I had some high expectations for this book since it is a prequel to one of my favorite books Code Name Verity. I wanted to see how Queenie got to the point that she could become a spy. There are a few of these elements but I still feel like that the two books just really stand on their own. That is by no means something bad but I would just have loved to see more connections.
This book taught me a lot about Scotland and the Highland Travellers which I am very happy with because I love books that can teach you something.
I think this book is great for mystery lovers who also love historical fiction.
