I haven't read the other books in this series so I can't comment on the hold-up of the setting. Usually with books I would never start out of order, but with some mystery cozies it can be allowable.
I don't think I suffered much missing by beginning with the third book here. Aggie is a cool person with a great personality to follow. Her inner humor is fun and she's not too flighty or obnoxiously risky. I guess this is another series where deaths, bodies, and mysteries keep falling into the heroine's lap. I haven't read a book from the point of view of a pastor's wife before so that was interesting to do. It was in no way religious themed or preachy or anything, so no need to be turned off by that.
At first the story was a bit dry and wasn't the easiest to get sucked into, but it slowly unfolded. This is the main reason is stays a three star. The mystery wasn't the biggest in the world but it was a fun enough ride if you have the book laying around on a rainy day. It was completely a cozy mystery and there was much cuteness to endear the reader. The sense of humor translated naturally across the page thanks to the writer's style and ease of wording.
Really the humor and heroine's personality reigns as the stories strongest point. The mystery was a little lackluster but the end was a bit of surprise with some of what it held. I would read another book in this series to see how much I'd want to continue it, but as of this reading it not a mystery series favorite yet.
