In The Shadows I'm Gone
There are days in my office that feel like this. I have checked behind the photocopier but all I found was a black, dried up banana peel and enough dust bunnies to start a ranch.
Very competent writing, the main character was very believable but it's another one of those No Ending stories.
I don't know if it's just my own perception but I have been seeing more and more of these recently (Daily Science Fiction, I'm looking at you) and they irritate the loving heck out of me.
I could be wrong, this could be the start of a novel or longer story, but quite often I just think the author ran out of ideas or couldn't find a way to finish the story arc. This is probably my own prejudice showing as for every ten story ideas I come up with I only seem to come up with a satisfactory end to one of them.
