Okay so this my first story and I would appreciate all comments, as long as they tell me constructive stuff and not just calling me a bad writing or any thing similar. So this idea came from one of my dreams (I know, thats so weird) and i had to put it on paper or the internet...

So in this story, Jem and Tessa all ready married, Will is still single, Jem is not dead yet... and... there was something else that I can't remember but I will include in later chapters (if I make any other chapters... You guys are going to have to help me decide)

Disclaimer: I don't own any of these characters, aside from my OC's (Angelica). All rights and what not go to Cassandra Clare and Infernal Devices Trilogy...So yeah...

Chapter 1

Jem's POV

I sat at on a couch in the library of the London Institute. Standing front of me was Charlotte, Henry, Will, Tessa, Sophie, Cecily, Gabriel, and

Gideon. Most of the men had there arms crossed over their chest and a stern expression n their faces. The London Enclave had just given us an

important mission; a mission that I wished hadn't been accepted. Us, the shadowhunters of the London Institute, were going to find the

wretched demon that destroyed my life forever.

Charlotte had asked me to tell them about the night that Yanluo attacked and killed my family.

I had already explained to them already what happened that night, but they wanted more detail. What I had told them was only the extremely

simplified version of that night. If they wanted the detailed one, I have to tell them about her and what I did for her…

"Fine, if you want the detailed version I will tell you the detailed story. How ever, if you don't like what you here, it is your fault…" and I began.

"It was like any other night in Shanghai. We trained; we had company, nothing out of the ordinary. But my sister was attacking odd. When we

trained in the courtyard, she was constantly looking over to a part of the wall that surrounded the Institute. She warned my father that the

area was weak and the barrier that protected us was almost broken in that spot. But he wouldn't listen. He dragged her inside and told not to

say anything else that was foolish. He told her to go to her room until dinner.

She listened, like she always did. She went to her room and didn't come out until dinner. When she did, she was pale. Extremely pale. My

mother thought she was ill. But she wasn't. She told my mother that there was a demon coming to get her. To kill her. Father lost it. He hit her,

saying that she was acting foolish and no demon could get in to harm her. She was sent to bed without any supper. I was sent to bed shortly

after.

My room was right beside Angelica's, my sister, room. I was worried about her, so I went to go see if she was alright. She was not alright. She

collapsed on me and started shaking. Her eyes went pure black; black as a nightmare. Her skin went white like snow. She spoke, but it wasn't

her voice. The voice was deep and cut like a thousand knives. It said that it was coming to kill, to get revenge and it would start with her. Then

the voice was gone. Black lines started appearing on her skin, like veins. Her breathing became raspy and sounded liker she was choking. Her

voice was weak. Weak and quite, but it was Angelica's voice. She said to run, and leave the Institute. Then she screamed…"

I had to stop. I couldn't continue. It was too painful. Tessa had seated herself beside me and was holding my hand. Most expressions now were

pale and some, Charlotte, Cecily, Tessa, and Sophie, even had sickened looks.

"Oh, dear god Jem."

"And your sister too."

"And your were only twelve."

"How old was your sister?"

"Can you continue? We need to know the rest of the story." Gabriel said. I glared at him.

"Fine." I took a deep breath and continued. I told them about how Angelica had lost consciousness and how I ran to go warn my parents. "I told

them about what had happened to Angelica and what the voice had said. My mother started swearing in Mandarin Chinese. She started for

Angelica's room, but Yanluo stopped her. He had to be at least seven feet tall. He was humanoid, but his eyes were pure black and his skin was

the color of hurricane clouds. His teeth were fangs and his hands extended into claws. In his hand was Angelica. She was no longer

unconscious. Her black hair covered her face. Her dark eyes were wide with fear. I had never seen my sister like this. She was always the

stronger twin. Always the fighter, but she was terrified. Tears were streaming down her cheeks and she called out for mother. My father did not

move, just stared at the demon in shock. My mother screamed and cried out for her. The demon's free hand jerked out in front of him, and my

parents were bound to chairs. My mother was still screaming for Angelica. Yanlou bound Angelica to a chair. He turned to my mother and started

talking to my mother in the same voice that my sister had speak through her. He said that he was going to get revenge on her for her killing his

offspring by killing her child. Then he turned back to Angelica and touch a claw to her chest. She screamed. My father and my mother screamed

and called out for her. Yanlou didn't seem to notice me as I grabbed on of my father's hidden seraph blades. I whispered it's name, then

attacked Yanluo. I stabbed him from his left shoulder to his right hip. He howled and spun around. I was able to get to free Angelica and we

were able to get out of the great room.

