I've held off on posting about this new market because 1) they had a failed Kickstarter and 2) the website wasn't up. Today I discovered that the site is up and the first set of stories is posted online. They're also available for purchase for your Kindles and other reading devices.
Now for the details. The Dark is a bi-monthly magazine looking for mainstream fiction with elements of the fantastic mixed in. Stories should be 1000 to 5000 words and payment is 5cents a word. You can find all the details here. If you click on the fiction tab at the top of the page you'll find their published fiction to get a feel for what they're looking for.
