Wemberly the mouse worries about a lot of things: What if her parents disappear in the middle of the night? What if she shrinks from taking a bath? What if she spills grape juice on her favorite stuffed animal? What if that noise coming from the radiator is really a snake? However, all these worries seem insignificant when Wemberly faces a very big worry: What will happen on the first day of school? Color illustrations accompany the story which gently deals with Wemberly`s fears. Named one of the Best Children`s Books 2000 by Publishers Weekly.
