I adored Six of Crows. Kaz is fantastic, I love every inch of his backstory. He's morally grey and likable.
Another aspect I enjoyed was the banter between Matthias and Nina, and everything involving Jesper. Inej and Wylan were also great, the world building, character development, just perfect.
This is probably one of my all time favorite books, I highly recommend it to anyone on the fence about it.
