I bought this book to get into light novels (this is the first Dengeki book I read), and I was very surprised by how entertaining it was. When I chose this book, I thought it would be some kind of love story, and I was delighted when I realised that it was in fact a very nice mystery.
This being said, the story is very predictable and the mystery extremely easy to crack (in my opinion). At around one third of the book I was able to predict how the story would unfold and what would happen. Apart from some details and minor twists that I had not foreseen, the story did not have much to offer that I hadn’t already guessed. It felt like reading a detective book for children at times.
However, this did not prevent me from enjoying the story. Even if I think that the book could have challenged the reader a little more, following the protagonist in his adventure was extremely enjoyable and the story engrossing. I liked the characters and the settings, I liked the mechanism behind the story and overall, had a very pleasant time reading this book.
If you want to read a light novel with an interesting plot mechanism and a whodunnit flavour, this book is perfect. If you want to read a murder mystery that challenges you to find the culprit, you will certainly find 『アンフィニシュトの書』 too easy. Finally, if you are looking for easy books, I found this one quite easy to read. There is a repetitive pattern too, which makes it easier and easier to read as you get used to the vocabulary, characters and places.
Overall, this book was perfect to me because it was a mix of things that I love in novels: crime, mystery and books. If the author decides to makes a series around this theme, I will definitely be there for the other titles!
