Speculative-fiction magazine.
The primary limit that Abyss and Apex place on submissions is that they have a speculative component, emphasising that, beyond this, they are happy to consider such wide-ranging sub-genres as high fantasy, magic realism, hard science fiction, sword and sorcery, and 'genrebending stories that don't quite seem to fit elsewhere.' They do, however, have a blanket embargo on publishing horror, including material with graphic violence, graphic sexual content, 'over-the-top gore', or gratitutous swearing.
