When lightning flares in the faraway sky and clouds growl like lions walking, big brother Chad is thrilled by the coming storm. But not little Brannon. He looks for a place to hide. Each adult tries to calm Brannon in turn by comparing thunder to something that's not scary. 'It's only a cat purring,' Daddy says. But Brannon has once been frightened by a cat-and again he runs to take cover. It's not until the thunder is compared to dinosaurs that Brannon loses his fear. He knows all about dinosaurs. He loves them and always wanted to see one. Now he finds himself comforting himself-and his big brother-as he Clomps and he Stomps and he Rages and Rumbles with all the ferocity of Dinosaur Thunder.
