I have read the whole series and this wasn't my favorite. I liked this book but did not love it. The cast of characters remain the same but they had "bit parts". The characters along with Kate made the books so good. I did not like the ending. The book was about secrets and what they can do to people.
There is a serial sexual predator among the Amish. The book does keep you guessing about who is the culprit of the crime of murder. The why becomes clear early on.
While this is a series you could read this book without reading the others. My recommendation is to read the early books first. They were really great! Hope Mona, Tomasetti, Pickles, Glock and Skid have larger parts in the books to come. Even the mayor did not have a part in this book.
