Are you ready to meet the world’s worst children? Five beastly boys and five gruesome girls!

Like Sofia Sofa, a TV superfan so stuck to the sofa that she’s turning into one! And Blubbering Bertha, a bawling big sister with a horrid habit of telling tales!

From number one bestselling author David Walliams comes this collection of deliciously mischievous tales, illustrated throughout by artistic genius Tony Ross.
