The Mouse with the Question Mark Tail by Richard Peck
My rating: 3 of 5 stars
Perfectly competent animal-historical fiction, with more emphasis on the animal and less on the history.
Our hero is at times "Nameless", "Runt" or "Mouse Minor", a small mouse of unknown parentage raised in the Royal Mews at Buckingham Palace. He has an ordinary mouse life, albeit one filled with beatings by larger mice (in part because while small of stature, he's large of mouth). One day it gets to be too much and he runs away and there the fun begins. He's seen by a Princess of the Realm, is befriended by a Peg, a horse, becomes a Yeomouse of the Guard and kidnapped (mousenapped?) by bats. And that's only part of the two day trek from "Nameless" to... no, I won't spoil this.
More of the history (of the Palace, or the era, which is Victorian) would have been nice but the target audience won't miss any of that.
