My first fanfic! I hope you enjoy! And of course all the original ideas and characters go to the wonderful Miss Clare.

Chapter 1

Ah, demon hunting once again. I still get a high from it. Just being able to slice the scourge of the earth to pieces excites me. And making them feel the pain they have brought from their dimension is what they deserve.

Alec, Izzy, and I were in Pandemonium, tracking down another bastard from hell.

The club was packed, as usual. Colored strobe lights and smoke roiled around the room. The dance floor was at max capacity with too many grinding bodies to count. Guys in dark jeans and leather jackets slid their hands up and over random half naked girls on the dance floor, pulling each other closer every second.

And to be honest, I felt a little left out.

Alec leaned over and whispered in my ear, "See the psycho drooling over Izzy?" I nodded. "There's our target."

I tapped Izzy's shoulder. She smiled, transforming into a sly predator. The demon couldn't resist, following her straight into the storage closet that read 'NO ADMITTANCE'.

Alec glanced at me as we both drew out our weapons. I quickly pushed the door open, not that I was afraid for Izzy, I knew she could handle it, but I wanted to begin the hunt.

When we opened the door, the demon was on the ground, tangled in Isabelle's golden whip. She laughed, tightening the rope. "He's all yours, boys." I smiled and grabbed it by the shoulders, smashing it against a concrete pillar.

"So are there any more with you?" I questioned, meeting its acid green eyes. I grimaced; they were sickening.

The blue dye must have already gotten through its rotten head, because it stupidly said, "Any other what?"

I smirked. "Come on now." I raised my arms, exposing the fresh runes. "You know what I am."

It hissed, glaring. "Shadowhunter."

Alec grinned, catching onto the game. "Got you."

I grinned like a lunatic as Izzy pulled tighter on the bond, cutting deeper into its wrists.

I folded my arms across my chest, pacing back and forth in front of our captive. "So", I began. "You still haven't told me if there are any other of your kind with you."

The demon scowled, "I don't know what you're talking about." I sighed, so it's going to play stupid then.

Alec cut in, sounding very exasperated, "He means other demons. You do know what a demon is, don't you?"

I slowly paced back and forth, "Demons are religiously defined as hell's denizens, the servants of Satan, but understood here, for the purposes of the Clave, to be any malevolent spirit whose origin is outside our own home dimension—"

Izzy sighed, "That's enough, Jace."

"Isabelle's right," agreed Alec, "Nobody here needs a lesson in semantics—or demonology."

I smirked, leaning toward the demon's sweat drenched face. "Isabelle and Alec think I talk too much. Do you think I talk too much?"

It turned its pale face away, momentarily silent. "I could give you information, I know where Valentine is."

I didn't believe it; I turned to Alec. "Valentine's in the ground, the thing's just toying with us."

Isabelle whipped her hair back. "Kill it, Jace, it's not going to tell us anything."

I raised my left hand, exposing the translucent blade of Sansanvi.

The demon gasped, trying to escape, only to have Isabelle pull tighter on its wrists. "Valentine is back! All the Infernal Worlds know it—I know it—I can tell you where he is—"

The blood boiled beneath my skin and I resisted the urge to crush its throat. "By the Angel, every time we capture one of you bastards, you claim you know where Valentine is." I took a breath. "Well, we know where he is too. He's in hell. And you," I spun the knife around to face its throat, "you can join him there."

"Stop!" A voice screamed, "You can't do this."

I was so taken aback that the knife slipped from my grasp, skidding on the floor. I looked at up at a short fiery haired mundie girl. I almost scoffed at what she was wearing. It was the most outcast apparel for a club: T-shirt, jeans, and bright green sneakers.

But as I drew my gaze upward and settled on her face, I noticed she was very pretty. Red hair fell around her shoulders in soft curls. And underneath the fiery flames was a soft pale face holding large emerald eyes that were staring straight at me.

Alec turned to look at the mundie then me. "What's this?"

I smirked, covering myself with a sarcasm. "It's a girl, surely you've seen girls before, Alec. Your sister, Isabelle is one."

