I love stories surrounded by mysteries and puzzles. When I opened the book I got a scare though. There was a time-line and a character list in the front of the book. As this gave me the feeling the story would be hard to follow I reluctantly started to read. I soon found out though that the time line and list are just little notes for the story if you need it to hold on too. The characters are not to many and the relationships between the various main characters are clear. The story builds up very fast with the 8 people Emil has to gather on certain positions. It is a nice set up and you start to guess with every person he is meeting if that person belongs to his group and if yes what the spot is. Not all where clear until the end and I liked the way the Octavo grows bigger and bigger and it gets clear what other people are involved.I loved the folding fan aspect of the story. I did see them regular on images from that period but never knew the history behind them and that they where used in the way as described in the book. I did some Google searches after reading and found a lot of extra information and nice facts.The story is told from different perspectives. If Emil is the one writing down his story he is using I but he is also writing down the stories that where told. Usually I am easily distracted when this is used in a book but the changing points of view where carefully separated in chapters making it clear for the reader immediately that the point of view would change and it was fluent.If you are scared of the puzzle books like the Rose Labyrinth or Angels and Demons you can actually pick up this book. It is not as heavy or complicated as those. The tone is lighter and the puzzle feeling can be ignored without losing touch with the rest of the story.
