You’ve seen the posts every other week, so you know the deal. Write
something (poetry, flash fiction, whatever) under 1500 words based on
the prompt (see below). Post it at https://obsidianflash.com/forum
(click the forum button and register; it should be mostly painless).
That means that your work hasn’t been “previously published”.
The deadline is midnight tomorrow (2/17/2018), and critiques 24 hours after that.
You can see the prompt at https://imgur.com/a/sb8cG . Fair warning: it’s definitely aimed at horror writers and might be disturbing. (Though I would be delighted if someone did something other than horror with it!)
