I can't put into words how good this book was. I just... I loved it. The plot wasn't like anything I've ever read before, and kept me on the edge of my seat the whole time. There seemed to be a plot twist every chapter, with backstabbing and double crossing and scams that shocked me every time! I could barely keep track of what was truth and what was lies, or what was planned and what was pure improvisation. 
 The characters were, in one word, incredible. I loved the diversity of them all; where they came from, why they were taking part in this major heist, their backgrounds and what they were prepared to do for themselves and each other. The romance was done really well, it wasn't in your face but gave a deeper meaning to a lot of the characters and their actions. I think the place for favourite character goes to Inej, with Jesper a close second, but I did love them all. 
 There's only one criticism I have- the whole world building wasnt done well enough for me, and I often got confused about the different types of grisha and all the history that was briefly mentioned. This may be my fault though, as I haven't read the original grisha trilogy- I'm guessed everything's explained more there? Despite this, overall Six of Crows was definitely one of the best books I've ever read, and I'll be moving straight onto the sequel. There were sad moments, tense moments, touching moments, moments filled with jokes and banter and moments where I was left lost for words. Everyone should read this book!
