Query: Very Disappointed

I have read the entire series of Dr. Kay Scarpetta and would always get so excited when a new book came out in the series. However, this is the first time I was strongly disappointed in one of the books. I felt Cornwell was all over the place with her characters, which made it difficult to become involved with any of the characters with any depth. Each chapter went from one character to another but never deep enough to feel connected or interested in any of the characters. In fact, there was less about Dr. Scarpetta in this book and she has always been the main character. This was a true disappointment for me.