Angelica was weak. She was breathing heavily as she sank to the ground. She didn't say anything, but she started crying. She clutched a hand

to her chest, the spot where Yanluo had touched her. She looked up at me and whispered something quickly; her face was full of fear. I didn't

hear what she said, but I wish I did. Then I lost consciousness.

"I woke up to find myself bound to a chair, facing my parents. Yanluo stood off to the side, holding a knife to my twin's throat. He told me that

he would kill Angelica or he would kill me. He said he didn't care which. I told him he could take me, and leave my sister alone. He leaped at me,

releasing Angelica. Suddenly I was filled with a burn pain, worse than anything I had ever imagined. My mind screamed as I watched

hallucinations pass before my eyes. It was like this for two days. Sometimes I would enter reality long enough to hear my parents screaming for

me. Then I would slip away into the horror. One day I came back, only to hear my mother's voice. My father's had been silenced. I could not

hear Angelica. Then I was injected with demon substance again. It was on the last day did I hear nothing, not mother nor my father. I felt

alone. I remember seeing a flash of bright white light and the fading scream of a Yanluo mixed with a twelve year old girl. Angelica. The scream

died out, I felt my bonds weaken and then disappear. I remember looking around the room, looking for Angelica. But I couldn't find her. I

remember seeing a pool of scarlet red blood before losing conscious. To this day I still don't know if what I heard and what I saw, was a

hallucinations or not."

The others had gone pale. "There, I told you. Happy with the story because I am not telling it again."

"I…had no idea you went through that much. I'm sorry I made you relive it all over again." Charlotte said softly. I stared down at the floor.

"What was she like? Your sister, Angelica, what was she like?" Cecily asked. I gave a small smile and smirked.

"What was she like? Her Chinese name is Daiyu. Well, she was a good Shadowhunter, she loved to draw and read, she could play the flute, harp

and violin, and she could make anyone smile and laugh. She was my best friend. She could also sing very good, too."

"Wait, aren't twins for Shadowhunters extremely rare, as in it's never been done before." Will asked. I nodded. "So then how could you be twins

with Angelica?"

"Well, we share the same birthday and we are both the same age. We share the same parents and look almost identical. We were also born just

minutes apart. I'm the older twin." I said.

"Does the Clave know about you and your sister?" Charlotte asked.

"I don't know. I think the clave in Shanghai knows, but I don't know if the Clave in Idris knows or not."

"Anyway, so do you know where Yanluo is or not." Gabriel asked. I shook my head.

"He disappeared along with my sister. But if we had to start some where, I would say the institute where he was last seen."

"I agree. It does seem like the best option. All in favor say, Aye." Says Henry.

"Aye." Gideon said.

"Aye." Gabriel said.

"Aye." Charlotte said.

"Aye." Will said.

"Aye." Cecily said.

"Aye." I said.

"Perfect. We are going. I will alert the Enclave and then we will go." Slowly, everyone left the library to go prepare. Soon the only ones left were Tessa, Will and I.

For a while we all stood (or sat) in silence. Then Tessa spoke up.

"Where do you think you sister went?" she asked. I looked at her. My wife. I couldn't keep anything from, as much as I wanted to.

"I believe she is dead." Tessa looked shocked by my answer. As did Will.

"Why would you say that? Don't you want to see her again?" Will asked.

"Of course I want to see her again, but I don't want to set my self up for a false hope. I haven't heard from her since that night."

"Heard from her? What ever do you mean?" Tessa asked.

"Well, Shadowunter twins are well extremely rare. We can do things that no other shadowhunters can do. We have a mental link between us, like we share

thoughts and can communicate telepathically. The bond between us is similar to the Parabatai bond, but stronger."

Will mouthed Oh. And they fell silent. They were staring at me.

"What did she look like?" Tessa asked. I looked at her.

"She was beautiful. I mean, she was only twelve, but I knew my parents weren't going to have any problems finding a suitor for her. Her hair

fell a little below her shoulders. Her eyes were hazel, but a little more on the green side. Her face was round. She had a great smile…" I trail off.

If she were still alive, would she even recognize me? We used to look so similar, but now…

I snapped out of my thoughts by Will, saying something obnoxious, as usual… "So, if your sister is a live, do you think she would fall for me?"

I roll my eyes. "My sister wasn't stupid, Will. Even if she had a shred of intelligence, she would know you were trouble from a mile away." Will

frowned.

"Well… We better go pack. Charlotte will want to go as soon as possible." I say, getting up. I get some nods and we go our separate ways.

And that's when I felt it...

So that's my first Chapter. A little long, but oh well. Comment, Review or whatever you guys do best... please...
