I'll be honest up front that romantic suspense is not my preferred genre, but I'm trying to be as objective as I can with this review. I enjoy regular suspense, though, so I am familiar with suspense techniques.
With some series, each book is a stand-alone and, while you might miss a few references here and there, you'll follow what's said without a problem. I don't think that's true with this one. There are many passing references at the beginning of this book to people and events from the previous two so if the reader hasn't read both of them, they'll feel a bit lost. (I know because I started with this book, but felt I was missing a lot so I ended up reading the others before I came back to this one.) If the reader has read both of the first two books, then the beginning part of this book will make sense.
In my opinion, this is the weakest of the three books in this series in regards both to plot and to the love relationship. I think both of those elements were much stronger in book two than either of the others.
Overall with the series, the suspense and plot elements have peaks and valleys, but it seems more valleys than peaks. There are moments of tension/fear, just not nearly enough to maintain an underlying sense of suspense. With the gravity of the crime (murder) among such a sheltered community, it seems there would be more concern by the characters for their well-being.
With this book in particular, it was a little too obvious that the author had a message she wanted to drive home, and it didn't seem to grow organically from the character or plot. Yes, it coordinated with it, but it took me as a reader out of the story.
The ending was not at all a surprise to me, but I guess it might be to some readers. It had more impact than the ending from the first book, but not as much as the second book. As someone who is used to non-romantic suspense, the plot was a bit contrived.
As for the relationship aspect of this one, the conflict between the two romantic characters didn't seem great enough to propel the storyline. Callie comes across as immature and a bit petty.
So, would I recommend this book? It depends on what you want out of a book. If you're the kind of reader who is totally focused on the relationship between the two romantic characters and plot doesn't matter, you'll find this a good (not great) read. If you need a logical, interesting plot, you might want to check out a different book.
Oh, and I just have to say, are there massive, violent snowstorms all the time in Kansas? From these books, apparently so.
