Each PJ story is set in a new universe, but with many similarities between them. We never really out of place, in the right sense, one is immediately in the bath.
A galaxy (or more) conquered by men, more or less at war, the maternas (centers of "production" and education of humans), civilized planets and borders, wilder, in the purest style Wild West .
In this story, Yoran, a promising young lieutenant of the space, is dismissed for a "minor" offense which would earn him a reprimand from. He then approached by the ETC, a company, a little opaque, specializing in the testing of new technologies, located in the confines.
Artificial intelligence, chase spaceship, conspiracy, treachery, small and sweet romance. All the ingredients for what the author promised in his preface, a nice space opera that will read only once, which will drown in the author's mass production, but which has done its job, good evening entertaining read.
For the downside: about 330 pages of the book, the story ends two-thirds, the end is not that filling. Readable certainly, but that takes nothing more. A format and word count to respect suppose?
