Hi this is my first attempt at writing a book ever, so comments and advice would be great because I'm not exactly sure what I'm doing!
...
I sat myself down into my plane seat with a pleased sigh. Finally, I would be going home. Two weeks with my Aunt and Uncle didn't sound like much, but if you'd met them, you would have been driven crazy after the first weekend. Somehow, I stuck it out. The plane flight from the Caribbean back to the UK would take 36 hours. I was in for a long trip. I wasn't that comfortable with flying- a plane seemed too big and heavy to rise up and carry people into the air. However, I'd been on a plane before, and that was with my parents. Sure, I was on my own this time, but how hard could it be? Look out, England- Georgina Buckley is coming back!
A sudden jolt woke me up. I'd been napping, and now we were high in the sky above the clouds. The plane lurched again. I gripped hold of my seat firmly, as if holding onto it hard enough would steady the plane. A low murmur was spreading through the cabin; whispers of worry from those who were afraid of heights. An air-hostess entered the cabin, smiled and announced that we were experiencing some turbulence. She assured us not to worry and that it would be over within a few minutes, but asked us to please strap ourselves in for safety measures. I pulled the belt across me and snapped it into place, keeping hold of my seat. I tried not to pay attention to the thought that if we were safe, then why were we strapping ourselves in? The plane jolted again, more violently than before. Someone cried out. A look of anxiety fleetingly crossed the air-hostess's face as she, too, strapped herself into a seat. Whenever a member of staff does that, you know something is wrong.
Suddenly, the plane started to jolt and shake. Drinks spilt, hand luggage fell down and emptied onto the floor, and panicked cries filled the cabin. My head snapped back as my body fell forward, stopped by the safety belt. I didn't scream. I had a feeling things were about to get worse. I looked out of my window and saw flames. My breath caught in my throat as I realised that one of the engines had caught fire. I started to panic. Then I screamed. I screamed as the plane plummeted out of the sky. I screamed as the deep, dark blue ocean rushed up to greet us. I screamed as the plane hit the water and sank beneath the waves.
Silence.
Then water started to trickle in through the windows, the view outside a cold, unwelcoming sight. Then someone screamed. People started shouting again, tugging at their safety belts. The water was up to my ankles, and rising, swiftly. It didn't even occur to me to try and get out of my seat, even though the belt was cutting sharply into my stomach. I felt sick, my stomach churning uncomfortably. I glance round. I felt like I was in a trance. Everything seemed distant, unimportant somehow. A baby was crying, its mother yelling for someone to help her and her child. Everyone ignored her, only thinking for themselves. The water was up to my knees now.
I thought about phoning for help. Yes. A good idea, phone for help, do it now! I pulled out my phone, and stabbed at the keypad. My senses seemed slower. I struggled to dial. Three numbers, and I couldn't even type them in.
Then the man on my left decided he didn't want to sit there like a waiting target. He got up, and struggled to get past me. I pulled my legs up onto my seat to let him through, the water rising to my waist.
The man was panicking, and shoved past. His flailing hands knocked the phone out of my grip and into the water. I reached down for it, my arm sliding into the water, up to my chest now. I couldn't feel the phone.
Then the water reached up and over my head. I had time to take a deep breath, and then the cabin was filled with water.
It was strange sensation. Every sound was muffled as the water filled my ears, and my eyes stung with saltwater. The plane sank. I saw people trying to swim to one of the doors, to get out of the plane. Luggage was floating in the water. A white shirt was bobbing near me, the sleeves stretched out like a white ghost reaching out to claim victims. I knew that now was the time to get out of my seat, but couldn't. I glanced down at my seat belt, keeping me trapped. A prisoner in this watery jail. I tugged at it, trying to pull free, so I could swim, swim for safety, swim for air. It stayed put. My hand found the release button, and I pressed it. The belt came unattached. I pushed myself out of my seat. My body felt as heavy as lead. Other passengers were swimming to the door and trying to force it open. I looked around and felt a chill as I saw people sitting in their seats, trapped by their 'safety' belts. Not moving. I started panicking, and large bubbles of air streamed out of my mouth. I clamped it shut, just as the plane's door was forced open. The cabin quickly emptied as survivors swam to the surface. I forced myself to swim, up and out of the plane, towards the sun. It was there, above the water, along with sweet, sweet oxygen. But then, stupidly, I coughed. The last few bubbles of air, the thing that was keeping me alive, escaped my mouth. I choked as the water rushed in, filling my lungs. I slowly sank, the sunlight fading fast. I was going to die.
As I sank, deeper into the darkness, deeper into the depths of despair, I felt a sudden calmness wash over me. I let the water enter my lungs. I stopped thrashing about, stopped writhing and flailing. I just sank, silently, swiftly, smoothly. Maybe it was better this way. A pleasant way to die. I closed my eyes.
'But why?' A small voice in the back of my brain whispered. 'Why die now? Here? Rather silly, really. This is stupid and pointless. So swim. Now.' My legs kicked of their own accord, my arms reached for the sunlight.
My head broke the surface, and I gasped a delicious breath of air. I was alive!
I looked around, gasping, the water slopping into my eyes, mouth and up my nose. I coughed and spluttered, treading water. I glimpsed others doing the same thing, some screaming, some crying.
'Don't think about them,' the voice screamed. 'Think about you!'. It was right. I twisted my head around, looking for something to grab hold of. I wasn't an especially strong swimmer. I spotted an empty suitcase, bobbing on the waves, and splashed over to it, grabbing hold and clinging on tight. My hands were shaking and my body was covered in goosebumps. I was freezing. Blinking water out of my eyes, I saw other survivors fighting over bits of wreckage. There were only forty or so, plus me. The plane had held at least three hundred. Tears welled up and spilled down my cheeks. What were we going to do? I couldn't see any boats nearby. There was a small stretch of land in the distance, but I might have been imagining it.
What were we going to do?

I loved the imagination you brought into it. I think the beginning could have more information. Why was the character travelling alone? Who is the character? Things like that. I also think that you could describe things more so that I can picture it. I suppose you're going to continue it and I think you should! I loved the first and I hope I'll love the rest.
