There were exciting and thrilled fight scenes between the main character and the enemies. I felt as if I was watching a film, and I often forgot that I was reading it in English which I am learning.
By the way, in the story, there were the really existed city name, area, and even an architect, so I enjoyed to read it while seeing a map. However, on the other hand, it had a lot of the words of Finnish proper nouns. I gave up listening the audio, and I decided it to read only the text.
