I wasn't feeling it for the first 70ish pages, but by the end of this book I am so emotionally attached to Katsa, Po and Bitterblue. Katsa and Po have the most tender relationship ever and it's so cute especially since Katsa acts like a feral raccoon with rabies. 

I really liked that this was a fantasy novel without "magic", everyones grace is an enhancement of their abilities or it's a perception/understanding of the world around them...it was cool.
