(I'm just going to review the whole book in this)
This was really good. Like really, really good. This was the flashback book for Shallan and I thought her flashbacks were better than Kaladin's from the first book and really fleshed out her backstory. The revelation at the end for her was crazy.
Kaladin's arc was also great in this, although obviously the focus was less on him than in the first book. A certain moment with him was amazing and we finally saw the importance of Syl and the spren. 
Dalinar had more of a backseat role in this but I know that Oathbringer is his flashback book so it makes sense. 
Obviously we got the traditional Sanderlanche in this which was just a rollercoaster ride and the moment with Adolin at the end was quite unexpected but satisfying.
The events at the end have major ramifications and I can't wait to get to Oathbringer. I'm still juggling if I like this or Way of Kings more but both are probably some of my favourite books of all time.
