Query: Original Idea

To start off I am NOT a fan of vampire, horror, occult or the like. I am a fan of crime mystery set in the southwest. This book is a truly original idea in that genre. If you don't know why skinwalkers are evil or why German vampire is important to the story, that is because you assume the book is another type that you may find more interesting. For me I really liked the book. Combined with Ella Clah and Sister Agatha Aimée and David Thurlo are really pushing the envelope in this genre. Remeber it is NOT a vampire book, it is a criminal procedural set in the Dinetah.
