When Izzy Winkle - The Most Grateful Girl in the World - enters a competition to find The Most Ungrateful Girl in the World, she is plunged into a hidden society of secret agents, brave pigeons and warring manners. Daphne du Bois, Etiquette Queen of the Southern Hemisphere, says children should be seen and not heard. Horace Unthank, Professor of Appalling Behaviour, says children should roll in mud, helter-skelter down hills, chew furiously, spit words while chewing furiously ... With the help of her best friend Katie Skittle, Izzy must beat the Top Ten Ungrateful Girls. And save the world from fibs, nits and rudeness.
