Chapter One

The Mission

"Hey Clary!" the boy in the blue hoody yelled from across the busy street, as he ran across the road. Stopping a yellow cab as it honked loudly at him. The woman laughed as she shook her red curls out of her face. The boy drew closer and she could clearly see his brown eyes and chocolate hair covering his forehead.

"Hey Simon," Clary said whilst he began to walk in step beside her "What are you doing on this side of town?"

"I could ask you the same question Fray," Simon replied, looking down on her small frame

"I'm off to visit the Institute," She told him in a matter of fact tone.

"Well what a coincidence so am I," he feigned surprised "and what might bring you to church on such a delightful day as today?" he asked whilst holding both arms in the air pointing towards the grey, cloud filled sky. She rolled her eyes at her best friend and let out a short laugh.

"I don't know Simon…" Clary paused for a few seconds pretending to be deep in thought "why are you going to church?"

"Hmmm… well seeing as its Sunday I decided it would be a good time to start going to church and find my inner connection with god." He joked

"Of course" Clary laughed and nudged him in the ribs "more like your inner connection with a certain Lightwood girl"

"Hey that's not true Alec's not a girl!" Simon chuckled as he denied the accusation "And he is with Magnus remember" he added as an afterthought. Clary smiled at his lame joke and Simon threw his arms over her shoulders to hug her neck closer to him.

"I don't think I was talking about Alec" Clary replied with a knowing look.

"I have no idea what you're talking about" He said giving her an innocent look.

"Sure, sure…" clary replied as they began to climb up the warn out steps to the old church. Simon pretended to give her a hurt look as they opened the huge oak doors and stepped into the cool building and walked down the centre aisle of the church pews.

As they both walked towards the elevator a loud alarm began to eco throughout the church and Clary quickly rummaged through her messenger bag hanging on her shoulder until she fished out a silver device. She held it to her ear and the noise was cut off.

"Hey Jace" Clary said with a smile on her face. Simon heard some mumbling from the phone, presumably Jace. Then he watched as her smile faded and her eye brows knitted together in confusion. "Uh Hu…" clary mumbled then was quiet. Simon guessed listening to Jace speak on the other side "okay we're already on our way, see you in a few." She said then hung up.

Simon looked at her with a puzzled expression. Then she shrugged and said "Maryse has called everyone to a meeting in the library to discuss something with us." Jace obviously hadn't told her much more because she looked almost as confused as Simon.

So they approached the elevator and began to ascend into the institute.

When Clary and Simon reached the library they could hear loud yelling from behind the doors. Clary put her hand on the doorknob then turned to give Simon an uneasy look. He returned it and she opened the old doors to see three teenagers sitting on the red lounge together, all looking towards the woman behind the old oak desk.

Clary watched the scene in front of her. Washing her eyes across the people in the room. One with long ink black hair cascading down her back looking outraged. The boy next to her looked slightly older and had short hair but it was the same ink black as the girls, looked as usual relaxed yet uneasy. Then Clary's eyes stopped on the gold hair and amber eyes, although this time they were filled with disbelief.

Then his eyes met Clary's and brightened. As the other three people turned around and the room became quiet.

"Ah Clary, Simon nice of you to join us so quickly," The woman with the grey streaked hair said from behind the Large table.

"Umm... thank you Maryse" Clary replied after a moment's hesitation. Then she took a seat on the arm of the lounge chair next to Jace. Simon hot on her heels taking a seat on the other arm, next to Alec.

After a moment of silence Clary spoke up "well, aren't you going to tell us why we're here?"

Jace chuckled a humourless laugh, and Maryse glared at him.

"Yes, I am." She said sternly suddenly remembering why they were there. She sat up straight looking very serious, almost like a business man about to direct an important meeting Clary observed "We have been informed by the Clave that there is a rogue shadow hunter living in New York. Yet the Clave presume she does not know of her true identity." She paused, watching their reaction. Then began again when she was satisfied "She may be a threat or be threatened if you don't stop her. Therefore your next mission is to help her to understand what she is." Maryse finished with an uneasy look towards the teenagers.

Clary thought for a moment about what she had said then looked at the other four people sitting on the couch beside her. Then Simon turned to Maryse and asked "How do we plan on doing that?"

Maryse looked at him for a few seconds then replied "Well… your all going to be undercover at…" she paused for a moment, looking as though she would rather be anywhere else, Clary presumed due to the earlier reactions from the Lightwood children when Maryse had told them, before she and Simon had walked into the room. Maryse took a large gulp then finished "… school."

It took Clary a moment for it to sink in, and when it did she quickly turned her head to look at Simon with a smile on her face. He returned her gaze with a grin of his own.

The four Lightwoods watched Clary and Simon's reaction to the news. Yet they were surprised when unlike the three siblings, Clary and Simon looked excited. Jace watched Clary with utter fascination; he knew she had gone to high school when she was living as a mundane. But he didn't expect her to want to go back. Although he hadn't really given it much thought.

The room fell quiet once again. Everyone looked at each other awkwardly until Simon broke the silence "Um… So when do we begin?"

Maryse took the enthusiasm as a good sign and replied with more confidence than before "tomorrow"
