Here's an open call from SF Romance Quarterly for their upcoming tenth issue:
"THEME FOR ISSUE 10: No special theme…give it your best shot!
Length: 2,000 to 7,500 words.
Payment: 2.5 cents/word (US) paid upon publication, promotional biography with two links, and a complimentary quarter-page advertisement.
Deadline for Issue #9: 15 February 2015.
Rights sought: Six-month exclusive world digital rights from date of publication; non-exclusive thereafter.
Other info: One short story will be published per issue. Please send only edited and polished work. Due to time constraints, we are unable to give personalized feedback on rejected stories.
Stories that tie-in to a previously established world will be considered, but story must stand alone.
All sub-genres of science fiction will be considered.
Any heat level, from sweet to erotic, will be considered. Original, previously unpublished fiction only. No fan fiction, please.
Story should meld the Science Fiction and Romance genres, and must have an upbeat (HEA/HFN) ending. Not quite sure what we’re looking for? Read our original fiction in previous issues.
No multiple submissions. No stories that have previously been rejected by us. Simultaneous submissions are accepted, but please inform us if the story is placed elsewhere."
