As I've noted in my review of 
 A Court of Thorns and Roses 
 , it was really good, but it was also a bit weak. Thus I was a bit wary of how this book would go. But Maas did not disappoint. Whilst A Court of Thorns and Roses was really good, A Court of Mist and Fury is really, really good. I'm now convinced to keep reading this book series, and buy the books.
