ReviewPRAISE FOR THE WORLD'S WORST CHILDREN: "This really is Walliams at his most indulgently gross and silly - the perfect combination for thousands of his loyal fans... stunningly illustrated by Ross who captures the energy and chaos of the stories." - Daily Mail "Laugh-out-loud funny and...downright disgusting" - Daily Express "Often described as the modern-day Roald Dahl, Walliams is a big author with big ideas and plenty of illustrations, all combining to make for real page-turners, even for kids who would normally look at you as if you're mad to suggest reading for pleasure." - The IndependentAbout the AuthorDavid Walliams has revolutionised reading for children and become one of the most influential children's writers today.
