An old review from 2017:

Substrate Phantoms
by Jessica Reisman
The space station Termagenti—hub of commerce, culture, and civilization—may be haunted. Dangerous power surges, inexplicable energy manifestations, and strange accidents plague the station.
From the blurb
I am not sure what to make of this book. I liked it, unexpectedly, as it was off to a slow start. It was poetic in parts. Interesting ideas. A fascinating first contact story. It made me feel sad for long stretches. Confused in the beginning. Slow build-up, slow paced, with a twist at the ending that I saw coming, but that worked well.
The beginning was a little difficult to get into. I had to come to grips with the unusual vocabulary and odd grammar. It was a good way to impress the otherness of the setting to me. Hard SciFi, I guess. I liked Termagenti station, but even more so the setting down on Ash, with it’s landscapes, memorable characters and the amazement of the station-born characters at encountering nature.
I liked the idea of the other characters taking up residence inside of Jhinsei. I wish the author had played around with that more. Maybe the book had felt more solid for me, if the author had explored that more deeply. But even so, lots to think about. I am sure this book is going to stay with me for some time.
World building with a lot of potential. I think I would like to pick up a sequel, to find out where the story takes the central characters.
I received this free e-copy from the publisher/author via NetGalley, in exchange for an honest review, thank you!
