Orbannin Books is open to their first anthology, ‘Letters from the Grave’ and looking for submissions:
The epistolary form has a long, proud tradition in the horror genre. From the classics such as Frankenstein and Dracula, through modern classics like World War Z. We want to see your fresh takes on the idea. Remember that the epistolary genre doesn’t just include letters. It can be stories created from nearly any kinds or combinations of documents, i.e. crime scene reports, diary entries, interview transcripts, etc. This can include modern electronic and digital “documents” such as texts, voicemails, Tweets, blog posts, and more. Original stories only, no reprints.
They’re reading stories up to 10,000 words, and paying 5c USD/word and a paperback contributor copy. Deadline is 31st of March 2019, but they’re already sending out acceptances so get in quickly before it fills up.
