This book is incredibly interesting and readable despite the difficulty of the topic on the boundaries of physics and philosophy.
After the first chapters that cast the basis of the contemporary physics, the second half will blow your mind with all the anthropic principle-related theories.
The first half is in my opinion too deep into physics, meaning that it's too much for the understanding of the the second part and that having some previous knowledge of physics would certainly help.
Getting to the more philosophical section, all the theories are absolutely well explained and the mind twists trying to grab them. The author also includes his own opinion and, very useful, the final chapter recapitulates the main points of the book: everything can be rather confusing.
I suggest not to read it all at once in order to give time to digest the concepts and formulate personal ideas. There is no right or wrong theory, at least with the present knowledge of physics and universe. I had already read other books by Davies but this is by far the best, he is a great popularizer.
Any book that tries to discuss the universe, existence and life risks falling off a tightrope. Talk only about the scientific facts and some will say you're missing the big picture. Talk too much about the speculations and others will say you're philosophizing. Paul Davies has done a fine job walking this tightrope. He has nicely balanced his discussion on sound scientific theories and informed speculations.
