This is a well written book by two very renowned physicists. I enjoyed the book very much because it made me think about some very complex issues in regards to the meaning of our existence. It is certainly not easy reading but also not the most complex in this type of genre. That being said, it is easy enough to get through with a bit of effort and rewarding in that it gives you some very valuable information to ponder. Over all I would give this book a positive recommendation if you're interested in the topic.
