. "Like what?"

"If you're angry, just say it. Don't act like nothing ever touches you. It's like you never feel anything at all."

Falling in Love-Falling Up

“Sometimes I close my eyes/Sometimes I let my hunger rise/I think of all you are, you are the love of my life”

Scene:

“I don’t want anyone but you, either.”
She was rewarded by the catch in his breathing. Slowly he drew himself up onto his elbows. Now he was looking down at her, and his expression had changed—there was a look on his face she’d never seen before, a sleepy, almost deadly light in his eyes. He let his fingers trail down her cheek to her lips, outlining the shape of her mouth with the tip of a finger. “You should probably,” he said, “tell me not to do this.”
She said nothing. She didn’t want to tell him to stop. She was tired of saying no to Jace—of never letting herself feel what her whole heart wanted her to feel. Whatever the cost.
He bent down, his lips against her cheek, brushing it lightly—and still that light touch sent shivers through her nerves, shivers that made her whole body tremble. “If you want me to stop, tell me now,” he whispered. When she still said nothing, he brushed his mouth against the hollow of her temple. “Or now.” He traced the line of her cheekbone. “Or now.” His lips were against hers. “Or—”
But she had reached up and pulled him down to her, and the rest of his words were lost against her mouth. He kissed her gently, carefully, but it wasn’t gentleness she wanted, not now, not after all this time, and she knotted her fists in his shirt, pulling him harder against her. He groaned softly, low in his throat, and then his arms circled her, gathering her against him, and they rolled over on the grass, tangled together, still kissing. There were rocks digging into Clary’s back, and her shoulder ached where she’d fallen from the window, but she didn’t care. All that existed was Jace; all she felt, hoped, breathed, wanted, and saw was Jace. Nothing else mattered.

City of Glass, chapter 9; The Guilty Blood

And then You-Greg Laswell

"How my dreams they spin me 'round/And how my dreams they let me down/And how my thoughts they spin me 'round/And how my thoughts they let me down/And then there's you/Then there's you"

scene:

City of Glass, Epilogue; Across the Sky in Stars

Alibis-Mariana Trench

The moment the door shut behind Clary, Jace slumped back against the wall, as if his legs had been cut out from under him. He looked gray with a mixture of horror, shock, and what looked almost like…relief, as if a catastrophe had been narrowly avoided.
“Jace,” Alec said, taking a step toward his friend. “Do you really think—”
Jace spoke in a low voice, cutting Alec off. “Get out,” he said. “Just get out, both of you.”
“So you can do what?” Isabelle demanded. “Wreck your life some more? What the hell was that about?”
Jace shook his head. “I sent her home. It was the best thing for her.”
“You did a hell of a lot more than send her home. You destroyed her. Did you see her face?”
“It was worth it,” said Jace. “You wouldn’t understand.”
“For her, maybe,” Isabelle said. “I hope it winds up worth it for you.”
Jace turned his face away. “Just…leave me alone, Isabelle. Please.”
Isabelle cast a startled look toward her brother. Jace never said please. Alec put a hand on her shoulder. “Never mind, Jace,” he said, as kindly as he could. “I’m sure she’ll be fine.”
Jace raised his head and looked at Alec without actually looking at him—he seemed to be staring off at nothing. “No, she won’t,” he said.

City of Glass, chapter 6; Bad Blood

Day Old Hate-City of Color

At the table sat Jace. He was leaning forward on his elbows, his golden hair tousled, his shirt slightly open at the neck. She could see the thick banding of black Marks tracing his collarbone. He held a cookie in his bandaged hand. So Sebastian was right; he had hurt himself. Not that she cared. “Good,” he said, “you’re back. I was beginning to think you’d fallen into a canal.”
Clary just stared at him, wordless. She wondered if he could read the anger in her eyes. He leaned back in the chair, throwing one arm casually over the back of it. If it hadn’t been for the rapid pulse at the base of his throat, she might almost have believed his air of unconcern.

City of Glass, chapter 8; One of the Living

Never be the Same- Red

" I'm caught inside the memories, the promises, our yesterdays, and I belong to you/I just can't walk away/cause after loving you I can never be the same”

Scene:

“I don’t want anyone but you. I don’t even want to want anyone but you.”

