A New York Times Bestseller This creatively wacky exploration of the invisible things that make up the human experience encourages readers to look past the visible and connect with the things that are not seen. If we could put on a pair of magical invisible glasses and see all the feelings, ideas, and other invisible things that populate our world, what would they look like? Could you see an itch? Could you describe hope? From the sound of a dog barking to the rainbow-MAGIC taste of a lollipop, from gratitude to grit, this book will help you meet the many interesting sensations that follow you every day, even if you can't see them. Explore the way a sad song can sometimes make you happy and discover that laughs—even fake ones—can multiply faster than you'd imagine.
