"The English Roses" is about a group of girls who are envious of another girl, Binah, and so they exclude her from their activities and parties. The girls eventually find out that Binah's life is not at all easy. They realise how lucky they are and eventually accept Binah into their circle.
This story, which targets older children, teaches them not to judge others, to look beyond appearances, and to appreciate what they already have. Bonus: It's illustrated beautifully, too.
