This is my first attempt at a fanfic, so I would really love to hear what you think! ;)

Here's a slightly longer synopsis, if you're interested:

Amelia Sully is shocked when she hears her brother is responsible for the disastrous defeat of humans on Pandora. When she is approached by government officials, who think she might be helpful in re-establishing a negotiation basis on Pandora, she is torn and confused. Traveling to Pandora to meet the brother she hasn't talked to in more than seven years, she asks herself if she will ever be able to understand why he did what he did and whether there is any hope for her own dying planet.

In alternating chapters a second storyline follows Amelia during the time before Jake leaves for Pandora. One fateful blow after the other tears her family apart and she wonders whether she will ever be able to find happiness in this world. A good-looking, warm-hearted collegue at University finally gives her a sense of hope.

"Hey Amelia!" I heard Pat's voice carrying from the small common room across the narrow, dark hallway into the tiny kitchen. My hands were submerged in a sink full of water, soap and dirty plates. "You're on TV!" he continued "Come on, you'll want to see this."
I sighed quietly, recovered my hands and found a towel to dry them, making my way towards the sound of the television.
"...official reports are still unclear as to what happened exactly..." I frowned. The screen showed footage of the RDA mining stations on Pandora, alternated with government officials talking. Nothing unusual there. "What's going on?" I asked, mildly interested.
"War on Pandora!" Dereck, who was sitting next to Pat on the tiny couch, announced dramatically. My eyes widened a little. "What?" I asked incredulously. Reports of tensions on the distant mining station had been omnipresent over the last several months, but full-on war was something different.
"And we already lost it..." Dereck continued "...looks like it was short and painful."
I swallowed. "So... what does that have to do with me?" I looked at Pat, who had called me before. "Just wait and see!" he urged, his eyes fixated on the screen.
"...the devastating defeat was largely caused by an organised insurrection from within the structures of the RDA itself. According to RDA spokesman Peter Harris a group within the RDA's science department had turned against the Administration and assisted the natives in a plot against its advances. When tensions escalated they supported the natives in their attack on the RDA mission and their insight into RDA structures and military organization are likely to have facilitated the disastrous outcome. A list of the individuals involved in this plot of high treason will be made available in due time. What we know at this point is that the group centered around a man named Jake Sully, who is believed to have led the attack. No official numbers of casualties have been released at this point but they are expected to be in the thousands."
I felt a blinding dizziness beset me and tried hard not to let it show. Pat grinned at me. "You don't happen to have any distant relative by the name of Jake, do you?"
I swallowed hard. "No, I don't" I said and tried to fake a litte laugh. That was true. I didn't have a distant relative by that name. He was my brother. But none of my collegues would ever think of asking me that, since I had told them I was an only child.
"Well Sully's not that common a name..." Pat continued and seemed slightly disappointed. I shrugged. "It's not that uncommen either..."
The voice in the TV continued. "... the failure of the mission will have far-reaching consequences for all of us. Cut-backs and further restrictions on electricity and water supply are expected, as well as..."
I blinked a couple of times, trying to force back the sick feeling that was developing in my stomach. I couldn't think with all my collegues in the room.
"I'll be out for a couple of minutes!" I told them and left the room. Heading to the dark, tiny cubicle that was Eloise's and my room I had a hard time keeping my balance and not stumbling over my own feet. I grabbed for my grey protective breathing mask with shaking hands and wanted to head back out, when I ran into Pat in the tiny hallway. "Hey, what's wrong?" he asked and his forehead creased with concern.
I raised my eyebrows at him. "What's wrong? We just lost a war, with thousands of people dead and there'll be more restrictions on God knows what and I don't even want to think about what else they're going to come up with now." And it very much looks like all that is to a significant part my own brother's fault, I added in my mind.
Pat reached out and put one hand on my arm. "Don't worry so much, Am! It'll be fine, I'm sure! They'll find some other way... to..." He wasn't really sure what to say and I took the opportunity to squeeze past him and head towards the door. "I'm sorry, Pat, I just need to get out of here" I said turning back. He nodded. "Why are you always wearing that thing?" he added, pointing to the mask I was just putting on.
I gave him a hard look. "Oh I don't know... maybe because my mother died of lung cancer..." I mumbled angrily and escaped out the door. "Right, I'm sorry!" I heard Pat's voice call after me as I stepped out the door and pressed the button to the elevator. I got into the tiny metal confinement and once again wondered, how we were not all going insane with claustrophobia.

I stepped out into the street and it was raining. The large dorm room tower of Central University was situated close to the centre of the city, so it only took me a few minutes to reach Central Square. I regretted that I had come the moment I looked up to the huge screen overlooking the square.

"Traitors bring about massacre on RDA mining station on Pandora"

It said in huge glowing letters. I tried to breath through the confinement of the mask, but my lungs only received my own hot breath. When I felt I was close to passing out I pulled the mask from my face and took a deep breath. I might as well die now, I thought grimly. Now that I had apparently lost the last member of my family. I continued my slow progression along the main street. Closely surrounded by thousands of people, bodies pressing against mine, I felt utterly lonely. When I could no longer bear the close proximity I escaped into a side alley. Before I had moved to the City to go to University my mother and brothers had repeatedly made me promise that I would never leave the main streets on my own. "Those side alleys are literally biotopes for criminals." Jake had said. I didn't care now. My mother was dead, Tommy was dead and Jake had apparently betrayed the whole human race and me along with it. I felt a single tear finding its way down my cheek. I didn't understand the world. Jake had always been somewhat rebellious when we had been younger, but this...? Why he would do something so horrible, I could not fathom. Thousands of people dead... I shook my head to drive away the thought.
The alley I was walking through was dirty and a sickening stench clung to the dark concrete walls. It looked like a good place to die, I thought and realized that more tears were washing down my cheeks.
"Hello young lady!" I heard a greasy voice and almost jumped when I stared into the face it belonged to. "All alone?" A man with a huge, dangerous grin, that revealed only half of the teeth a normal human possessed, stood behind me.
"No" I said firmly "actually, my friends are just over there." I pointed towards the other end of the alley, praying to God that it led to a major street and not another dark alley. And then I just turned and made a run for it. There was a street on the other end that was lightly populated and I panted with aching lungs as I reached it. So much about wanting to die, I thought, wiping away the remaining water on my cheeks.
Then I turned my head up to see which line of the sky-train was nearby and made out which direction I had to go into. Hesitantly, I put the mask back on and walked with more determination, back to Central University. Jake had been gone for almost seven years, I thought. I've been fine without him for all that time, I would be fine without him now. He had left my life a long time ago and he would not enter it now. Nobody had to know I was the traitor's sister. If only nobody would find out, I prayed silently as the University Tower came into sight in the distance and I felt thousands of bodies pushing and shoving against me for the millionth time.
