Query: This mystery sparkles

What a charming book! The author captures the appeal of the wine country (one of my favorite places) so well and it makes a great setting for a mystery. Nikki is appealing and believable in her quest to solve the crime. The suspects make quite interesting characters and I was left guessing up until the end. Can't wait to see what happens in the next book, especially between Nikki and Derek. I also enjoyed the recipes and wine pairings with the author's voice shining through.
