This book wound up being just ok for me.
What I loved: the premise was there and it has serious potential. The scenery of Switzerland and setting of the story throughout Europe was well written. I love stories that take place in the past and that are well done. These can really make or break a story!
What I did not: The characters. I did not buy into the chemistry from these two and I did not find their relationship exciting. Since the whole plot pretty much banked off of their relationship, this needed to be much more exciting than it actually was.
I passed this book onto a friend after I read it and she was a big fan of the work! So I know it is not the actual story. It just was not the right story for me.
