Due to a backlog of submissions, Aeon Speculative Fiction is temporarily closed to submissions. Editors Marti and Bridget McKenna are now focused on catching up, and will re-open in the near future.
In the meantime, writers’ guidelines for the “quarterly electronic magazine of fiction and nonfiction of interest to readers of science fiction and fantasy” are available here.
Additionally, they expect issue #14 to be available any day.
