This must-have hardback has also been hailed as a masterpiece of criticism and invective. Over 400 new fragrances have been added to the original 1500 in this updated paperback. ''Perfumes: The Guide'' is the culmination of Turin's lifelong obsession and rare scientific flair and Sanchez's stylish and devoted blogging about every scent that she's ever loved and loathed. Together they make a fine and utterly persuasive argument for the unrecognized craft of perfume-making. Perfume writing has certainly never been this honest, compelling or downright entertaining.
