My new Victorian fungus zombie short story should be up on Amazon shortly. I wrote the original version a couple of years ago for a print anthology, as an attempt to create a hard SF zombie story. It ended up less hard SF than zombie, so it didn’t get into the anthology, but I’ve since rewritten it to be about three times as long and cleared up the problems readers reported.
It’s discounted to $0.99 for Halloween, so, if you want a copy, get it while it’s cheap.
Should be at Amazon shortly.
