Ralph S. Mouse

In this third and final Ralph S. Mouse novel from Newbery Medal–winning author Beverly Cleary, Ralph heads to school to see what humans do all day . . . and to discover what the “S” in Ralph S. Mouse stands for!
With his rowdy cousins constantly wearing out his motorcycle and the Mountain View Inn manager threatening to take care of the mouse infestation once and for all, Ralph decides it’s time to get away for a while. He convinces his human friend Ryan to take him along to school, where Ralph becomes an instant hit.
But Ralph doesn’t like being told what to do, and his motorcycle gets broken. What if he’s not as clever as he thought?
