This review assumes you have read The Name of the Wind.
The story continues and is at the core more of the same what you got in the first book. We do see a bit more of the world this time, which is a good thing.
This book has only two problems really, and both of them minor.
The first is that Kvothe, who was already tiptoeing with regard to being a Mary Sue, has just moved even closer to that edge. True, it's never blatant in the way a typical Mary Sue's are and the setbacks he suffers are real enough. It's not so much that he himself is so amazing, it's that his environment aligns to him on occasion.
The effect is barely noticeable though, so if this sort of thing doesn't bother you, you won't be bothered here.
The second problem is that it doesn't really advance the main plot line. We get a whiff of it still being there, but that's it. A more substantial reveal would have helped to keep the epic story thread alive, which has all but petered out now.
If you loved the first you will love this one.
