The Big Tidy-Up, by Norah Smaridge
originally published in 1970, recently re-published by Random House.
Meet Jennifer. A girl who lived in a room which was a disgrace...."A very old, worn-put lollipop was stuck to her bathrobe pocket. And her bureau drawer, it was plain to see, had been struck by a super rocket..." until one day at last opened her window wide and worked and worked for most of the day....Perfect for Spring Cleaning!
