It happened quite suddenly, The Change that gave all animals the power to speak, read, and understand human language. For Cheddar Plainmouse and the rest of his colony, The Change opens up an amazing world filled with new information and adventures inside the Crittertown Post Office, where the mice live. But when they learn that the post office is scheduled to be shut down, it's up to Cheddar and his two friends, Grayson and Nilla, to find a new home for the colony. Now, the trio must venture far beyond the safe and cozy dirt floors of the post office basement and explore the big world--a world filled with zooming cars, pouncing cats, hungry foxes, and lots of humans! Along the way, they meet a clan of super mean mice at the store next door, and some very smart mice at the local library.
