I was born in Pisa and I couldn't wait to read a book set in my city. It was an interesting and fascinating reading, the author was very good at describing life in the 12th century that really seemed to be there. Both stories, the one set in the XII century and the one in the XX , are well built and the transition from one to another was very compelling making the reading even more engaging.
Sam's husband has a stroke while in Pisa to make a documentary. She reaches him and casually discovers the story of Berta, of her husband Lorenzo and architect Gerardo ....
It's really well written, it does not seem to be written by a debut author.
Highly recommended
