First, the Firefly fic, written for this year's
Spook_Me challenge (which I forgot to sign up for, blast it! Oh, well, September was busy...): "
Isolation" by
bluflamingo. Trips like this are enough to make Mal resolve never to take passengers again.
And second, the SGA fic: "
Wanderer," by
boochicken. Getting an explanation of earth customs can take some doing.
Gen fic, both PG or so, and spooky in different ways. Enjoy!
