Second paragraph of third chapter:

That’s not a word I often hear.

This won the Tiptree Award (now the Otherwise Award) in 2018. It’s a short book about a post-apocalypse future England, in a world where most human men have died of a gender-specific virus and the survivors live in secret reservations, while women get on with running civilisation. Our protagonist is a teenager who has no idea that men are still around; she meets a teenage boy who has fled his reservation, and finds out more about her society than she expected to. I see a lot of very unenthusiastic reviews of this book online, but I rather liked it; I think I can see what the author was trying to do. You can get it here.

The Tiptree Award shortlist included a short story, five novels and one duology. The only one I have read is An Excess Male, by Maggie Shen.

The BSFA Award that year was won by The Rift, by Nina Allan; the Clarke Award was won by Dreams Before the Start of Time, by Anne Charnock, which was also on the BSFA ballot. (I wrote both up here.) The Hugo and Nebula both went to The Stone Sky, by N.K. Jemisin.

The following year the Tiptree Award (as it still was) went to a short story, “They Will Dream in the Garden” by Gabriela Damián Miravete, so that will be next in this sequence.
