“Joel Salinas takes his reader into the harrowing, tender, and sometimes brutal realities of living with mirror-touch synesthesia. But the book’s reach is wider and deeper than the condition. It is nothing less than a reflection on human empathy itself, a book for everyone.” — Siri Hustvedt, author of What I Loved“Vicarious and enthralling…. A rich, fascinating portrait of extraordinary sensory awareness.” — Kirkus Reviews“He writes with depth and candor and immediacy, as well as a great deal of compassion in the Oliver Sacks tradition. I laughed, I cried… I found myself nodding in recognition. I predict this book will be a classic not only in the synesthesia literature, but in all of neuroscience.” — Psychology Today“A brilliant book that elegantly combines personal narrative with insights into the underlying science.” — V.S. Ramachandran, author of The Tell-Tale Brain and Phantoms in the Brain
