I just read about this and thought the book lovers here might like to know. Since you are book lovers, I think some of you will already know!
I'm about to delve into my 4th Ragnar Jonasson mystery. He is an Iceland author and the book is of course set in Iceland. Two of the books took place at Christmas time. No mention of the traditional book exchange. I'm wondering why not. He gives lots of history. Interesting what you posted.
