It's one of those days in the city when the sidewalk is hot as a frying pan, and Mimi and her little brother Joe are sweatin' out rivers. Spyin' on Mama and the blah blah ladies is no fun. Out on the street the buses are huffin' out dragon-hot smoke. Even a princess-pink snow cone melts away too fast to lick. Then Mimi and Joe find their way to a place where it's always cool, a place where you can be a princess on a throne or a dinosaur in a forest, a place where you can let your imagination run free . . . the library. Gregory Christie's red-hot illustrations team up with Barbara Joosse's smooth urban voice in this book that points the way to the coolest place in any city.
