Query: Excellent book

William Kent Krueger is one of my favorite authors and I was not disapointed in this book. It is however, a sequel to Mercy Falls (his previous) so I would recommend you read it first so you are aware of the history. They are both stand alone books though so it is an enjoyable read none the less. Good suspense with a double twist at the end.
