"When a group of industrious, fun-loving rats find letters fallen from an Art Fair sign, they put the sign back together ... and get to work creating a spectacular RAT FAIR. Their fair is ruined when humans sweep away everything. Undaunted, the rats ... start working on their very own Rat Art Fair. As they are wrapping up their first day ... a human child who has been following their progress from the sidelines catches them red handed, and the rats must decide if they can trust the child"-- Provided by publishers.
