 There seem to be a lot of mixed feelings on this book with people either DNF'ing their ARCs or loving them, fortunately I was one of the people who LOVED it! I was very pleasantly surprised with how much I enjoyed "Mask of Shadows" everything about it was entertaining and it really blew away all of my expectations! 
 Trigger Warnings: Misgendering and Much Violence (gets pretty brutal at times) 
 Plot 
 As you can see in the descriptions right away this is being compared to books by both Sarah J. Maas and Leigh Bardugo but let me tell you I thought this book was so much better than those! You can see the similarities to the plot of this book and that of "Throne of Glass" right away, which I did, but trust me when I tell you I thought this was far better than "Throne of Glass". "Mask of Shadows" was essentially everything I had wanted "Throne of Glass" to actually be: full of action, brutal violence, and a main character who isn't all talk! So I personally thought the descriptions didn't do this book justice, or it did in case you're a big fan of either of those authors I suppose. 
 I really loved how we are tossed into some action immediately at the beginning of the story and we don't waste anytime getting into all the action the synopsis promised! Of course considering the fact that Sal is auditioning to become part of the Left Hand there is quite a bit of training in many various areas so those parts can become a bit tedious, I personally found them enjoyable though. I also liked how none of the contestants were messing around either, they were hardcore! I actually really liked how brutal and violent the lot of them were because this means the author wasn't sugar coating the fact that these people are trying out to be ASSASSINS. That's what they do. 
 While the pacing wasn't necessarily fast and went kind of back and forth a little bit, I still never got bored while reading since there was always something going on. The action definitely wasn't lacking here! But as I said the pacing did go back and forth pretty erratically. 
 The plot was very entertaining, even though it seems it could be a run of the mill YA fantasy plot. Sal's thirst for revenge and the lengths they go to achieve the revenge was interesting to read about and definitely had me rooting for them. 
 Another thing that was very well done was the world building but I could have used a little more of it as well. I thought one of the most interesting points were the "shadows" which I won't go into detail about but the descriptions honestly terrified me! I personally never felt like I was being "info dumped" on but I could see some people getting annoyed with the amount of info being spilled all at once throughout reading. 
 There were quite a few shocking plot twists and that ending definitely has me dying to read the sequel! 
 Characters 
 One of the best things about "Mask of Shadows" is the fact that the main character, Sal, is gender fluid, that's right we have a gender fluid main character in a YA fantasy! While I personally cannot say whether this was represented well or not I read a review from an amazing blogger I follow (Avery @ The Book Deviant) who has an own voices review up that I will link for you to check out! 
 It's stated in the book that Sal prefers to use the she/her pronouns when dressed as a woman, the he/his pronouns when dressed as a man, and they/their pronouns when dressed as neither. Since this is just a book review I will refer to Sal using the they/their pronouns. 
 Sal was a fantastic character and I really adored them, they just had so much spunk and spirit. However, they also came with their flaws as well from the rough past that they've had and what they're willing to do to get their revenge as well. I LOVED that Sal came into the competition with a realistic set of skills and admitted that they didn't know everything and did their best to learn other skills worthy of an assassin. That is so unbelievable refreshing, a main character that doesn't magically have ALL the skills! 
 I'd also like to take a moment here to discuss the cases of misgendering Sal that occurred in the book. This happens in one instance at the beginning of the story and Sal corrects them right away explaining how they liked to be addressed according to what they are wearing and it doesn't happen again. However, there is a more villainous character that misgenders Sal more than a few times and Sal challenges it immediately, which I loved. There is just one thing that goes along with this that I wanted to mention was that Sal states they like to be addressed as they dress: dresses for she/her and trousers/tunics/leggings for he/him. Now I KNOW this is just a fantasy and most clothing is gendered and that's accepted but when Sal is misgendered by what they are wearing they state that "clearly" they are a woman/man by how they are dressed and would get very angry (which is understandable of course). I just kind of didn't like this considering the fact that women and men can dress in whatever clothes they like and not have to identify as that gender based off of the clothes they are wearing, especially since this is a book about a diverse character. 
 Food for thought and hopefully that made some sort of sense. 
 AS for the secondary characters I really enjoyed quite a few of them but mostly I adored the other members of the Queen's Left Hand: Emerald, Amethyst, and Ruby (MOST OF ALL RUBY!). I didn't have too hard of a time keeping track of the other contestants but it did get a little annoying at times considering they were only ever referred to by number. Elise was also a pretty great character and I loved that she was diverse as well (either bisexual or pansexual) since she states that she's interested in more than just men. 
 There is a romance in this story but it doesn't take central stage and is more of a minor plot device. It really wasn't anything special though and was more of your run of the mill YA fantasy romance. 
 In Conclusion 
 Overall I really did have a great time reading this book and it surpassed ALL of my expectations! 
 What I Loved: 
 -Genderfluid and overall fantastic main character 
 -Stabby plot that doesn't sugarcoat! 
 -Interesting world building 
 -Great secondary characters (mostly Ruby...) 
 What I Didn't Love: 
 -Erratic pacing 
 -Sal's outlook (or just the book's) on gendered clothing 
 Recommend? 
 I highly recommend checking out this book whether you're looking for a fun new YA fantasy or if you're looking for a great diverse read as well!
