An interesting story about rogue nanobots, Saturn and genetically engineered humans. Set in a space faring world still confined to the solar system, it was nice to see some hard SF eschewing interstellar travel. You can download it free from Smashwords.
“Loss Leader” by Simon Haynes
A story which originally appeared in an early edition of ASIM (which makes me feel like I should’ve read it before, but apparently I missed that issue). What happens when a company spends piles of money on a spaceship filled with cryogenically frozen settlers that the settlers aren’t keen on boarding? You treat the mission as a loss leader, of course. A bleakly amusing tale. You can download it free from Smashwords.
This is a slightly dark and sinister story set on a space station with a large Indonesian population. In the background there is war, in the foreground minor rebellion. A well drawn world and a great read. You can download it for free from Smashwords.
“Fed” by Mira Grant
This isn’t strictly speaking a short story but an alternate ending to Mira Grant’s novel Feed. It’s how things would have played out if one event near the end had happened differently. If you’ve read Feed you can probably guess which event. It’s understandably a little rougher than the finished novel (and somewhat lacking in characterisation where points of view have changed from the original), but still harrowing. You can read or download it (PDF link hidden at the bottom) on this Orbit page.
