Theres nothing good about this book.
There are spelling, grammatical and syntax errors throughout. The are also random tense changes littered throughout. Most of the book is in past tense, but it slips into present or future for sentences at a time.
The book heavily relies on exposition. The author doesn't believe in the concept of show, don't tell. He explains every single minor detail at length. And then repeats the explanation several times. Pages and pages are wasted on nonsense. The characters will have a "conversation" where they are explaining something and then the author will break into the middle of it to further explain some details for a page or so and then go back into the "conversation" so the characters can finish explaining. It is almost unreadable. Almost all of the explanations and details are needless filler.
The author uses a particularly annoying trick where he throws fake encyclopedia entries into the middle of the text. It is very annoying and very poorly done. Luckily he forgets about that about a quarter of the way through.
Annoyingly, the author also forgets the backstory he creates with all the seemingly endless exposition. For instance, at the start they treat Earth as a forgotten home planet that people barely believe in. By the end, they talk about Earth measurements and Terran gravity.
What little story is allowed to exist amidst all the filler is dull and uninteresting. It relies heavily on tropes and cliche. There is no story arc or character arcs.
The characters are dull and bland to the extreme. Its made even worse due to the exposition because whenever they have a conversation the author ruins it with filler. For instance, when he writes them telling a joke he will stop the conversation to explain the joke. He does this even if the joke is obvious or has been told before in the story. The characters are given no driving motivators and their flaws are dealt with in minutes.
I'm pretty sure the author found a free rpg galaxy map generator online and based his stories on the free suggestions he got from that. There is a map he puts in occasionally that looks exactly like one I have seen online with the symbol key changed. It would explain why his stories are so cookie cutter and bland.
The author talks about being technically sound and mentions this being for fans of hard sci-fi, but there is nothing technical in the entire book and this is as soft as sci-fi gets.
In short - this author does not know the first thing about writing. His book is painfully bad and difficult to get through. I would highly advise not bothering with it. I regret spending the time to read it.
