It is an OCxJace pairing but I am not bashing Clary. I love JacexClary but~ it kinda disappoints me of the lack of OCs but I wouldn't blame anyone because all the characters are so wonderfully created.

SUMMARY: post CoFA- New problems arise after the death of Lilith. A new Shadowhunter has entered New York and she's not in the records. The Clave has suddenly gotten quiet, Downworlders are starting a war with each other. There has been rumors but if any of them have been true, the Shadowhunters would have every right to fear. originally Black and Silver Secrets *hiatus*

DISCLAIMER: I do not own the Mortal Instruments series. And so happy I do not in a way because if so, then it would not be as amazing. But Alyssia Jackie Stroughn is mine.

Now on with the story

Chapter 1

A teenage girl tightly grasped her stele in her hand. Sweat beaded down her forehead and mixed in with the blood and debris that covered her face. She was weapon-less as the behemoth demon that was following her made it useless. A few blocks away she could see her goal, a church, hopefully one that wasn't raided for all the weapons. She looked over her shoulder to see her predator wasn't there till she heard a low buzzing noise in front of her. She snapped her head forward, her black hair whipped around her, and saw the demon right in her path.

"Ugh damn it!" She skidded out of the way to hit a stop sign and caused it to dangerously lean to its side. She glared at the demon before completely kicking over the stop sign fully displacing it from the ground. The Shadowhunter had a new weapon: a beaten metal stake. She had her eyes off the behemoth for a second and then next thing she new it vanished. There was no signs of evidence to show that it was ever there.

The Shadowhunter growled in disbelief at the waste of energy and vandalism. She threw down her pathetic excuse of a weapon and limped her way down to the church clutching her arm in pain.

Jace opened his eyes and groggily looked through his long lashes. He sat up on his bed and swatted his blonde locks off of his face.

'It's been a while since I dreamt of something like that...' The angelic looking boy dazed as he grabbed some clothes and headed towards the shower. His mind wandered to the night he first dreamed of Clary a couple of months ago. His brow furrowed as a realization dawned upon him. Last night was the first time he didn't dream of his fiery, red-headed, emerald eyed princess.

His thoughts and emotions muddled as he showered. The warm water trickled down his body and traced his scars. His arms and torso were decorated with the silvery glint of runes. He looked down at himself and eyed the Mark of Lilith. He sneered in disgust as he recollected memories of what happened earlier. When he was possessed by Lilith and nearly killed Clary, and how a part of him felt at ease doing so. Jace slammed his fist into the shower walls before turning the water off and dried himself off.

'Well good morning yourself little-brother'

Jace reflexively snapped his head up and looked around during the process of slipping on his pants. Even though he knew of the newly formed connection he and Jonathan shared, he couldn't help but act on what he instinctively knew.

'What do you want?' Jace mentally spat.

'Is it a crime for me to greet my brother in the morning?'

Jace groaned knowing that he wasn't going to win this mental challenge so he proceeded with his normal routine and threw his clothes in the hamper.

'What was your dream about?'

'You're being quite nosy. But I know, I'm just that charming.'

'Your charismatic antics won't work on me.'

'Denial is not just a river in Egypt.' Jace ended his conversation with Jonathan and proceeded to the kitchen hoping that Isabelle wasn't cooking breakfast. Unfortunately, his extra dosage of angelic blood did not give him any extra good luck. He entered the kitchen seeing the counter cluttered with broken egg shells, spilled milk, drops of batter and a cluster of plates. Isabelle was at the stove, hair tied up and wearing an apron as she poked at whatever poisonous concoction was in the frying pan.

"Isabelle... what in Angel's name are you doing?" Jace eyed the pan afraid to see what disaster was brewing. His fellow parabatai came in and held the same disgusted face as he saw Isabelle cooking.

"Isabelle... I think I'm going to go on ahead to see Magnus and head out." Alec stuttered on spot before dashing through the door and left Jace to be the victim.

"I know my cooking is disastrous but maybe it's the lack of support from my brothers." Isabelle scrimmaged and made a face at Jace. She turned back to the pan to see the blob of batter move and not because it was of the heat. She instantly let out a yelp and dropped the spatula. She turned off the stove and threw her apron on the ground and grabbed Jace's wrist. "You know maybe Alec is right. Let's go over to Clary's and beg for food."

That feeling Jace was expecting didn't come. It wasn't the happy warming butterfly feeling he used to get when he heard her name. Now it was more of a calm acknowledgement.

'Someone having girl troubles?'

"Shut up..." Jace growled out loud causing Isabelle to stare at him with a worried expression. "Sorry didn't mean to say that out loud... Wait that came out wrong." He tried to correct himself when he noticed his sister's confused expression. She was probably wondering if just the mention of Clary's name was taboo after the incident that happened.

"Don't worry about it." Her voice sounded far off in the distance.

They were only a few blocks away from Luke's house when Jace's sensor buzzed faintly. He stopped Isabelle and reached in his pocket. It showed signs of faint detections of demon presence.

"Isabelle. Something happened here." Jace's golden orbs eyed at a fallen stop sign on the street. It was clear that it was purposely knocked off it's usual upright position. Dirt was dug up from the curb and traces of dried blood was present in the area. Isabelle scooped the area but kept taking occasional glances at Jace.
"Jace... is there something going on?" Isabelle rested her hand on Jace's shoulder only to be rewarded with a cold glare and Jace motioned out of her reach.