I came closer to the girl. And the closer I got, the prettier she became. Her alarming height reminded me of a vicious sprite. Though she was really quite stunning; thick lashes framed her lively evergreen eyes, so clear that it felt as if she could see through me. A light layer of pale freckles dusted the top of her nose and stretched out along her cheekbones. The delicate angle of her cupid's bow were like small arrows, begging me to look. Her pink lips were turned down at the corners in an angry pout and I had the strangest urge to make her smile.

An image of me touching those lips flashed across my mind. What was wrong with me? She was just a mundie girl...

"A mundie girl," I half whispered. "And she can see us."

The girl frowned and pouted her lips again in that appealing way. "Of course I can see you, I'm not blind you know."

I smirked, thinking of how naïve she sounded. "Oh, but you are," I said as I retrieved my fallen knife. "You just don't know it." I stood up and met her gaze. "You'd better get out of here, if you know what's good for you."

And for some strange reason, I knew what she was going to say next.

"I'm not going anywhere, if I do you'll kill him." She pointed toward the demon.

"That's true," I said turning the knife in my hands. "What do you care if I kill him or not?"

The girl stuttered. "Be-because—, you can't just go around killing people."

So that's it, she was trying to be a hero, saving the lives of "innocent" citizens.

"You're right, you can't go around killing people." I pointed to the demon on the pillar. "That's not a person, little girl." I internally smirked, that just had to bother her. "It may look like a person and talk like a person and maybe even bleed like a person, but it's a monster."

Isabelle warned, "Jace, that's enough."

She backed up, fright coloring her voice. "You're crazy, I've called the police, you know. They'll be here any second."

"She's lying." Alec said, but he sounded doubtful. "Jace, do you—"

Alec was interrupted by a high-pitched scream. I whirled around, but was too late.

The demon had broken free and slammed into my shoulder, knocking me to the ground. I raised my arm to protect my priceless face as it slashed wildly with razor sharp claws, drawing blood from my arm.

Alec and Isabelle ran to my aid, even though I could take perfect care of myself. Izzy whipped its back as it came at me again, making the demon screech.

Rolling over, I picked up my blade, stabbing into the demon's chest. Black blood dripped beneath the hilt of the knife. I frowned; my shirt was now darker than before with the black liquid. I leaned down to rip the blade from the demon's chest.

It convulsed and glared at me. "So be it. The Forsaken will take you all."

I growled in response as its body disappeared.

Alec rushed to my side, immediately checking to see if I was hurt. Always looking out for others.

I heard a gasp of pain and turned to see Isabelle holding the girl in the grasp of her golden whip. I had completely forgotten she was here, that she could see us.

She scowled, tugging at Izzy's snare. Like a kitten stuck in the claws of a tigress.

Isabelle hissed, "Stupid little mundie, you could have gotten Jace killed."

The girl pulled again, looking at me accusingly. "He's crazy, you're all crazy. What do you think you are, vigilante killers? The police—"

Holding my arm, I stepped over the wires and cables to her, Alec close behind me. "The police aren't usually interested unless you can produce a body."

She bit down on the side of her lip, making it red. Her cheeks were tinged pink and long lashes shadowed her wide green eyes. Once again her beauty struck me.

She looked past me to the place on the floor where the demon was moments ago.

"They return to their home dimensions when they die," I said, the words tumbling off of my tongue. "In case you were wondering."

"Jace," Alec warned. "Be careful."

I furrowed my brow, confused again. "She can see us, Alec, she already knows too much."

Izzy frowned and glanced at her nails. "So what do you want me to do with her?"

"Let her go." Izzy looked at me as if I was insane, but didn't argue.

The girl rubbed her wrist, slowly backing away.

"Maybe we should bring her back with us," said Alec. Hearing that I felt a flourish of hope and excitement, but I buried such frivolous thoughts. "I bet Hodge would like to talk to her."

Isabelle sharply snapped back. "No way are we bringing her to the Institute, she's a mundie."

