As usual, the first Author's Publish of the month is their list of calls for submissions. It's a mixed bag including Nordic Horror, False Memories, Cats (the animal, not the musical), Time Travel horror comics, found fiction (think epistolary or similar fiction where the story purports to be an actual document), and much more.
