Hello!

As mentioned in the summary, this is my attempt at writing "city of heavenly fire". Hope you'll enjoy, and make the wait for the real book a bit shorter. (A couple of seconds).. ;)

Anyways, this is a short starting chapter. If you want more, I will post more I guess :) Enjoy!

Disclaimer: I do not own the mortal instruments, and I am not Cassandra Clare.

Clary was sitting in Isabelle's room in the institute, clothing in piles on her bed and chair, lacy bra straps were peeking from drawers and weaponry was scattered around the room. Isabelle herself was seated on her bright pink bed, legs crossed and her hands in lap.

"So did you and Jace work things out?" she asked Clary, while reaching for a mug of coffee that sat on her bed side stand. Clary nodded, not wanting to elaborate her conversation with Jace. Some things where just private.

"Even though the clave has already down prioritized finding a cure for Jace" Izzy continued, "We could still look for one. We'll have Magnus to help us."

Clary didn't really know what to respond.

"Maybe we could talk Raziel into taking his heavenly fire back" she sighed, raising the mug to her lips.

"That's just a bad joke"Clary responded. "To change the subject, you must have a lot on your mind."

Isabelle shot her a quizzical look, and Clary rolled her eyes.

"That's my coffee your' drinking."

Isabelle looked down at the mug, like she was in denial of it being there. Then she shook her head and put the mug back on the bed stand.

"Sorry."

She then got up, and started searching for something in her messy drawers. When she remained quiet, Clary didn't ask what she was thinking. She, herself, had a lot on her mind.

Moments ago, she had been with Jace, in the institute's infirmary. They had talked, sure enough, figured things out. But it didn't change the fact that Jace was different now.

She, Clary, had done something to Jace with Glorius, the sword Simon had received by summoning Raziel. It was meant to separate Jace and her dark demon brother, Sebastian. And it had. But the fire of the sword, burning with a golden glow, had somehow transferred into Jace's body, making it awkward and stinging to touch him, even the slightest. She wasn't sure what it meant.

And the fact that Sebastian had gotten away once again, was not at all comforting. She hated her brother even more now, if possible, for hurting her Jace. For hurting Luke, his sister, for hurting her mother and for trying to hurt close to every being alive. She did actually catch herself in wishing he would come back for her, so that she could end it. Kill him. But of course, when this was what she wanted, it wasn't going to happen. Meanwhile, none of their attempts to track Sebastian had worked, even though Clary had destroyed his 3 dimensional flat, the night she stabbed Jace with the angel sword.

She couldn't help but think about her brother. His eyes so black, his pupils hard to distinguish, hard and cold. The blood of a demon ran in his veins, and it showed. He wasn't capable of feeling, of loving. Spending time with him, she had come to learn that Sebastian always faked feeling. Every happy laugh, every smile, was just fake. This was what Clary told herself. But there was a seed of doubt in her head. She had seen the change. When Sebastian had let his façade down, when Clary had told her she felt nothing for him, she had seen the loneliness in his eyes, along with the bitterness. Was one capable of feeling alone, if one was a demon?

"Hey, Izzy, I was wondering…" Clary began, but was interrupted by Isabelle's bedroom door opening quickly, revealing Alec. His jeans were torn at one knee, the edges of the fabric bloody, a fading iratze visible. Wearing only a grey t-shirt, his arms where filthy dirty, and covered in blood, as well as his hair and face.

"What in the Angels name have you been doing?" Isabelle demanded from under her bed, where she was currently searching for who-knew-what.

Alec, still standing in the door, his expression dark, didn't answer her question. Clary noticed trail marks under his cheeks, marks that came from crying. What had happened to him?

"Sebastian sent us a message." He explained.

"Sebastian?! What was it? What did it say?" Clary burst out. Isabelle was staring at her brother in disbelief, pausing her searching quest.

Alec took a couple of steps into the room, and with a sigh, sat down in a chair opposite Clary. Isabelle, looking worried, went over to sit on her bed. Alec was looking very distracted.

Clary shot Isabelle a questioning look, but Isabelle just shook her head, very slightly.

"Alec?" Isabelle tried.

Alec seemed to jump out of his trail of thoughts, his expression very odd.

"Sorry. As I was saying, he sent a message. Here at the institute. Maryse was the one who found it, and contacted the silent brothers.."

"So what did it read?" Clary asked impatiently, Isabelle shooting her a warning look.

"erchomai - I am coming"

Clary felt the blood drain from her face, and was about to reply, but then Alec continued.

"He sent us something along with the message", his voice barely a whisper now.

Clary's spine was giving her weird chills, and Isabelle was looking very white.

"What?" Clary whispered, knowing she really didn't want to know what he had sent them.

" A pair of Angel wings. Torn from a live angel." He told them. Then the 3 of them just sat in silence, listening to the rain pouring down outside.

This was the kind of sickness that her brother was responsible of. This was how big a monster Sebastian was. Clary could nearly hear Sebastian's voice in her head, as she crossed the room to peer out of the window. Erchomai – I am coming….
