The Mouse With the Question Mark Tail by Richard Peck
Mouse Minor doesn’t really have a name, but is called Mouse Minor at school. He’d really like a name, but his guardian, Aunt Marigold, hasn’t given him one. She always says, “Nameless is blameless”, and won’t say anymore on the matter, or on most matters about him really, including where he came from and who his parents were. Being one of the smallest mice in school, he is often picked on and the hazing one day finally leads to him running away from school, a terrible thing to do. As if that weren’t bad enough, he then allows himself to be seen, clothed, by one of the princesses. After such a major mistake, Mouse Minor can’t go home, so instead he sets off to make inquiries of the Queen, because he believes that she can help him figure out who he is. After all, the queen knows all. This is a mostly a sweet story, but also has quite a bit of adventure in it. Kids who like animal adventure stories will probably like it.
