Five stars for writing quality and holding my interest. Three-and-a-half for reasons to follow. 
 What I liked: 
 - As mentioned, Knight's writing quality is outstanding. So is her editing; I found zero typos in Resistance, which isn't always the case even with conventionally-published books. 
 - The story moved along (for the most part), and managed to be very engaging without resort to non-stop action. 
 - The author wisely resisted the urge to utilize the main characters' "special powers" in this book. (I'm guessing they'll get more airtime later in the series.) This makes the said abilities seem more like facts of life and less like contrived superpowers. 
 - No magic - which will always be the case with any fantasy I read, but still worth noting. 
 - Gripping action scenes, relatable characters, and constructive principles - all the things that make a good, compelling story. 
 What I didn't like: 
 - A few plot elements were of the predictable/well-worn variety. For example: ((view spoiler)[Got a guy in the rebel band who hates another guy? Have the latter save the life of the former and they'll be friends in no time. (hide spoiler)]) 
 - The middle waxed a bit saggy for 10-15% of the book; there seemed to be a lot of moving characters into position without really having much for them to do in the interim. Ditto for the some of the descriptions, which were windier than I would have liked. 
 - God has another name (Elom), and is not revealed as Trinity in Resistance. While the accompanying general theological principles are sound, they're also pretty much limited to broad, Old Testament terms. Ilyon can't really have the Gospel, because it doesn't have Christ. 
 - There is some fairly intense violence. I'm going to give three examples, which are spoilers and graphic, so you were warned: 
 (view spoiler)[ 
 * Main character Kyrin kills a bad guy with an arrow to the throat, then observes him thrashing about making gurgling noises in his death throes as she and her friend Jace escape. 
 * Top bad guy Richard starts to amputate captive Kaden's finger with his dagger. (The idea, spelled out several times, is to cut Kaden up piece by piece and send the pieces to his sister Kyrin.) Richard doesn't finish the amputation, but he gets quite far with it. 
 * Also with Richard and Kaden, the former threatens to cut out the eye of the latter, with his sister watching, and goes so far as to press a dagger against his face for the purpose. Yeah, I know. Ugh. 
 (hide spoiler)] 
 The relatively graphic violence is the reason I'm not giving Resistance four stars, and most of the reason I'm not giving it five. I realize that, lacking a biblical standard on violence in fiction, people are going to have different views. I also realize that mine is quite far to one end of the spectrum. It is, however, my view - and in the end, that's what a book review is about. 
 I find it a shame to give a book like Resistance 3.5 stars, because it does so many things so very right. If not for the points I've mentioned, I would have rated this book among the best works of fiction ever.
