This unique collection of science fiction stories focuses on the human emotions that have no place in a world made unrecognizable by science and technology. Three stories that deal with the Kethani aliens—a group that has come to present-day Earth offering life after death via technological resurrection—are included, as is “The Children of Winter,” a lucid tale of doomed love between alien species on a far-off world in the distant future. As characters are pushed to their moral thresholds, they attempt to deal with the unforseen consequences contained in fascinating new technologies.
Two of Eric Brown's stories included in Threshold Shift won British Science Fiction awards: "Children of Winter" (2001) and "Hunting the Slarque" (1999). I can see why, as each has a creative setting, interesting themes, plot twists, and are dark in a way that seems to garner the automatic stamp of 'serious'. Others of his stories address what feels like a classic 'what-if' SF questions: what would happen if an alien race offered humans immortality in exchange for service? However, I don't think the stories are particularly well served by being gathered in this collection. The similarity in themes between stories creates a sameness that gets a bit boring, even with themes like suicide. Brown's characters felt like actors placed to embody certain ideas and to do certain actions, rather than like real, relate-able people. I'm forgiving of this in say, a intergalactic war story, but less so for stories as interested in psychology as these.
