Ghostwoods Books has two open calls here for some upcoming anthos:
Antho #1: Cthulhu Lies Dreaming
Looking for: "Lovecraft-styled cosmic horror with a modern sensibility, by which we mean without the lengthy passages of exposition and racial biases that were common in Lovecraft's day. This anthology has the working title of Cthulhu Lies Dreaming. The overarching theme will have to do with the way in which Cthulhu's dreams interact with the real world, either in the past or in the modern day. What horrors would Cthulhu dream of? If the substance of Cthulhu's dreams were made manifest in the world, what might happen? Stories do not have to mention Cthulhu or his dreams. To get an idea of what kinds of stories we might be looking for, a quick read of the back cover text of Cthulhu Lives! could be useful. Creativity will be rewarded as long as the story fits the general theme. Stories should be enjoyable for both those who have read Lovecraft's own work in depth, as well as those who haven't. As in Cthulhu Lives!, our goal is to reflect upon how deeply Lovecraft's themes remain embedded in the human psyche." Length: 3-8K; Payment: "Pays a small advance + an author share per story of 50% of the proceeds from the book." See guidelines for more details. Deadline: "When we get enough good stories. (We're shooting for May, but we'll put something firmer up when we're close to having enough.)"
Antho#2: Haunted Futures
Looking for: "The most suitable genres will be variations or combinations of sci fi, fantasy, thriller or mystery. We are not trying to scare the audience as with traditional horror. Haunted here is used more in the Romantic sense. Stories must be both excellent and suitable for an audience that enjoys the work of the notable authors who are to be included in the book. Outside of these primary concerns, we would also like to see more submissions from women and people underrepresented in traditional genre publishing." Length: 2.5-5K; Payment: "Advance plus royalties. Exact amount depends on the number of stories we accept." No reprints, see guidelines for more details. Deadline: "Early Summer 2015. When we get enough acceptable stories (we'll post a firm deadline as we get close)"
