Bottom line Up Front: Misleading description; contrived and unrealistic scenarios and action scenes; and a cop that refuses to pull the trigger. Key Characters often spontaneously behave unrealistically, and sometimes contrary to their initial characterization, just to further the ever increasingly contrived plot. There's a lot of unrealized potential here.
The book's description ended with these statements:
"In a chase across Taurus Station, Deputy Walker must prove he's fit to wear the badge and issue his own form of justice...one body at a time. Experience this exciting beginning to a brand new series set in the Renegade Star universe. If you're a fan of Judge Dredd, Renegade Star, or Borderlands, you'll love this epic, scifi thriller."
That passage is paints a very specific picture and makes very specific promises... which it then utterly fails to deliver upon. Almost the entire time, the MC refuses to pull the trigger on bad guys -- even when it's not just justified, but necessary and recommended. I think he kills maybe 2 or three people in this entire book, and that is mainly after his partner has gotten shot to near-death with live ammunition.
If you thought this was going to be Die-Hard in space, or even Borderlands or Judge Dredd (as the author claims), you are going to be sorely disappointed. There are probably well over a dozen different scenarios where lethal force would have been legitimately justified, and yet the MC doesn't aim or fire fire his weapon, and often doesn't even draw his sidearm.
---very minor spoilers that don't really spoil much because no names are said and no larger context is given---
Let me paint you a picture of how idiotically and unrealistically unwilling to shoot people this guy is. His new partner/training officer is disarmed, and captured in a room with a gang boss and his thugs, who are all beating the shit out of said partner. His suit has a flashbang function that basically blinds everyone else in the room for a good solid minute or two. His AI advisor/legal assistant says that lethal force is authorized.
So what does he do when he flashes the entire room and everyone but him is completely debilitated for an extended period of time? Does he shoot all of the thugs beating up his partner and arrest the gang boss? No. He drags his partner away and closes the door behind him. Then has a chat with his partner. Then when the thugs finally starts recovering, he leads them on a merry chase into a room full of civilians in the middle of a wedding ceremony for a huge knock down, drag out brawl.
You see what I mean about contrived scenarios? All of that drama and "action" at the wedding ceremony could have been avoided if he had just shot everyone in the room and cuffed the boss instead of dragging his wounded partner away. And don't even get me started on how atrocious the wedding ceremony brawl was, since everyone had guns, but no one shot anyone else and people were apparently handing out and drinking booze at the bar as they were fighting. Heck, the gang boss's entire reason for being there made no sense, given how they conducted themselves once engaged with the civilians.

And this type of thing is endemic throughout the entire story. This leads to a compounding problem that snowballs upon itself. In essence, his failure to act realistically (and the fact that he seems to have kid gloves surgically grafted to his hands) results in an over-the-top and contrived action scene, scenario, or chain of events. Events that could have easily been ended before it even started, or handled in a much better way. It knocks you completely out of your suspension of disbelief and takes you out of the story. Worse yet, his unrealistic reaction to that contrived scenario, then leads to more unrealistic and contrived scenarios, that he then reacts unrealistically to. It's a mess.
If you wanted John Wick: Cop Edition; Borderlands as a Sherriff's deputy; or Judge Dredd on a Space Station, this is NOT IT.
