Ever since he can remember, Ralph the mouse has lived at the Mountain View Inn. But when the manager threatens to rid the place of mice, Ralph hops a ride to elementary school with his friend Ryan, the son of the hotel's housekeeper.

Once at school, Ralph becomes the center of attention after Ryan introduces him to the class as "Ralph S. Mouse." The S, according to Ryan, stands for Smart; but when friendly teacher Miss Kuckenbacker decides Ralph should be made to run a maze, Ralph gets scared. What if he can't get through the maze? What if he's not actually smart after all?

Bestselling children's book author Beverly Cleary brings readers a mouse in a million. His classic adventures now sport charming new illustrations by Jacqueline Rogers.
