Originally part of Samuel Peralta's 'Z Chronicles' anthology, the story follows Elie and Little Shrew, two disenfranchised American teenagers fleeing the apocalypse.
Clocking in at 6,000 words, 'Girl, Running' is available now for just 99p, or if you are part of the Kindle Unlimited programme, you can borrow it for free.
Little Shrew is still calculating in her mind – speed versus distance versus pain in joints – when Elie says, 'Okay, in five seconds, we're going to run for the Harbour building.'
'Elie, no. I'm in a lot of pain.'
'Sweetie, we can't wait, you know that, right? The soldiers aren't going to shoot because the sound will bring even more of these...people...over. There's not enough of them there to hold the place as it is. If the fence comes down, the military are going to close the doors and sail away.'
Little Shrew is incensed by Elie's steely calm observations. She's not sure whether the pain she is in is stopping her from thinking straight, or her inability to think is somehow contributing to the pain.
Elie slaps her on the back and practically pulls a salute. 'Time to shine, Little Shrew. This is where that time on the track is going to pay off.'
'Two more minutes,' Little Shrew pleads.
Elie vaults the wall in a single movement, graceful as a cat. One of the shamblers nearby is more alert than the others, and takes a three-iron to the temple for its trouble.
