Björk, Dr Seuss, Whoopi Goldberg, Andy Warhol, Ellen MacArthur, Greta Gerwig, Andrea Bocelli, Hua Mulan - these are men and women who all dared to be different. Boys will be boys and girls will be girls - or so the meaningless saying goes. Because what if you're a girl and you like cage fighting? Or you're a boy and you love ballet? And what if you've always dreamed of being a scientist but you can't see anyone who looks or sounds like you, and who has left a legacy - in the form of microscopes and Bunsen burners - for you to follow? This is the book for children who want to know about the lives of those heroes who have led the way, changing the world for the better as they go.
