Pearl's Promise — Frank Asch

Pearl will never forget the day her mother and father were sold. Ever since, Pearl, a white mouse living in Mr. Adams' Pet Store, has taken charge of her younger brother, Tony. All's well until Prang, an evil-tempered snake, arrives in the pet store – and Mr. Adams targets Tony for Prang's next meal. To make matters worse, Pearl herself is sold the next day, but she vows to return to save Tony. How is she ever going to get back? And if she does, can she match wits with the vicious Prang? Humorous illustrations add to the fun in this charming and irresistible story of faith and courage.
