“A Siren Song for Two” by Steven Fischer, Flash Fiction Online, October 2017, science fiction short story
This is the first of two recommendations from the odd (and oddly effective) Valloween issue of Flash Fiction Online in which darkness and relationships are combined.
Some workers are off on a planet of ice where the melting and refreezing of the ice causes a vibratory effect like a siren song which causes people to wander off and die in the unforgiving climate. When a woman succumbs to the lure, her beloved goes out after her.
This works on a metaphorical level more than a literal one but it evokes a vivid environment with effective emotional desires – the sonic singing iceworld is striking and the feelings that the woman has for the sounds, and that the protagonist has for the woman, are plausible enough and powerful. I honestly can’t decide whether to recommend this or just give it an honorable mention and I usually err on the side of strictness but I just feel like pointing this one out.
