Its just a mess but in a very boring uninspired way. The best thing I can say about the book is that it tries to discuss some interesting topics, its just that the author doesn't seem to have any coherent position or real understanding of any of them.
The first section of the book is all about colonialism and violently "uplifting" people against their will. Despite the amount of pages dedicated to the topic, there really isn't any deep discussion and it is unceremoniously dropped about a third into the book.
Several PoV characters, mostly "good" guys, commit war crimes. They are aware what they are doing is war crimes but, as we are repeatedly told, they will either not be caught in the act or even if they are, no one will care to punish them. This somehow makes committing war crimes acceptable? It really felt like after being brought up dozens of times between several different instances, it would amount to something but it doesn't.
We have six major PoV characters. They include men and women, career military, politicians and spies and even two separate kinds of aliens. Despite that no one in this book has a distinctive PoV. Until I read the name of the character, I honestly could never tell whose eyes I was looking through. Even though we are told probably close to a hundred times over the book that aliens are impossible to understand, the two alien PoVs we have are actually trivially easy to understand.
We are never shown anyone doing anything, just told in the vaguest possible terms about how they've done something. An admiral spends weeks planning a battle which we never see and it all amounts to a conversation where he orders his people to "carry out plan Alpha 3" which appears to be everyone going at the enemy at the same time in a disorganized jumble. A politician spends months being overwhelmed by competing priorities and campaign promises but we never hear what a single one is and never see a single person being upset about their issue not being addressed. A marine officer spends some indeterminate amount of time (I think weeks?) fighting off an alien ground invasion by leading a resistance made up of civilians and we never actually see an engagement. We follow a spy around on a series of intelligence gathering missions but all scenes are either the spy traveling to or coming back from a dangerous location, never actually being there and risking something by gathering intel.
The writing is just horrendous. The same cliched expressions are used over and over again to the point where they become beyond meaningless. "... will pay a price at the next elections" (never happens), "... but they are aliens, you can't understand their motivations" (have multiple alien PoV that are indistinguishable from humans and trivial to understand), "Its illegal/against Interstellar conventions" (yet you do it over and over with no consequence), etc. Its repetitive to the point where any random sentence in the book is more likely to appear several times than be unique.
In short, poorly written, lacks imagination, has no exciting action or tension or mystery, characters are beyond bland, worldbuilding is very subpar. Wouldn't recommend it to anyone.
