I remember seeing this book advertised on a Christian booksellers website around 2009 or so. I am fairly certain there was three (possibly more) books in the series.
It was a mystery with a female protagonist (I think her name was Cassie) who was married. She made perfumes for a living. I think she also went camping.
I think the series was published in the early 2000s. It could be earlier, but I doubt it.
The cover was fairly artistic. Black or grayish mostly with something in a colored silhouette. Maybe a flower?
