Set deep in the countryside in Twizell Village lives a timid, goodhearted country mouse. She is happiest in the countryside and lives in a delightful, cosy little cottage. This little mouse will do anything to help anyone in need! She has many experiences, such as venturing out of her village to travel to the big bustling town for the first time to look after her poorly friend, the town mouse, where she is challenged to come out of her comfort zone. Also, we read about her first time on an aeroplane, losing her first tooth, helping deliver mail over the busy Christmas period, and many more adventures.
