The world got a bit of an expansion and we got to know other places, and their situations.
This book suffered a bit of the second book syndrome, to me if felt like it dragged a bit more and that it was a lot of setup for the next book.
We get a lot more work on the relationships and therefore more time spent with the love interests. That leads to a few personal arguments and such that didn't always feel very well developed for me but it didn't detract from the story too much.
The mystery to solve in this book is a bit of the continuation from the previous book but felt less surprising.
Overall still a good book and I'll keep going but not as enthusiastically as the first.
