"A good read-aloud choice as summer approaches."—Booklist A sudden summer thunderstorm sends the squirrel siblings to seek shelter with new friends. A beloved book redesigned with a fresh new look. Mick, Mack, and Molly are enjoying a summer afternoon, when suddenly things are very still. Nothing is moving—not even the frogs, birds, or flowers. And then everyone is on the run—birds are flocking overhead and small animals are racing for shelter. Rain pours down and the thunder booms. Lightning cracks and flashes . . . and Mick, Mack, and Molly are caught in the middle of one of the most exciting moments of summer—a sudden summer thunderstorm. It can be scary, but for the three squirrel children, safe and dry in a cave, it brings new friends. Beloved author Kazuo Iwamura explores the seasons as he does in his other books—Hooray for Spring, Hooray for Fall, Hooray for Snow.
