What a great, great book. I just finished reading it and was heading for the computer to leave some good words on Amazon to praise this masterpiece. Being a perfumer's apprentice myself, I can judge the book from own experience working with most of the raw materials described and having had similar insights in the last few years.
Mr. Turin knows 100% what he is talking about. This is no "I copy from other books and hopefully nobody will notice" type of thing. The secret of scent is amazingly well written, it reads like a novell, like an adventure in science. Reading it means great fun. Luca writes in a way so you can understand and not so you just know how dumb you are and how smart the author thinks he is, as many other "science books" are composed. I would recommend it to just everybody being interested in how perfumes "tick", but for perfumers it is a "Nr. 1 must read".
The secret of scent starts with a description of why we can't make perfumes only with natural substances alone and how it came we went deeper and deeper in understanding scents using chemistry. It then explains very detailed and in a crystal clear logical chain HOW WE SMELL!
The secret of scent left me breathless; a true revelation in the science of scent. Since I gave only one star to Luca's other book "Perfumes - The Guide", I must say that I did not expect at all this book to be of such an outstanding quality. IMHO, this book has a place among the "100 best popular science books ever written".
