To my mind, it’s a quite good example of a science fiction. The beginning was intriguing, the suspense interested me until the first long and detailed scientific description. I realize that the book was written in the epoch when a lot of described things were impossible…It was a little bit boring. But at the same time, the descriptions of underwater landscapes are beautiful and amazing.
The adventures of the main characters are written masterfully. I enjoyed the fantastic details, like navigation under Suez Canal.
I would advise to read this book, it’s interesting and informative.
