Mouse by name, mouse by nature. Mouse is not prepared for her last-minute stay at Aunt Evie's. How will she cope at a new school without her parents around? But before Mouse has even unpacked her suitcase, she makes a new friend - a wombat called Miss Pearl! Suddenly, being in a strange cottage doesn't seem so bad, especially when she can snuggle up with a wombat. Mouse soon learns that not everyone in the area loves wombats, including Aunt Evie's landlord, a sheep farmer who destroys them on sight. Can Mouse find her voice in time to keep her furry friends safe?
