I am sorry to say that this book was practically unreadable. Structurally, thematically and grammatically, it is an absolute mess. Normally I would give examples of the issues I mention, but in this case they are so numerous my review would be nearly as long as his book, and I came close enough to that anyway.
The author chooses to write in present tense, which can be a challenge. However, he is horribly inconsistent with his tenses, switching to past tense quite often, even within a sentence. Another thing is that he has a large problem with homonyms. This is a common problem in self-published works, but he has a bigger problem than most. Then he has an issue with singular versus plural agreement between nouns and verbs; it makes reading an awkward experience. Also he seems to ignore the rules of possessives at random. Spelling is one area where he seems to be about average, though it is still a medium-level challenge. Then there are the dropped or missing words in a sentence, which tend to make the reader stop and back up in order to try to understand what seemed to be the point being made.
Finally, as part of the author's writing style, he uses sentence fragments with abandon. As an occasional writing tool, it can be effective in portraying immediacy and seriousness. The problem is that the author uses the concept in almost every paragraph, and quite often more than once in a paragraph. The upshot of all these issues, along with several more I have just forgotten to mention, it is a battle for the reader to move on with the story and still be able to make sense out of what it seems the author is trying to say.
As to his writing style, for this book it seems to break into two parts. For about the first third of the book, He jumps between time periods quite often. Now, some of them are titled as such, and I can understand his reasons for using it an expository method for the backstory. However, there are many other scenes where there is just a section marker, followed by something completely different. Two characters might be talking about where or when they should travel, and then after the section marker, they are in the midst of a battle with unknown adversaries where there had been no lead-up to it at all. For some reason, this seems to be a favorite style choice for him in the first part. As the book goes on, though, things seem to even out, and the reader does not get metaphorical whiplash from quick, unexplained scene changes.
For the story itself, because of all the challenges I have mentioned, it was difficult to get much from the story arc. Katryce whined about the cybernetics that were forced upon her to the point of annoyance. Yes, we get that she was not happy about being forced into having them. We don't need another soliloquy on it. Then there is Whisper, one of the AIs. We get that she does not like humans, but she only has two basic insults, and they get very old far before the book ends. The joke is funny a couple of times, but several horses gave their lives being beaten to death by the repetition.
In reading about the author, he seems so sincere in wanting to be a writer. Because of my review and general displeasure with this story, I decided to at least read a sample of his book "The Zero Class". I noticed from reading some reviews of that book, that others had similar issues to a similar extent with that book's contents that I do with "Whisper and Fury". The sample I read was from a major edit that the author did in answer to those concerns. While I still found all the issues I have mentioned, I noticed that there was a sincere attempt at improvement. At least for the sample, I was also able to follow and enjoy the story line; it was quite a bit more interesting.
I abhor giving out one-star reviews because a writer puts a lot of work into their product, and especially if the author is willing to try to learn and improve. Also, they are putting themselves out in the public arena with more guts than I have; I would love to write, but time and fear prevent me. Because of all that, and what I saw in his other book sample, I put "Whisper and Fury" at two stars, though with no interest in reading further in that series.
Good Luck, Mr. Powell. I hope you continue to learn and improve. You have a lot of room to grow.
