The topic is interesting. It lies where science meets science fiction. It is easy to understand also... But, probably the main problem with this book is the author's writing style. He repeats himself and can become boring at times. Also, there is no flow in the story. It kind of sounds more like bits and pieces put forcibly together. The information was there, it just didn't keep the curiosity up. One could put down the book after each section and not feel the need to go back to reading. A pity for such an interesting subject.
