#21 River Marked by Patricia Briggs

 Mercy's surprise wedding starts out the book and is rather amusing. The honeymoon on the other hand is not all fun and romance. Turns out the lending of a RV and camping site by the Fey come with strings attached and has Mercy looking into a series of murders along the river.  The other factor in the solving of the murders is Mercy finding out about her father. A good read and I'll be looking for the next one.
