So far this is my least favorite book of the series. The writing is still great, the characters are good for the most part. I simply didn't like the content of this one, hence the low rating. 
 This book was longer than the others in the series and felt like it was dragging in places. It also felt like there was maybe one too many threats. 
 I was willing to forgive it when I thought the relationship sub plots would be resolved in this book. They weren't. 
 Personally I don't enjoy reading about girls trying to steal guys away from the heroine in books. It just bugs me. And so that played a big part of why I didn't like this one as much as the others. I picked it up despite knowing this would be a big portion of the book because I wanted to get to the next book in the series. Now I'm hesitant to get the one after because I don't want to go through another book where that's an issue (haven't read the blurb for book 5 yet).
