I won a copy of this on BookishFirst for review.
The summary and genre piqued my interest. Contemporary mixed with historical fiction? Check. A hidden library? Check check. Romance and mystery? Let's go!
The story was intriguing, though I plodded through early on. The reliance on God/prayer to provide a miracle to find lost treasure rubbed me the wrong way, as did having the plot rely on Grandma Joy's memory to help Millie and Ben solve the mystery. That said, it was overall a fun read and I enjoyed the dynamic between the two protagonists. I wish that more action had taken place on the Chateau - it was a very intriguing location.
I'd recommend to anyone that enjoys romance and/or a light read.
