getDare Truth or Dare - Shades of Darkness- New story idea

Ok- I will post the story here- if anyone doesn't like it then please say so. Please note it will be a long story when i have finished it.
So here we go with Part 1:

There was no time to do anything, not even scream. It was closing in on her. She had no way of escape. The pitch-black shadow loomed over her. A flash of pure white light lit up the room. The shadow let a bloodcurdling scream and vanished.
With her eyes still stinging from the flash, she looked up to see a boy wearing goggles looking down. "Are you all right?"

Astrea was 16 years old. She was about 5' 9" with a tanned slim figure and shoulder length dark red hair. She had lived in section 4 all her life. Towns and cities were divided into sections with the richer people closer to the center of the city and the poorest people closest to the edge. There were 5 sections in Moonflower city but no-one lived in section 5 anymore. A chemical leak had wiped all of the inhabitants out all apart from the resulting mutants. She was walking to the market to get some breakfast, when she noticed that she had left the little money she had at home. She turned round to try and head back but a market cart had tried to do a 3 point turn in 2 turns and had blocked the street. She spied a passage on the left that would lead to the section's main circle. The passage was quite narrow and dark with it getting darker all the time. She kept walking until she saw a light up ahead and ran towards it.

She was horrified by what she saw. This was section 5. She had to get out of here before the mutants came. She span round frantically but the passage way was gone.

She ran towards the nearest building to hide. She ran in, shut and bolted the door. She sat down on the floor catching her breath. She didn't have time to fully rest as a dark shape was sliding under the door. She scrabbled backwards away from the door, away from the forming shadow. She looked round for a way to escape. There was only the door from which the shadow was coming. It was looming over her. She knew it would kill her. She closed her eyes and waited. A flash made her screw her eyes tightly shut. The light was so bright it hurt her eyes. Slowly she opened her stinging eyes and saw a boy wearing goggles looking at her. "Are you all right?" he asked. She only managed "Yes, but..." before she fainted.

She woke up in a gray walled room, the walls were once originally white but lack of cleaning had soon seen to that. There was screen was a one end of the room with a large comfortable sofa in front of it and a table behind the sofa which had matching bar stools neatly tucked underneath. On her side of the room, there was a series of partitions, with a mattress in each. The partitions had silvery curtains that could be pulled across to hide the occupant within. She looked around, accumulating herself to her new surroundings. She now noticed a set of stairs leading up and a work bench that ran along the west wall perpendicular to the screen. The workbench appeared to have a basic kitchen at the end closest the table and a science lab all the rest of it.

"Oh! So you are still alive." came a voice from the stairs. Astrea spun round to see another teenager about her age, possibly a bit older standing there holding a gun. She was also wearing goggles, Astrea noticed. "Can you talk?" the voice asked. "Oh yeah um..." Astrea mumbled back.
