I started this book and got about an hour into it and realized this was the same universe as the Grisha Trilogy. I did a little research to see if I needed to read the trilogy first and I got mixed reports. So I decided to put this book on hold and read the Grisha Trilogy first. Well, I can say for certain sure that I am glad I did that. The cameos that popped up in Six of Crows were very brief but I am glad I knew exactly who the people being referenced were. It gave it more weight and had a deeper effect. 
 After the Grisha Trilogy I wasn't sure what to expect from Six of Crows and Leigh Bardugo did not disappoint. I was really excited to see the Grisha universe from a totally different angle. Not only were we dealing with slum rats instead of soldiers or highly trained Grisha, but we were given the opportunity to experience a lot of the other cultures and countries that were only mentioned in the Grisha Trilogy. I liked that there were no love triangles, though I do like a well written love triangle, and I enjoyed seeing the story unfold from the perspectives of nearly everyone in the crew. It made it more diverse, more rich. As the book began to come to a close, I wasn't sure how Leigh Bardugo was going to fit another whole book into this line up but I was worrying for nothing. The ending was one I honestly didn't expect and I am eager to listen to the next book and see where she takes us. 
 The recording of this book was BRILLIANT! Each chapter was written from a different character's third person limited perspective and the producers of the audiobook took that and ran with it. They decided to have a different narrator take on each different character and only narrate when it was from their perspective! It was different than what I am used to but it worked like a charm! 
 Lauren Fortgang was brought back (She narrated the Grisha Trilogy) and I was delighted. She is a fantastic narrator and did an amazing job as Inej. Her voice changes for the different characters are so well crafted and she really puts a lot of emotion into her work. 
 David Ledoux as Kaz did a good job though his voice is one that took me a bit to get used to. 
 Elizabeth Evans as Nina brought a wonderfully sassy and strong voice to her sections and also did a wonderful job with her voice changes. 
 Brandon Rubin as Jesper was a lot easier to get used to than David Ledoux (his voice wasn't quite as deep and raspy) though his one downfall was that the voice changes he did for the different characters were so slim at times it was harder to follow who was saying what and what was happening. Although with how he read I am almost tempted to forgive him this flaw, a flaw that earns a black spot for most narrators that embrace it. 
 Jay Snyder as Mathias also has a very deep voice but his was smooth and rumbling. It was the perfect voice for Mathias, the Fjerdan giant, and he did the voice differentiation best out of all the men in the main cast. 
 I can't have this review be full without mentioning the two actors who only got one chapter each, book-ending this wonderful ride. 
 Tristan Morris begins the book for us as Joost the sad little guard on a mercher's estate and he does a great job! I wish he had seen more of him and I think he is definitely a narrator to watch in future projects. 
 Last but not least we heard Roger Clark as Pekka. His accent was one that I had a hard time placing and it was quite detracting for the first couple of minutes because I had to really listen to understand all the words. Once I grasped the cadence of his voice and accent it was fine. However, he didn't have to do voices for anyone but Pekka and Kaz and I am left wondering hoe good he would be narrating with a larger cast of voice changes.
