A human generation ship returns to a terraformed world where spiders have become the dominating intelligent species. It's a good book though sometimes a little predictable, especially the last two or three chapters.
Still a good read / listen. Not for people who are scared of spiders though 😂
The alternating viewpoints of the planet dwelling spiders and the human crew are also reflected by the use of present versus past tense.
I think there is a sequel involving octopuses...
Mel Hudson does a fine job as the narrator. No complaints there.
