3 stars from me. It was going to get 4 stars but there were some things that changed my mind in the end. 
 But first the good things. I usually like the stories about outcasts or thieves so I was having fun. It started great. Interesting story, lots of action, dark humor and well-written and interesting characters that I really liked. Especially Inej and Kaz. They are smart, they can fight and do a lot of cool things but they are also human and at times you can see that they are also vulnerable and their dark past certainly left a mark on them. The story took a few twists and turns that I didn't expect and there were times when I really didn't want to put the book down. It's really well-written. It has a lot of potential and it could be better but few things forced me to give it only 3 stars. 
 First of all, I stayed up late to finish the book. Waiting for the nice ending. I didn't even look at the pages. I got a cliffhanger. The book lost at least half a star for that. I usually do not react well to cliffhangers. Cheap trick and marketing tactic that I hate. Six of Crows doesn't have the worst of cliffhangers but I still don't like it. I feel like the author had enough pages to write a nice conclusion. Instead we got a lot of backstories of the characters. Interesting and in some cases heartbreaking but there were times when they interfered with the story and slowed it down. If you plan a sequel why put so many backstories in the first book but end up without a proper ending? And I'm not sure I like where the story is heading. 
 I also didn't like most of the parts with Nina and Matthias together. They love/hate relationship really annoyed me. Fortunately it changed in the end. 
 I don't really like the concept of being almost like a god. I do love cool superpowers but there are limits. I just didn't like what happened in the end and how they got away. Too easy. After all the hardships...it felt kind of stupid. And predictable the moment the Heartrender and army showed up. I wanted something else. 
 Oh and the last thing: we have Six of Crows and 3 pairs among them...I mean I do love great stories with love and friendship but it felt like it started to dominate the story at some point...and about Jesper and Wylan...my though was that the author has two complex heterosexual relationships so why not add one more and make it homosexual. Bit of everything for everybody I guess...I know there were only hints about Jesper and Wylan but they were clear enough. 
 I'm still going to read a sequel I think. Just not very soon. I feel kind of disappointed because for the good part of the book I thought I was going to give it 4 maybe even 5 stars.
