 Trigger Warnings: Graphic description of injuries, medical procedures, and health issues. 
 I really don't know how to rate this book because while it was still interesting I'm left feeling a little disappointed with it. I also just had some very personal issues with some of the content (which I will go into detail about below) so I'm left giving it a rating of 2.5 because I neither strongly liked or strongly disliked this book. 
 I'd like to first go out on a limb and say this book really, really wasn't what I was expecting at all. I was expecting something with a little more suspense and thriller style twists to it, but what I got was a pretty predictable plot line and a very unlikable main character. There is a bit of a twist half way through and the story takes a turn but it wasn't very shocking and I really disliked the second half of the story because it was super slow. 
 The pacing was pretty even throughout the beginning of the book and I kept reading wanting to know more about Sasha's situation but as I mentioned previously there's a twist half way through that made the story take a bit of a dive as far as pacing goes. I thought it was considerably slower and even pretty boring all the way through to the end. 
 There's hardly any plot twists which was really disappointing for a mystery/thriller and the big plot twist that makes up the entire story is very predictable and not at all a surprise. Also disappointing. I was expecting there to be a lot more shockers than that. PLUS a lot of stuff is given away in the synopsis! I hate that! 
 I do really like unreliable narrators and in this case the story was pretty good since Sasha is a very unreliable narrator. She actually makes the story very dark as her character flaws come to the light and we don't know what to believe. That's part of why I enjoyed the story and was able to finish it. 
 However, as much as I love an unreliable narrator and a dark plot the book actually got really, really......weird. Usually I love weird but with this I just felt super confused and I finished the book thinking "What the hell did I just read?" and not really in a good way. I enjoy a good open ended book but with this ending I felt like a bit more explanation or plot development would have done it a lot of good. The only comprehensible thought I have on the ending of this book is it's WEIRD. 
 The writing was really great though and I found it to be extremely readable, honestly it was probably one of the reasons I was able to read this through to the end. I will definitely be checking out McGinnis' other books just for more of her writing. 
 Last but not least I'd like to address one of my biggest issues with this book which also happens to be a personal issue of mine. This may or may not affect your reading of this book but I'd like to throw it out there and that has to do with the trigger warning I listed at the start of this review: 
 I have anxiety and a big part of my anxiety is linked to my health (i.e. hypochondria) and therefore I cannot stand reading about or listening to in depth descriptions of health issues or medical procedures because it triggers my anxiety. "This Darkness Mine" really goes into great description of these things and it becomes a major part of the plot, if I had known this ahead of time I probably wouldn't have wanted to read the book since reading through this triggered my anxiety to the point where I had to stop reading at times. This is a big part of why I didn't rate this book higher, it's a personal issue I understand but one I wanted to warn others about as well. 
 The characters in this book are another drawback for me, while I liked that Sasha (the MC) was an unreliable narrator making the story a bit more interesting, she was extremely unlikable. We're talking a downright crappy person and it was frustrating to read through and listen to her say rude things to and about people. I understand that these things were Sasha's character flaws and were there to drive a point home about her and none of these things were portrayed in a positive way. However, this didn't make me enjoy her any more. 
 There were actually quite a few side characters that I liked such as Sasha's friend Brooke and Isaac who is the love interest. I thought Brooke was hilarious and her bits were worth reading and Isaac was actually such a sweetheart and I feel terrible about some of the things that happen to him. 
 While I really liked Isaac and I wanted him to be happy I just felt that Sasha treated him like crap, plain and simple. It definitely isn't a healthy or positive relationship but McGinnis doesn't glorify this at all which I liked. Neither Isaac nor Sasha are physically or verbally abusive to one another but I just feel like it's still unhealthy because of the way Sasha negatively treats him at times. 
 As I said there are a lot of mixed feelings on this book because while some things worked a lot of them didn't for me. 
 What I Loved: 
 Unreliable narrator, dark atmosphere 
 Writing 
 Side Characters 
 What I Didn't Love: 
 Slow pacing in second half 
 Predictable 
 Plot is given away in synopsis 
 Weird....just downright weird plot 
 Unexplained, confusing ending 
 Trigger Warning Material 
 Unlikable main character 
 Negative romance 
 I'd recommend reading this only if you like unreliable/unlikable main characters, strange plots with open endings, and if you aren't triggered by anything I mentioned in the warnings. Otherwise I'd steer clear of this one.
