This is at the end of City of Glass, when Jace, Valentine, and Clary are at Lake Lyn and Jace is killed. It's what I think could've been happening to Jace during this time. JACE'S POV.

Disclaimer;; Unfortunately, I do not own The Mortal Instruments series or any of the characters. If I did, Jace would be mine. I also do not own the first two sentences of this fanfic. These things belong to Cassandra Clare. (:

It was the Mortal Sword. It left a tracery of black light on the air as Valentine drove the blade into Jace's heart.

I looked down, uncomprehending. The Mortal Sword stuck out of my chest, but I couldn't feel it. It was held by the man who I thought was my father. I looked up at him, unsure of what to do. I saw him are move, and I was on my knees.

The pain I felt was all that I knew. I clutched at my chest uselessly and my hand came away red. I didn't waste energy to look at Valentine again; instead I looked at Clary. I tried to say her name but all that came out of my mouth was blood. My blade fell out of my hands. Then I fell. Everything went black.

Everything was white.

I blinked as my eyes adjusted to the brightness. Where was I? Was I dead? If so, where were the pearly gates? Or maybe I was in Hell. If that was the case, where were the pitchforks and fire?

None of it made sense. I had died. Valentine had stabbed me with the Mortal Sword to get the blood he needed to bring the Angel out of the water of Lake Lyn. I… I should be somewhere, not here where there was nothing but white.

I looked down at myself. My clothes were dirty and bloodstained, but there was no rip in my shirt above my heart. Frantically, I lifted my shirt up. I saw nothing but smooth skin and black runes. Not even a scar.

"What happened?" I murmured out loud.

"Just what you think happened, Jace."

I swiveled around quickly, raising my arm defensively only to find out that I didn't bring my Seraph blades with me to this place. Apparently, I didn't deserve the Heaven I wasn't sure I believed in, so therefor I didn't deserve a weapon in the afterlife, either.

"Relax, it's just me." The words were accompanied by a childish giggle, and a small figure appeared in front of me.

"Max?" I asked, my eyes widening. The youngest Lightwood smiled. I stared at him, and he ran over to me to give me a hug. I wrapped my arms around him, wondering if I was hallucinating.

"So I'm dead." I said finally.

"What makes you say that?" Max asked. I shrugged.

"We'll, um, you're here." I grimaced. I still couldn't comprehend that energetic little Max Lightwood was dead.

"Why would that mean that you died too, Jace?"

I blinked. "I'm…not?" Max shrugged. "Does everybody come here?" I gestured tot eh whiteness around me. I wanted some real answers.

Max shook his head, smiling mischievously. "Nope. You're a special case."

I started pacing then. A special case. What did that even mean? Did I have to stay in this place for the rest of eternity? If so, why was Max here with me? "So, now what?" I asked, looking back at Max. "What happens now?"

"Now we wait."

For what? I wanted to scream. There was nothing to wait for. This place was empty. Empty except for a dead Shadowhunter and a child. And white.

I stared at Max. he was twiddling his thumbs, humming a melody I'd never heard before. He had his eyes closed and he was smiling peacefully.

"What's Heaven like?" I blurted, unable to help myself. Max just shook his head. I sighed, and I waited. I didn't know what I was waiting for. "How long has it been?" I wondered out loud.

"Not as long as you think," Max replied cheerfully before going back to his humming. I frowned and looked around, wishing I could sit down. As soon as the thought crossed my mind a white chair appeared next to me. I shrugged to myself and sat down. Wherever I was, the service was quick.

Max's smile spread to a grin and he opened his eyes. "You might want to stand up."

Grumbling, I did as he suggested. Suddenly there was a flash of gold light so bright that I had to close my eyes. When I opened them, I couldn't believe what I was seeing.

"By the Angle," I murmured, falling to my knees. Raziel, the angel that created the Nephilim, was standing right in front of me, smiling at me.

"Jace," he said gently. "Jace Herondale. Come with me,please."

I glanced at Max, who was smiling, his eyes shining with tears. "Go," he told me, "Tell my family that I loved them. And I love you too." I nodded, and then looked at Raziel. He smiled and nodded, extending his hand. As soon as I took it, everything went black again.

I felt something solid under me. I could feel the fabric of my clothes. But - and I couldn't explain it - I didn't feel whole. I wanted to see Clary. I wanted to make sure she was okay. I also wanted to find wout what Raziel had done and where he had taken me.

My main focus, though, was Clary. I called her name in my head. Clary! Again. ClaryClaryClary, over and over. Finally I forced my eyes open.

I was lying on the shore of Lake Lyn. I felt my chest – there was a whole in my shirt, but my skin was smooth. Just like it had been in that white place.

I rolled my head to the side, and my mouth actually opened in a silent gasp. A red-haired girl was lying next to me on the sand. I sat up.

"Clary," I said quietly, "Open your eyes."
