Writing Contest Entry (Time Travel theme)

I am going to apologise in advance for how weird and dark and creepy it is. I have a strange writing style. I am also going through phase where my writing always seems to include airplanes and death ??_(???)_/??

He swung his legs backwards and forwards over the edge of the cliff.

The sickly yellow-green ball of flames was dropping down below the craggy silhouetted mountains in the distance. Blood red sky enveloped that dying star as it made another weak descent below those ancient peaks.

It should have been beautiful.??

It wasn't.

It was just another reminder of the ten long years he had spent in this far, far future.

He had been taken from the airport cafe exactly ten years ago. He had spilt the coffee that had been held in his right hand as the man grabbed his arm and pulled him away from the warm shop, the bright lights, the delicious smell of coffee, and safety.

The evil man had dragged him onto the plane with the cosy yet unfamiliar interior.

The poor boy had been too busy screaming and crying and fighting to notice his time flying away as the plane set off.

And here he was. Ditched by the man at the end of the world. The sun was on the verge of dying, and the sky had polluted so badly in the years between the boy's old time and now that it had become the thick dark red of blood.

What remained of the humans were left to hide away in their makeshift homes, terrified of what would happen if they breathed in the Carbon Dioxide filled air.

The boy was not afraid of the deadly air however, it was quite the contrary. He no longer cared whether or not the gasses that swirled around him and filled his lungs were dangerous, he wanted to breathe it all in.

Yes, the boy was trying to commit suicide. Suicide in it's most awful way.

But who could blame him? He had been kidnapped from his parents and his time, then thrown to the end of the world and been abandoned to live alone in these unfamiliar conditions. He'd had ten years of that. It was only fair that he wanted the end.

That was one of the main reasons he was out here now, sat on the cliff edge and staring down at the crusty dry dirt below.??

Each time he swung his feet he would let his body slide a little further towards the edge and closer to certain death.

He wasn't scared; This was what he wanted. In fact, his mouth was open wide in a large grin as he thought of the prospect of the wind whipping his outgrown hair against his face, and the sweet pain as his legs snapped against the hard floor, and his whole lifeless body crumpled over.

In his ten years here, he had definitely become slightly insane, and in these last few moments his insanity was undoubtedly taking over his mind.

Before he could even decide life in this hell on Earth was worth living, he was falling.

The wide grin never left his face as his body soared down, rapid winds slapping his dark hair to his face, insane whoops of pleasure being ripped from his lungs.

Then came the beautiful pain as the loud snap of his bones seemed to echo out across the valleys of dry dirt where the sea once lay.

Little Theo was going to see his parents.
