Chiral Mad volume 4 is open for submissions, and the key is collaboration:
Unlike past Written Backwards projects, this fourth volume in the critically-acclaimed series of anthologies will be a completely collaborative effort of originality, collecting 4 short stories, 4 novelettes, 4 novellas, and 4 graphic adaptations (to celebrate this 4th book), all co-authored and/or co-created. And the anthology itself will also be co-edited! The goal of Chiral Mad 4 is to help bring our creative community together, to make us stronger, to strengthen relationships already in place, and to help create new relationships entirely. It’s time for all of us to play nice, to get along, and to do what we do best: create somethings out of nothings… and we’re going to create these beautiful somethings together.
They are paying pro rates of 6 US cents per word, up to 20,000 words, split evenly between contributors. There is also one slot spare for graphic illustration work (up to about 10 pages) but you will need to query them directly first.
