Chapter 1

After the bond between Jace and Sebastian was broken, there were several horrible days for Jace Lightwood. He was questioned about Sebastian's plans and about the Heavenly Fire and pretty much everything. But he never answered any of those questions. He just sat in his bed, his had rested on his knees just listening to different members of the Conclave or to the Silent Brothers. Since his return, he didn't say a word. Not even to Clary.

As Clary entered the Institute, a new wave of sadness embraced her. She wanted to go and talk to Jace, to make feel better, but it was pointless. It was like he wasn't listening to anything, anyone. Where was the boy that she loved so much?

"Clary, you're here early", Isabelle said, appearing in the hallway.

"Yeah, I couldn't sleep or anything with… this situation."

A sad smile crossed Isabelle's face. They've all been in pain since Jace was back, but he was not Jace.

"The Silent Brothers stayed with him all night and tried to make him talk, but nothing. They said that maybe the Heavenly Fire destroyed his soul."

Isabelle's voice was filled with so much pain. Jace was like a brother to her and Alec and she didn't want to lose him too.

"No, no. This can't be possible. Jace is more powerful than that."

"Clary, maybe they're right. No one knows the powers of the Heavenly Fire. Maybe it's too much even for Jace…"

Clary was filled with anger. Not towards Isabelle, even though she was very wrong. She couldn't understand how the Heavenly Fire saved Jace but stole his soul. It was impossible. Jace was more powerful than that and she knew it. Maybe in time everything will change. After all, he had been through a lot.

"I'm going to see him," she told Isabelle, going towards the stairs.

When Clary entered Jace's neat room, she saw the Silent Brothers staying near a boy who seemed to be very young. His golden hair covered most of his face and she could see only those beautiful eyes of him. He was sitting in a corner of the bed like he was trying to get away from the Brothers. Like he was afraid of them.

Clary saw the Brothers leave the room wordlessly. Probably they were as hopeless as them. No one knew what was wrong with Jace.

"How are you feeling?"

She tried to put a hand on his bandaged arm, but he retreated his like she was a demon. Clary tried to keep her composure and sighed.

"Jace, I know what you've been through but you can't keep going on like this. We need you so much right now. Alex needs you. I need you."

No reaction. Nothing.

"Do you even know that Alex is sick? He's been like this for the last few days. He said that the Parabatai bond hurts him."

Not even mentioning his Parabatai changed something in Jace.

Suddenly, the door hit the wall and Alec busted in, followed by Isabelle. He didn't even observed Clary, like he was dreaming. He jumped on the bed with all his force and faced Jace.

Clary looked at Isabelle, but she was as clueless as her. Alec has been really sick for the last past days. He couldn't even get out of bed or speak too much. Now he was walking like nothing happened.

Maryse entered the room, followed by the Silent Brothers.

"Jace," it was only a whisper coming from Alec.

Alec was facing Jace, with his hands on his Parabatai's knees. Their eyes locked and it was for the first time Jace really looked at someone. Then something really weird happened.

Jace's whole body started to lighten up, like it was fire surrounding him and that light enveloped the two boys. And then Jace smiled and Alec took his hands.

"What's going on?" Clary whispered.

"I haven't seen anything like this. I only heard by stories like this. It's the parabatai link. There was another Shadowhunter, long time ago, who had the Heavenly Fire inside him. The Fire is very powerful and destroyed the Shadowhunter, but is believed that the parabatai bound makes it bearable," Maryse explained.

"You mean… They share that power through their bond?"

"Yes, Isabelle. It's amazing."

Clary moved her eyes again towards Alec and Jace. They hadn't moved and they were looking at each other, like they were talking. Then, the golden light retreated back in Jace, making him close his eyes and Alec turned back to them.

"He needs to rest a little bit. I'll be in the library in five." Alec announced.

As she exited the room, Clary saw Alec making Jace more comfortable on the bed.

"I can't believe that their bond is so powerful," she whispered to Isabelle.

"Yeah, it's pretty amazing, but we don't know what the Heavenly Fire does to them. It scares me that all that power can destroy them both."

Clary just nodded. She knew that it was painful for Isabelle to see Jace like this, but it was even worse to see Alec ending up just like Jace.

Five minutes later, Alec entered the library where pretty much everyone was waiting from him. She smiled to his sister, trying to reassure her and then he took a sit on one of the old Victorian chairs.

Tell us what happened, Brother Zachariah said, lifting his head from the meditative stance. The hood was still covering his whole face and Clary wondered how his face looked like once more.

"I could… talk to Jace. I mean, I could hear his thoughts or something like that. He told me that the Heavenly Fire was burning his insides, that he couldn't control it. And he also told me that Sebastian is coming."

All eyes were on him now. Everyone was shocked.

"What? For what is Sebastian coming?" Maryse inquired. She always feared Sebastian, like everyone in the room.

"For Jace." Alec explained. "Somehow he knows how he can control the Fire. And the Heavenly Fire is the only thing that could kill Sebastian."

"So we must find out how can Jace learn to control it." Isabelle said, looking at her brother.

"Basically, yes. But Jace's not talking to us, so what can we do?" Maryse's voice was filled with pain as she watched the sky from the window.

"He told me it's too much pain. He can remember everything he did while he was with Sebastian. He also told me that…" Alec hesitated for a moment, trying to say those painful words. "We should kill him before Sebastian comes…"

Everyone was petrified. Clary couldn't believe what she heard, as well as the others. Even the Silent Brothers looked surprised. She had just saved Jace from death and now they were supposed to kill him.

No. There had to be another way.

What do you think? It's worth continuing?
