Since this is the fifth book in the series I'll make this simple. At this point you already know what to expect and you're already invested. 
 It has everything we come to love with the series. A continuation of a really epic and broad scale tale. Richly detailed medieval world to get lost in with plenty of lore. Some of the characters who we missed in the last book are back. Some of the characters have very interesting character growth which is the best part of the book. 
 It also has all the problems with the series. Lots of POV hopping, this time it feels like there are more minor characters and most are hard to feel attached to or interesting. While the scenes changes tend to stay in the same general area it still takes a while with each chapter to remember who is who and figure out what is happening. 
 I think this is the weakest of the series books. While it does have the trademark surprise moments it feels very much like it is setting up the pieces for the next book. At this point the story scope is so big picture it hard to feel invested half the time and feel like a history lesson. 
 If you read the other four books you're already invested and there are some significant plot points you'll need to know before the next book. Just be prepared for a long and slow story.
