This picture book introduces younger children, probably in grade 3 or below, to synesthesia, in which one of the senses triggers a perception, usually color. The main character, Jillian, sees sounds as a color. A dog barking is red, and the sound of her classmates laughing at her when they learn of her special sense makes her see inky black. This is a wonderful story to begin discussions about how people perceive situations differently.
What made this book special for me is that the illustrator hears colors! I liked the illustrations the first time I read the story, but knowing that the illustrator provided a very real portrayal of synesthesia made it very unique.
