I've never read a book about synesthesia before. One of my psychology professors recommended this book in a cognition class a long, long time ago, and the concept sounded so fresh and exciting that the title of the book (which is a great title) stayed in my head rent-free all these years. I thrifted this book, which ended up being an additional joy, because my copy was annotated by the teen who read it before I did, and they were funny AF. I started keeping an eye out for their little notes in the margins because they were always on point. It felt like we were having a buddy-read.
Also, speaking of, I got to buddy-read this book with my friend, Ari!
Now that I've finished the book, I'm a little disappointed. I can tell the book did a lot of research into synesthesia, but I'm not sure how much of it is still true or relevant. For example, in this book, the heroine, Mia, can "see" other people's emotions and sense their pheromones as a color trail (why does that give me the ick). When I Googled this, the first thing that came up was the author's website, and the second was some kind of new age-looking website. I was immediately leery of this, because I feel like a lot of pseudoscience hypes up pheromones, and while it's been a while since my introductory neuroscience class, I remember my professor telling us that in most animals, chemoreception is done through the vomeronasal organ, which is considered a "vestigial" organ in humans (I seem to remember most people don't even have one).
Synesthesia in this book is also treated like a disability, with Mia's parents asking about cures and how it will affect her study. She gets bullied for it at at school and talks a lot about how it makes it difficult to function in certain situations from sensory overstimulation. I was looking through the reviews and it seems like synesthetes and neurodivergents took issue with this representation. (So did the little annotator of my book). This book came out in the aughts and a lot of these "single issue" YA and MG books were written like afterschool specials, not written so much for representation so much as to inform a normative audience (sometimes with unfortunate and now-dated stereotyping) that this reputation exists. When I think about some of the aughts era books with trans rep that I read, for example, it was always clear that the audience wasn't trans kids so much as cisgendered kids, because usually these stories were written from the perspective of a cisgendered kid who needed to learn that "trans kids, they're just like us." Synesthetes: when they're not stabbing themselves with acupuncture needles to experience a color high, they're just like us (oh yeah, THAT happened).
Also, this book is really sad. All the adults are mean helicopter parents who are like BUT SEEING COLORS WILL KEEP MY KID FROM GETTING INTO YALE, Mia's friends are pretty unsupportive, the cute boy with synesthesia that she meets only wants her for bad reasons (and she's THIRTEEN, ugh), and both animals in this book die in pretty traumatically descriptive scenes. I cried both times, for the dog and the cat. Two animal deaths feels excessive for a middle grade book that was supposed to be a fun journey about a kid who sees colors with words, numbers, and sounds.
2 to 2.5 out of 5 stars
