Years after her involvement in the Empire's war against fanatical Kanzi offshoots, Captain Morgan Casmir has volunteered for service at the far edge of A'Tol territory. Partly this is due to some romantic tension with her lovers, but mainly her involvement in taking down a precursor bio-artifact during the late war has brought her to fleet command's attention given that there is some evidence the artifact was not a one-off.
Now one of the Empire's precursor survey expeditions has gone missing and the people who made that happen may have an artifact that eats stars..
I enjoyed this outing in Stewart's "Duchy Of Terra" series. It was a nice change from the all-out space battles of the previous sub-trilogy, without lacking for large scale menace. I think Stewart's writing is getting a bit less ostentatiously woke, which is nice though Casmir did pick up another addition to her polyamorous grouping here. (And he is a welcome contrast: A "soft" non-military man, though he will do what has to be done when needed). I would have liked to see some speculation about negotiating with a certain class of new adversaries.
