I've been reading for decades and there are only an handful of books that I can say I was sorry to come to the end of. This was one of them.
It ticked most of the boxes that I am looking for in SF. I love a lived-in universe and stories about people just trying to make a living I find particularly compelling.
The Wayfarer is a tunnelling ship that builds shortcuts in space/time. This sounds very sci-fi, but in this book, it's just a way of life, a job and it is not that glamorous. To paraphrase something from the story, "History remembers who fought the wars and signed the treaties but nobody remembers who built the roads."
I would have been content just to read about how hard it was to construct these tunnels, or to live on the ship and to keep it maintained. But the author gave so much more. Reading about the varied crew members and where they came from was equally fascinating.
There was a terrific amount of world building here but none of it felt forced or ever got boring.
Chambers has created a massive world, well, a galaxy actually that I look forward to visiting again and again.
