If you’re still hungry for genre fiction short stories that you can read online, you could do far worse than click on over to Subterranean Press, who have just updated their online magazine with new content from two big names: a super-short riff on the demotion of Pluto from planet status by hard-touring John Scalzi, and a new story from hot property Joe Hill (yes, that Joe Hill, son of Stephen King) that ties in with his bestselling novel Heart-Shaped Box.
