One

Clary had always had a knack for seeing through glamours, which was why she wasn't surprised when she spotted the three, prowling figures before her brother did. She held out a hand, stopping him in his tracks, "Jonathan look!"

He sighed, long since resigned to his sister's demands, "Where am I looking?"

"Directly across the street."

His green eyes narrowed in concentration, mentally peeling away the layers of magic to reveal what Clary had already seen; three black-clad teenagers stalking purposefully down the busy street, invisible to the mundanes around them.

"They're shadowhunters!" she exclaimed excitedly.

He rolled his eyes, "I can see that thank-you. What I don't see is why that matters to us."

She poked her tongue at him, "It matters because they're probably one their way to do something awesome, we should follow them."

He was already shaking his head, "No. No way."

"Come on, it's my birthday!"

"Turing sixteen doesn't automatically save you from mom's wrath."

"You worry too much. Please, can you just this once do something childish and stupid?" Clary made her eyes go as big and pleading as she could, he caved.

"If we don't hurry up we're going to loose them."

She clapped her hands in delight, "Yes!"

Jonathan sighed, "I know I'm going to regret this."

Clary shot him a devilish look over her shoulder, already moving after her newfound quarry. "Almost definitely."

Clary and Jonathan had been following the teenagers for the past ten minutes and so far they had done nothing of any real interest. They were over a hundred metres in front, any closer and they would have realised they were being followed. Even from this distance the only reason they hadn't spotted the duo tailing them was the overcrowded nature of the street and their faith in their glamours. Jonathan seemed to be thinking the same thing, "They're relying on their glamours too much, if they were paying attention they would have noticed us."

"They probably think they're the only shadowhunters in New York and who else is going to notice them when they're glamoured?" Clary reasoned.

"Any demon who bothers to look is going to notice and then they'll be in trouble."

"I don't know, it kind of seems like trouble is exactly what they're looking for." Clary went back to studying the figures ahead of them, there were two boys and one girl, all around the same age as her and Jonathan. The girl and one of the boys looked alike enough to be siblings, with their dark hair that contrasted perfectly against their pale skin. Even from behind Clary could tell they were gorgeous, both blessed with tall, lean bodies and graceful movements. But it was the second boy who caught and held Clary's attention.

He was like a Greek myth; a victim of Midas's golden touch, blonde hair and sun-kissed skin. And then he glanced behind him, his gaze travelling over the street and coming to rest on Clary. She did her best to emulate the expressions of the mundanes around her, as though she was looking through him as opposed to at him. He studied her and her heart quickened, it wasn't just his skin and hair that was gold, so were his eyes. Shadowhunters were made using the blood of an angel but this boy looked like one, too beautiful and remote to be human. He made her itch for her art supplies, this boy needed to be drawn.

He turned back to confer with his companions and Clary let go the breath she hadn't realised she was holding. Jonathan grabbed her arm "Did he see you?"

"He saw me, but I don't think he realised I could see him too." Jonathan sighed in relief, he may not have been thrilled by the idea at first but he had committed to this game, being spotted meant you had lost and defeat was not a concept Jonathan was comfortable with.

"I wish I had Heosphoros." Clary grumbled. She'd had the sword since she was old enough to carry it without impaling herself and she hated going anywhere without it. Jonathan shot her a side-long smile, "I'm first to admit that mundies are notoriously unobservant, but even they will notice a small girl with a large sword walking down the street." Clary elbowed him in the side for his comment on her height but had to admit he had a point. Besides, it wasn't a though she was unarmed, she had a seraph blade concealed in her jacket and a runed dagger in its special sheath in her combat boots. She also had a few important runes, inked onto her skin and hidden from the mundanes by her clothes. Jonathan had some too but nowhere near as many as the trio they were following, because of their glamours they had no need to hide them, they swirled across their skin, blackened lines burned onto their bodies in numbers so great their skin was nearly entirely covered. Runes for speed, strength, agility and of course glamours, Clary had never seen so many runes on a person in her whole life. Where ever they were headed they were clearly planning for a fight, a big one.

As they walked the foot traffic got thinner as they headed into a more industrial area. Scary looking dilapidated warehouses rose up on all sides and Clary and Jonathan were forced to stay even further back to avoid being spotted. Then the trio came to a particularly intimidating looking warehouse and after a quick discussion slipped inside. Clary burned with curiosity and wanted nothing more than to follow but Jonathan held her back, "Mom is going to go utterly ballistic if we die on your birthday, we're supposed to be home by 5 O'clock if we're not there on time she'll probably send out a search party." It was true, Jocelyn Fairchild had an overprotective streak that made grizzly bears look tame.

"Come on Jonathan!" she knew she was whining but she couldn't help it, she desperately wanted to see where they were going, "It's not five yet and we've come all this way. Where's your sense of adventure?"

He raised one eyebrow and Clary seethed with jealousy, she been trying her entire life and she still couldn't pull off that expression. "I suspect it's in the same place as your sense of self-preservation." He quipped, but he let go of her arm and began moving toward the door that the others had slipped through so she knew she'd won the argument. He cracked it open and peeked inside, "Just don't do anything stupid." He said with the weary acceptance of a flight attendant giving safety directions they know on one is listening to. Then he led the way into the dark warehouse.

So this is my second attempt at FanFiction, my first kind of crashed and burned, well not really, crashing and burning implies some epic failure. It more withered and died.

I've created a kind of parallel universe in this multi-chapter, a few changes in the very beginning of Clary and Jonathan's story which had big ripple effects in the lives all around them. The biggest difference? Valentine feed Jonathan Angel blood instead of demon. The rest will be revealed through-out the story.

PLEASE, PLEASE, PLEASE REVIEW! It would make me so happy!
