Having not read any of the Krewe of Hunters books before, I am happy to say I didn't feel like I was missing anything. There is enough of an introduction at the beginning to introduce who the Krewe are. I like the idea of an unit of law enforcement who have "certain" abilities.
Jane and Sloan rented a castle for their wedding. They find their minister dead at the bottom of the stairs. This was a nicely paced who done it. I am curious enough about the series that I might check it out.
