Ultraviolet by Nancy Bush

This is the third book in a series which I did not realize when I picked it up.  It isn't bad as a stand alone, but there is some background information that I would like to know.  This was a female detective story where Jane Kelly gets herself into some interesting spots.  The two investigations dealt with a murder of the father of the bride and a teen party get together that was up to no good.  This was not overly exciting and at times I really felt it was a trudge getting through.  I am curious of some of the back story though, so I may seek out the first couple of books to  see where this all started.
