Summary: Darker Matter, 2007
Darker Matter was a UK based e-zine that came in went in 2007. But it managed 5 issues before closing -- a pretty impressive total. There were 24 stories , all short, 7 short-shorts, about 70,000 words of fiction. The editor was Ben Coppin.
The fiction was uneven, as to be expected, really, but there was some good stuff, and the site was improving noticeably at the end. In particular, issue 5 included strong stories by Jason Stoddard ("True History", about manipulation of history and identity by posthumans), and Will McIntosh piece ("Young Love on the Drowned Side of the City", about an teenaged boy growing to some sort of maturity in a world where plague has wiped out most of the adults.) Earlier issues had good stories from David D. Levine ("Babel Probe", a retelling of the Tower of Babel with aliens), Bud Sparhawk ("Frost", SF/Horror (and sort of a Christmas story, too) about a scientists dark experiments as part of a colonization program), and Toiya Kristen Finley ("Dearest Etruria", about a shy man who falls for a beautiful woman, then loses her, only to find her again ... sort of). There was also interesting work from Eugie Foster, Daniel Braum, Jerry Oltion, and Lou Antonelli.
3.5 of 24 stories were by women (just under 15%). The 'zine was intended to be all SF, and I think every story did qualify as SF.
