Horrid Henry & his friends put forward their most dastardly dares & side-splitting jokes to prove once & for all that boys rule. But little does Henry know that Moody Margaret has plans of her own resulting in a hilariously horrid showdown! Filled with witty comments & acerbic asides from Henry & Margarets friends enemies families & teachers along with brand new Tony Ross illustrations this book should keep Henrys (and Margarets!) fans mischievously quiet.
