Read my story Pluto here. And be sure to check out the rest of The Moon Cake, aka the second edition of Lightning Cake. A Tumblr-based magazine of illustrated flash fiction, they have lots of pretty and whimsical stories.
Several of my personal favorites:
My Mars Base by Trevor Shikaze.
In addition to tiny speculative stories, Lightning Cake has art! This issue’s stories were illustrated by Scotland-based artist Jen Muir.
