Wind on the Moon

WINNER OF THE CARNEGIE MEDAL
Major Palfrey is leaving for the wars, and he tells his two girls, Dinah and Dorinda, to be good while he is gone. But the sisters aren't sure they can be. As Dorinda explains, "When we think we are behaving well, some grown-up person says we are really quite bad. It's difficult to tell which is which."
Sure enough, the sisters are soon up to their usual mischief. They convince a judge that minds must be changed as often as socks, stage an escape from the local zoo (thanks to a witch's potion which turns them into kangaroos), and--in the company of a golden puma and silver falcon--set off to rescue their father from the wicked tyrant of Bombardy. Penned at the height of World War II, this tale of hilarity and great adventure is also a work of high seriousness; after all, "life without freedom," as the valiant puma makes clear, "is a poor, poor thing."
