Fall or Fly

The sky blazed above the cradle of death. The city, once a haven, was now a place of ghosts and broken promises. Posters fluttered in the clammy breeze, still shouting their promises to the apocalyptic wasteland.
"Ammy!"
Footsteps toddled over the rubble, followed by two skinny little girls. Their laughter ricocheting  off the scorched walls.
"Daisy look! A house like what we used to have!"
"Wha? Ammy wait for me".
The elder sibling melted from the shattered doorway into the cavernous black within. They were before the age when rational fear begins to blur the seams of reality. Soot danced in the air currents kicked up by their little feet.
"Oof"
"Daisy?!"
"Ammy I fell..."
Before Amelia could tend to her fallen sibling a stray beam of dying sunlight electrocuted the stairway. Held by the spectral sight, the girls paced slowly towards the steps.
At the top of the steps a small ladder leading vertically to a small hatch swung. It screeched it long, drawn out phrases.
"Ammy, le's go"
"...Ok...lets"
Amelia pulled hard on the cord handle; the hatch was soldered shut after a year neglect, dust and ash.
POOF
A cloud of grey danced around the children making them choke and smother.  They took tentative steps forwards, and were greeted by and endless sky, flecked with diamonds. A flock of pigeons rustled and cooed in the burnt alcoves.
"Ammy, le's be pigeons!"
The two sisters flapped and squawked, forgetting the burnt out waste they fought everyday to survive in.
Then Ammy, the eldest, wobbled over to the precipice of the building.
"Daisy, watch me fly! I'm just like a pigeon, and I'll fly up to see Mummy and Daddy. Just watch"
"Ammy? AMMY NO"
It was fall or fly.
A child tumbled through the smoggy air against a backdrop of black velvet spangled with silver blood.
