When Grandfather comes to take his nonverbal grandson to a concert, Ronan is quiet as they leave the house, quiet in the car, and quiet at the concert hall. But when the performance is over and the beautiful music fades out at last, Ronan opens his mouth…and lets out a great big WOW! Not any old WOW, but Ronan’s very first WOW! That one word fills up the hearts of Ronan’s family, the musicians, the audience, and—when the recording goes viral—the world. Inspired by a true story.