"Come on, there's a church a ways off. Also there's a slight trail of blood leading towards it apparently." Jace replied in a cold tone and headed towards the church. All Isabelle could do was watch her adoptive brother walk a ways ahead of her with a solemn look in her eyes.

As he walked onward, he regretted how he treated Isabelle but he couldn't bring himself to say it. He kept thinking about what Madame Dorothea predicted for him from his tea leaves '… You will fall in love with the wrong person.' He felt sick to his stomach. Was the wrong person Clary? Just because they both have Ithuriel's blood run in their veins, and so does Simon now, does that mean they were all related? Is he in love with his angelic-blood related sister? Or is it some kind of sick joke? Or is the wrong person the girl he dreamed of? He stopped abruptly and shook his head. 'No. Don't think that. You don't know the girl much less know her name. You can't be in love with someone you don't know. And besides this must be some sort of coincidence... who am I kidding.'

'You don't know little brother. Destiny has an interesting way of connecting two people together with the String of Fate.'

'Shut up and leave me alone in peace.' With that Jonathan left Jace's confused mind to himself.

He grabbed a seraph blade in his hand as he neared the church, Isabelle caught up to him and her whip around her wrist and easily open to use when necessary. Even though he was physically prepared for anything that could happen, his mind was some place else leaving his sanity vulnerable. Isabelle seemed to notice and gave him a slight slap to the shoulder. Jace's clouded eyes started to clear and he gave a nod signaling that he was alright. They hastened up the church steps and noticed blood on the doors, as if someone was leaning there.

"In the name of the Clave I ask entrance to this Holy Place..." The doors swiftly swung open before Isabelle could finish the oath.

"Looks like the great Angel Raziel knows our purpose. Come on." Jace walked in ahead of Isabelle. His voice and demeanor gave off the impression of apathy but his mind was reeling with questions and his heart was fluttering faster than a hummingbird's wings. His dream replayed over and over in his mind. An average height teenage girl who was a Shadowhunter no doubt. Her hand was clenched around a stele and her black hair was tied up in a high ponytail but there were loose strands from endless running and defending herself. Her silver eyes brought luminance and contrast to her sun-kissed skin even though she was covered in a sheet of dried blood and grim. She had on the traditional black gear and showed signs of usage. Jace lightly blushed as he continued to drool about a fictional girl in his dreams, but then again, he first thought Clary was a fictional character that his mind made up and look how true that was.

He shook his head clear of those thoughts and proceeded to scan the inside of the building. He held out his witchlight to illuminate the dreary scene and noticed the blood trail continue up to where the altar was. Isabelle waved Jace over to a trapdoor where there should have been a storage of seraph weapons should be hidden.

"Looks like someone stocked up." Isabelle grabbed a forgotten blade and felt the slime trickle down her hand and wrist. "Ew! Gross! Behemoth mucus!" She dropped the blade on the stone tiled ground which did not go quietly. She rubbed her hand clean on her shirt and felt her whip lose contact with her wrist. "Jace-"

"Someone's still here." His eyes narrowed to slits and looked back and forth scouring for the thief. He suddenly felt his left arm with his blade get caught behind his back and a glowing blade graze his neck and dropped his witchlight.

"What are you doing here?" A melodic feminine voice cut through the air easily as if it were butter.

"Who are you?" Isabelle stood her ground in front of the captor and the captive.

"You're one to talk without any other weapons and my name doesn't matter." The unknown girl said.

"Look I know that I'm quite the catch but I preferably be the one who does the chasing and I too would like to know the name of the impressive dame who was able to sneak up on me." Jace commented nonchalantly.

"Be quiet pretty-boy-"

"Well I'm glad that you noticed that or else it seems that the world has come to an end." Jace tried to turn his head and give his signature smirk but was pushed forward into Isabelle. The two were caught off guard but quickly built their composure again when their weapons where tossed back to them.

"Just get out of here. Go back to wherever you were doing before hand." The teenager turned around towards the door and began to run. Jace quickly dashed after her catching her with ease and held her close to him.

"I told you I prefer being the predator." Jace huskily whispered in his prey's ear.

"And I prefer that you let go of me this instant." She growled and struggled to break free of his grasp.

"Well I must say, you do make this interesting, Usually girls would love to be in your position right now." Jace flaunted his tone. 'It's her... it's actually her... that girl in my dream last night...'

Isabelle's boots clanked against the paved floor of the church as she walked over to the girl in Jace's grasp. She brought her hand to the Shadowhunter's chin and forced her head up. Isabelle jumped back with a gasp. Her face full of astonishment and terror. Tears were brimming in her eyes and threatened to fall.

"Alyssia!"

So that's chapter one. What do you think? Comments/questions/critiques/criticism are all open in the review section. Simon and Clary will come into the story soon enough just had to get Alyssia in there somehow. Sorry if the characters are OoC I am trying to fix that and the same time, trying to fix my writing style. That's really my main goal in this fan-fiction is to improve my writing.

So that's really all right now. I'm really hoping that I can get through this fan-fiction all the way through because~ I actually developed a plot to follow! Yay!

Oh and I won't mind having a beta-reader as well!

Okay till next chapter!
