Warning: if you have not read City of Glass or any of the books after there are a few slight spoilers in the first paragraph. After that though, you're good.

Since meeting Jace there have only been a few nights when I slept soundly. In fact I can count those merciful nights on one hand. The first was the night was the first night I spent in the infirmary at the Institute. The second was the night Jace snuck into my room in Alicante. And the third, the night Jace and I found out we weren't siblings. The last is iffy at best, what with all the other issues we had to deal with, but it was a little relief in itself.

Realize that every single one of those nights was related with Jace. I'm sure you caught it, I just thought I'd point it out.

Anyway, tonight was no different. I had woken up twice in my bed at the institute already, but each time I woke with more and more anxiety. It was building, getting worse. This time I gasped awake, drenched in sweat. This I was used to though. I was always particular about the temperature of my room, it had to be cold. And I do mean cold.

I leaned against the headboard heaving in gasps of frigid air. This needed to quit. What I realized soon after the restless nights started was that everything gets harder with little sleep. Everything.

That was the last straw. I went into the bathroom connected to my room and washed my face. It always helped me relax and refocus. I looked at myself in the mirror, seeing the sleep lines and dark bags that I had grown accustomed to seeing were deepening and darkening.

Without a second thought I slunk out of my room, down the hallway and into Jace's room. I was careful to look around, make sure no one was watching. Not that I much care what they think, but this really didn't give off such a good image of me.

Once inside I quietly closed his door. A shock went through me as I turned too look and I almost screamed. Jace sat cross legged on his bed watching me calmly in the dark. "Come here often?" Jace said slowly.

"By the Angel, Jace you scared me."

"I can't say that anyone has ever said that to me. It's almost always 'By the Angel Jace, you're stunningly attractive' or 'dazzlingly hot'."

His sarcasm, while almost always annoying, was something I found comfort in now, as in other times of stress. It's a normal place to be, a relaxed, easy place. I stumbled over to him, my bare feet scraping against the rough hard wood. He opened his arms wide and I let myself fall into him, slumping against him as much as possible. "Another rough night?" He said into my ear, lovingly concerned.

I snorted into his shoulder, "How could you tell?"

"I heard you all the way from in here. You kept knocking into the wall as yous slept. I was just about to go in and wake you when you came in."

I must seem so weak to him. Pathetic. I groaned. It's a good thing Isabelle and Maryse were in Alicante finishing up business and Alec had taken to staying at Magnus'. I realized there wouldn't have been anyone to see me come into Jace's room, so my sneaking was for nothing. Like I said, without sleep everything gets harder. That includes thinking.

Jace leaned back, pulling me with him, so that I remained on top of him. "Come on, then." He whispered when I resisted slightly. I relaxed and let him pull me down. When he was settled I was leaning on my forearms, which were resting on his chest, and looking down at him.

His index finger slid along the top of my nose, gliding down to my cheek bones, moving on to my eyes lips and cheeks, tracing and teasing. Enticing.

His eyes remained on mine, and his smile, though faint, coaxing one out of me as well. Both our smiles were small but content and lazy. Again he made it seem as if he could do anything and make it seem easy.

After a while my eyelids began to droop. I fought it. "Go to sleep. I promise I'll be right here when you wake."

I shook my head, half knowing I probably looked like a stubborn child. "No."

He stretched his head up, touched my nose with his and against my lips he said, "I promise."

It made me want to, I'll tell you what. The way he said it was seductive and enticing. I leaned forward as he leaned back. His head hit the pillow and my lips hit his as it did so. He complied, pressing his lips against mine. Both his hands rested against either side of my head, his thumbs latched behind my ears as he pulled me closer. I fisted his shirt. I didn't think it was possible to get any closer, but hell if I didn't try.

He released me a while later, running his fingers through my curls. "Was that enough?" His voice was proud, like it surprised him that he could have that kind of effect on me.

"Never." I leaned in again but he stopped me. Leaning his head he kissed my throat lightly, kissed my cheek and finally my nose.

"Sleep."

His hands directed my head to his chest but this time I didn't resist. I released his shirt but left my hands were they were.

Hoping he would hear me through my sleep-slurred voice I mumbled, "I always wanted a guardian angel and now I have one."

I felt his chuckle against my cheek. "And now, so do I."

A/N: I hope you enjoyed it! I know I did while writing it. What can I say, I'm hopeless! More coming, but it might be a while. Most likely this won't be a continuous story but more a collection of one-shots, unless circumstances change. Please review or send me a request!
