I found this book by chance because, frankly, this is the title that push me to read it. I'm not disappointed in this little book that reveals the secret that each of us bears never consider it. The style is pleasant and reality, if believed, is not without giving some hope that we would all need at this time when we all lose our bearings. I recommend it to those who want to get an idea about these things have a way of staying in the shade while tormenting us to the spot.
