This is in part prompted by a friend’s listing of SF/F featuring siblings and the attendant potential for ick. I tried to think of siblings done well in SF/F where…
1. Both sibs are alive and kickin’. Unfortunately, this means Jo Walton’s Among Others, featuring twins Morganna and Morwenna, does not count, because one of these two is dead before novel’s start, and so the focus is more on the survivor’s guilt and grief, not on sibling dynamics.
2. Incest isn’t a major thing; so no Cyteen, no GoT Lannisters, etc., etc.
3. At least one of the siblings is female; I think general fiction is filled with ambivalent brotherly fraternal dynamics.
I have to confess I’m drawing a blank! Part of me is thinking of Arya and Sansa from GoT but the series isn’t really “about” them as sisters. There’s Morgaine and Arthur from Mists of Avalon, but incest. The only one I can think of is Melpomene and her bro from Orbital Resonance, and really that novel took the healthiness of their bond and the exceptional nature of their relationship (because they were the only ones in their part of the station with siblings) as a given.
Any suggestions for others? Why are they your favorites?
