First things first, some content warnings about the book: it contains a lot of violence, a narrator who uses ableist language and ideas repeatedly, and a sort of sensory-illusion body horror that I thought was one of the book's strong points but could be deeply disturbing for the wrong reader.

I want to like this book. It does a great job of imagining aliens who are very deeply alien and in unsettling ways. And at it's best it's a tautly narrated story of the terrifying encounter with them. It also plays some amusing games with vampire tropes, and poses interesting questions about what counts as life, sentience, intelligence, etc.

But I found some of the author's tics grating enough to really put me off. The voice is irritatingly macho-male, to the extent that it makes me, a cis man, want to yell at the author to shut up and cede the mic. In the first half there's a really clunky tendency to do foreshadowing very explicitly, which intensifies the macho storytelling feel. And the narrator is consistently casually ableist, even though there are aspects of the overall story and the narrator's life history which push back hard on the same.

I'm glad I read it, but not sure I can really recommend it.
