Chapter 1: Missing

Clary's Pov

Its been two weeks since Jace and Sebastian has gone missing. The only real proof that I have that he is still alive is the fact that Alec's parabatai bond is intact. I know Sebastian must still be alive because of the attacks. All across the world, downworlders, shadowhunters, and warlocks have been disappearing since about a week ago. My best bet, and the Claves, is that it must be Sebastian. They also believe its Jace's. But after seeing Jace being possessed, I know it would have to be against his will. Right?

Shaking that thought out of my mind, I opening the glass case. I struck a deal with the Fairy Queen. I'll get her communicating rings -which were on presentation in a glass case in the library at the Institute- and in return she'll give me information about Jace.

I hear the door open to the library and I turned around to see who it is. And felt my blood run cold.

Standing there in the flesh, was the one and only Valentine Morganstern. I was so shocked I couldn't move. Beside him was Sebastian and Jace. But that wasn't what I was focusing on.

'How is he alive' I thought' I killed him'.

Immediately, I dropped down to the ground. I heard them enter the library.

"How long do we have" asked Sebastian.

"As long as we want." answered Valentine.

"But they are going to come ba-"

"Jonathan. Don't let your self be undermined by those pathetic excuse for a shadowhunters. If they do come back, then we'll handle them" Valentine chimed.

"I said call me Sebastian" he said, but Valentine either didn't here him, or chose to ignore the comment.

Handle them? What the hell are they even doing here in the first place? As silently as I could, I crept over to the banister and looked down to see them looking though the book shelves. Jace looked fine. He was fine. But why was he with them.

"Look on the next level Jonathan" is what I would have heard Valentine say if I wasn't so rapped up in my mind.

"Well look what we have here" said a familiar voice. A second later I felt someone grab me by my hair and throw me against the glass show case.

I staggered to stand up but my legs gave out on my. I touched my head and felt something liquid.

Blood.

"Are you alright little sister" Sebastian growled.

"Go to hell" I growled back.

"Already been there. Its better than you think"

"Stop talking ass-hat" I mumbled, all the energy starting to drain out of my body.

"Whose that and why are they still breathing" Valentine's voice boomed.

He was stomping tword us with a look of pure rage on his face, with Jace right behind him.

"Its your sorry excuse of a daughter" Jace smirked.

I felt my heart skip a beat. Did he really just say that? I started to scoot backwards. I didn't realize it till now; the glass had broke when I hit the case. All I know that there was blood and glass everywhere and me shuffling around in it wasn't helping.

He must be pretending. Or something like that.

"So what are we going to do with you" Sebastian mumbled, tilting his head to the side. Before I could say anything, Jace grabbed my arm and hauled me to my feet. The last thing I saw before everything went back, was Jace's hatred filled eyes.

Why is Jace acting so weird?

What the hell is his problem?

Find out in the next chapter. Or not. Wha-ha-ha-ha-haaaaaaaaaaaa.
