Prologue

'Can we go outside?'
A small girl, around seven, gazed at her mother with startingly green eyes whilst tucking her long, chestnut hair underneath the dining table. She was in the middle of dinner, however, the food was left unfinished.
The woman on the other side of the table just raised an eyebrow.
'Done with your food?' She asked.
'Mhm.' The girl replied.
The older woman leaned back, allowing her short brown hair (resembling her daughter's) to settle on the chair.
'Table,' she called out, 'view camera from above please. Isolate point from a metre south of sound origin.'
Suddenly, a small square by suqare screen on the palm of the table shifted the screening on it to the small girl's dinner plate, showing that there were two small pieces of cauliflower laying around, and heavily spread ketchup with about four fries.
The woman sighed, but then let out a small smile.
She moved forward to her daughter.
'Alright, but get back before it's dark. And don't go near the edge.' She said in a barely audible whisper.
The young girl smirked and pushed out her chair, happily opening the garden door. But still at the dinner table was her older brother. The mother turned to him.
'Are you going to follow her?'
'Give her a second; she likes to get headstarts.' He responded.

Soon enough, the girl raced herself down the garden, letting the wind breeze through strands of her tangled hair. Her legs got the best of her and she wasn't moving by will anymore, altough she wasn't opposed to it either.
Then, she was followed by her older brother, who chased her until he was level with her. They kept running through the grass before the air started to get thinner. And thinner. And thinner.
'Wait, stop!' The girl exclaimed. The boy did as was told and bent down, trying to catch his breath. The smaller sibling sat onto the grass, and saw that it was dusk.
'Do you think we should go inside?' She asked, tilting her head.
'But we only just got out.' The boy said, sitting down too.
The girl fiddled with the grass in front of her, apparently very interested with intertwining them.
'It's getting dark. We aren't allowed to be outside when it's dark.' She muttered.
'Does it matter?' The brunette boy placed his chin on top of his two hands.
Looking up the girl smirked once again. Then abruptly, she stood up.
'Okay, we'll have about five minutes. Race you down the hill!' She started to run as fast as she could.
The boy smiled and stood. Knowing she likes headstarts, he gave her five seconds before speeding towards her. The air got more thinner. It was becoming intense. The girl's hair was flying in the air and her feet had once again took off. But it wasn't long before in the corner of her eye, a figure was running much faster than she was. As soon as he crossed her, he turned and was skipping backwards, facing his sister.
'I won again.' He said smugly. They were both striding now, and he turned back to the grass ahead of him.
'That's not fair, you always win.' The girl furrowed her eyebrows.
The boy swiftly turned back to her, and opened his mouth to say something. But whatever it was he was going to say, the girl never got to hear, because his right foot had stepped onto nothingness, leaving him to fall through a gap that separated the children and the rest of the world. He hadn't made any sound; it seemes he hadn't realised that he was falling to his death.
There was silence for a second. Then, panic began. The girl screamed and looked over the edge to her brother's falling body. Still in shock, she fell to her knees, careful not to fall, and screamed again. Soon, her brother's body would come flying right back up, but down again, because there was a gap through the middle of the earth. The gravitational field would force his body to repeat this hellish epiphany until it rot. The girl yelled his name many times, Owen, not expecting anything back. She layed back onto the ground, trying to force a reaction out of her. He was probably already dead from the air pressure. It was the end for him, and the girl couldn't do anything. She wouldn't. Instead, she lay there, processing through what had just happened in the last two minutes.
