I'm always thrilled when I come across quirky books like "The Transformation", which feel like they're much more than their genres, instead pushing boundaries. I was worried the synopsis, which drew me to the book in the first place, would end up being too similar to Suskind's "Perfume", though after finishing I can say that it was quite misleading, and similar only in the most general of ways.
The novel's charm and perfection lies in the way it balances setting and general world-building with the plot focusing on our three protagonists - the wig maker Lucien Goulet, the widow Marion Unger, and the young Cuban Rafael Mendez. Chidgey clearly put much work into the research component of the book, for it shows in the way the characters organically interact with their environment. As with Morgenstern's "The Night Circus", I do believe that "The Transformation" will find its audience in those who enjoy being instantly immersed in the writing as soon as they pick up the book, for I found it easy to get lost in the novel every time I picked it up. It's not the typical action-driven novel, which I greatly appreciated. The focus is much more on atmosphere and the careful weaving of the craft, which is echoed by M. Goulet himself on numerous occasions throughout the book, when he declares that a true master makes even the simplest things appear masterful. I enjoyed loathing Goulet's character, who is nonetheless brilliantly written in all his egoistical pomp and occasional idiotic logic. The same was with all other characters, for even the minor players were still fleshed out through the lens of Goulet. To feel a connection to Marion, to respond emotionally to her relationship with Rafael, and to feel angered by the protagonist, all at the same time, is a true success. (I also could not get the image of Stanley Tucci as Goulet out of my mind, and the image has forever solidified in my mind now.)
I would, however, warn future readers that "The Transformation" does include racial slurs, misogyny, sexism, and numerous very conservative and outdated modes of thought, some of which I struggled with myself while reading. It's best to approach this novel as a product of the time period it is trying to portray, hence all of the aforementioned aspects should probably be considered more as examples of what the past was filled with as opposed to the author encouraging such a mindset. Most readers might not have issues with it, but I think it's best to put that warning and thought out there for readers who might think of taking things found in books as signs of encouragement and promotion rather than as indirect criticisms or even the sad details of an all too real historical past, necessary for painting a more realistic picture. It was also sadly familiar how some of the things are still found in society today.
