Thousand Bones by P.J. Parish

Part of the Louis Kincaid series.

Focuses on Jo Frye, his partner and lover, as she tells him about her rookie year. Told in flashback, Frye recounts her investigation of serial murders 13 years earlier, in 1975. Frye's uneventful rookie year in the Leelanau County, Mich., sheriff's department undergoes a drastic change with the discovery of human bones in the woods of Echo Bay. Soon, the discovery of more bones and a multitude of artifacts point police to the conclusion that the remains belong to more than one victim. Mysterious Native American glyphs carved into a tree nearby provide the lead Frye needs to push herself to the front and puts others at risk.

I have not read any of the previous books but was intrigued by the storyline. This was a page turner but I found it hard to finish the book. I don't mind mysteries that give us the point of view of the murder which this story does really well until about midway through the book and they actually name him! It just spoiled it for me as I kept wanting to yell out "he's the killer! don't go with him!" but what can you do but read to the end. I have to say the ending was really 2 endings as we end the flashback and the end of the story. The end of the flashback was really powerful but since I have not read the other books in the series the ending of the story didn't really move me.

Interesting note is that the author is actually 2 sisters,Kristy Montee and Kelly Nichols, who write together.