"Or is she?" I quietly questioned, looking at her more closely. "Have you had dealings with demons, little girl? Walked with warlocks, talked with the Night Children?" Maybe that would explain this hold she had over me. "Have you—"

She cut me off. "My name is not 'little girl' and I have no idea what you're talking about." Really? "I don't believe in—in demons, or whatever you—"

"Clary?" The name came from nowhere.

So that was this girl's name. Pretty, it fit her well.

A tall, mis proportioned mundie stood in the doorway with an annoyed looking bouncer at his side. He squinted at Clary in the dark, looking for something. Good, he couldn't see us.

"Are you okay?" His voice was soft, too soft. "Why are you in here by yourself? What happened to the guys—you know, the ones with the knives?"

Clary turned, confused as to why they couldn't see us. I smirked and shrugged in reply.

She turned back around, and I almost felt sorry for her.

Her excuse nearly made me laugh. "I thought they went in here… But I guess they didn't, I'm sorry."

The kid's face grew red and he turned to the bouncer, not looking him in the eyes, "It was a mistake."

The bouncer grunted and muttered, "Stupid kids."

Izzy giggled as she climbed through the window and onto the street. With one last look at the girlI leaped through the window.

~oOo~

Once we were on the street, Alec and Izzy began arguing.

"She must be a downworlder."

"No downworlder would be so shocked at us killing a demon. Besides, there were no obvious signs."

I winked at her, "Not that we could see."

She glared at the sky.

"Izzy, we should tell Hodge-"

Clary, Clary, I liked the way her name rolled in my mind. I wished I could say it out loud…

"What did you think of Clary?"

Alec sputtered mid sentence. Izzy raised a dark brow, but they continued to walk.

I stopped, waiting for an answer.

Izzy planted her foot on the ground and placed her hands on each hip. "Should I care?"

Alec turned back midstep. I looked at him expectantly. "Why?" He stared at me dumbfounded.

"Clary's a mundane who can see us, isn't that fascinating?" I could feel the amused gleam in my eye.

She crossed her arms, "No."

Alec ran a hand through his hair, "Why did you let her go? She's a threat now Jace."

I scoffed. "Clary? A threat?"

He grimaced, "She may not look like much, but she could still cause trouble. Mundie or not." He glanced at Izzy.

I shook my head and began walking.

"Jace!" Alec easily matched his strides to mine.

"How is she a threat?"

Izzy pulled up to the other side so I was now caught in between them.

He began with a reasoning tone. "She can't be trusted Jace." I rolled my eyes. He hissed, "We don't know what she is."

I genuinely laughed. "If she's a mundie she will be locked up and if she's a downworlder, who cares, just enforcing the law."

Izzy sighed dramatically. "Leave it alone. She's a burden we don't need."

"Hodge deserves to know! There hasn't been a mundie who's had the sight for a thousand years."

I snickered, "She's a mundie now?"

His eyes narrowed. "I don't know anymore than you, that's why we should have brought her to Hodge."

I smirked, knowing it would anger him. "Are you implying we should have kidnapped her?"

He frowned. "I'll tell Hodge. I'll tell him you let her go without questioning-"

"I questioned and she didnt know-"

Alec continued, "Without proper questioning."

"Both of you, shut up." Izzy yawned, "Hodge will hear you out here." She began climbing the front steps.

The institute loomed before us. Both inviting and forboding.

I shrugged, my resolve spent, he would tell either way. "Why would I care what you tell Hodge about the mundie?"

"Jace-"

I turned and started up the grand stairs.

~oOo~

I settled uneasily on my bed.

How could this girl drive me, Jace Lightwood, nearly insane with curiosity? She couldn't be human. I do admit that I have fallen under the influence of a few attractive downworlders before. But never to this extent... There weren't any obvious signs of dark heritage though, other than her being not much taller than a sprite. I smirked, she was so fierce and innocent. Her bright green eyes widened with fear and her nose wrinkled in disgust as I extracted the blade from the demon.

I smirked, the memory of her was a fresh wound in my mind, I wasn't forgetting her scar anytime soon.

Well there is the first chapter. Thanks for reading. Reviews will be greatly appreciated!
