Crisis in Crittertown — Justine Fontes

It happened quite suddenly...The Change that gave all animals the power to speak 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.

Venturing beyond the cozy post office basement, the trio meets mice at the store and at the library. They also encounter a wide world filled with zooming cars, pouncing cats, hungry foxes, and lots of humans! Danger threatens at every turn in this race against time, but with their newfound gift of gab these little mice are up for the challenge!
