Iris is the only Deaf student in her class. Though sometimes frustrated, she reads lips though prefers to use American Sign Language (ASL). She’s also most comfortable when working with old radios and their components. When she learns about a unique whale, Blue 55, that is not part of a pod she becomes convinced that it, too, is deaf and thus separate from others. And unlikely but riveting adventure with her grandmother leads to healing and a satisfying conclusion.
