Skyward Inn

First off, I have to give this book props on account of it being set in my home county of Devon (even if it is spit North Devon). The story and setting have clear antecedents in classic SF. The post technological rural lifestyle is reminiscent of the sort of thing that happens in the home stretch of John Wyndham novels, and it has other British doom guys like John Christopher and Richard Cowper in its DNA. Probably the biggest single influence is Ursula LeGuin, whose fingerprints are all over the human / alien contact and coexistence posited here.
It's no retro exercise though - it's quite easy to read it as a Brexit parable, and the final quarter goes on and outwards into deeply strange territory that recalls Jeff Vandermeer and a certain cult classic horror movie. Neither is it just the sum of the influences cited - Whiteley has her own ideas, and expresses them in some lovely prose, as well as crafting characters whose relationships, frustrations and temptations all ring true. It's quiet, thoughtful and very very good.