City of Glass, chapter 9; The Guilty Blood

Go Away-Eisley

And leave me on my own/I am holding you (I am holding you)/I am holding you (I am holding you)"

Scene;

But Jace didn’t seem to see him; he was looking at Clary, and his eyes were hard as glass. Finally he spoke. “You’re right,” he said in a choked voice, as if he had to force out the words. “You should never have come. I know I told you it’s because it isn’t safe for you here, but that wasn’t true. The truth is that I don’t want you here because you’re rash and thoughtless and you’ll mess everything up. It’s just how you are. You’re not careful, Clary.”
“Mess…everything…up?” Clary couldn’t get enough air into her lungs for anything but a whisper.
“Oh, Jace,” Isabelle said sadly, as if he were the one who was hurt. He didn’t look at her. His gaze was fixed on Clary.
“You always just race ahead without thinking,” he said. “You know that, Clary. We’d never have ended up in the Dumort if it wasn’t for you.”
“And Simon would be dead! Doesn’t that count for anything? Maybe it was rash, but—”
His voice rose. “Maybe?”
“But it’s not like every decision I’ve made was a bad one! You said, after what I did on the boat, you said I’d saved everyone’s life—”
All the remaining color in Jace’s face went. He said, with a sudden and astounding viciousness, “Shut up, Clary, SHUT UP—”
“On the boat?” Alec’s gaze danced between them, bewildered. “What about what happened on the boat? Jace—”
“I just told you that to keep you from whining!” Jace shouted, ignoring Alec, ignoring everything but Clary. She could feel the force of his sudden anger like a wave threatening to knock her off her feet. “You’re a disaster for us, Clary! You’re a mundane, you’ll always be one, you’ll never be a Shadowhunter. You don’t know how to think like we do, think about what’s best for everyone—all you ever think about is yourself! But there’s a war on now, or there will be, and I don’t have the time or the inclination to follow around after you, trying to make sure you don’t get one of us killed!”
She just stared at him. She couldn’t think of a thing to say; he’d never spoken to her like this. She’d never even imagined him speaking to her like this. However angry she’d managed to make him in the past, he’d never spoken to her as if he hated her before.
“Go home, Clary,” he said. He sounded very tired, as if the effort of telling her how he really felt had drained him. “Go home.”

City of Glass, chapter 6; Bad Blood

As Much As I Ever Could-City and Color

“Love of mine, won't you lay by my side and rest your weary eyes/ Before we're out of time give me one last kiss/For soon, such distance will stretch between our lips”

Scene:

City of Glass chapter 14; In the Dark Forest

A Quiet Mind-Blue October

“I’m in pain but I won’t let you bandage my wound”

Scene:

Jace knew he was being cruel, and he barely cared. Hurting people he loved was almost as good as hurting himself when he was in this kind of mood.

City of Glass, chapter 6; Bad Blood

Maps –Falling Up

“The further I’m from you, the harder I try to exist/ Can somebody tell me how did it come to this?”

Scene:

“You know, there are some kinds of wounds you can get when you’re a Shadowhunter—internal injuries from demon poison. 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.”

City of Glass, chapter 9; The Guilty Blood

The King of Hearts-Alex Cornish

Not Allowed-Copeland

Scene;

“You came away from that thinking I was just fine?” Jace choked on something almost like a laugh. “I must be a better actor than I thought.”

City of Glass, chapter 8; One of the Living

Lightning Strikes-Angel Taylor

“Even when you smile the lightning lasts for seven miles/ And when you make me laugh I know this lighning will last”

Scene;

Clary, since the first time I saw you, I have belonged to you completely. I still do. If you want me.”
For a split second longer she stood motionless. Then, somehow, she had caught at the front of his shirt and pulled him toward her. His arms went around her, lifting her almost out of her sandals, and then he was kissing her—or she was kissing him, she wasn’t sure, and it didn’t matter. The feel of his mouth on hers was electric; her hands gripped his arms, pulling him hard against her. The feel of his heart pounding through his shirt made her dizzy with joy. No one else’s heart beat like Jace’s did, or ever could.
He let her go at last and she gasped—she’d forgotten to breathe. He cupped her face between his hands, tracing the curve of her cheekbones with his fingers. The light was back in his eyes, as bright as it had been by the lake, but now there was a wicked sparkle to it. “There,” he said. “That wasn’t so bad, was it, even though it wasn’t forbidden?”
“I’ve had worse,” she said, with a shaky laugh.
“You know,” he said, bending to brush his mouth across hers, “if it’s the lack of forbidden you’re worried about, you could still forbid me to do things.”
“What kinds of things?”
She felt him smile against her mouth. “Things like this.”
