Worms! (Dirty Bertie)

Alan MacDonald is a British children’s author best known for writing funny, fast-paced, and highly readable books for young readers, especially those in early and middle primary school. His work is designed to hook reluctant readers, not impress literary critics — and that’s exactly why it sells. He is most widely recognised for his hugely popular “Dirty Bertie” series, illustrated by David Roberts. The series became a staple in UK schools and libraries because it uses simple language, short chapters, strong humour, and mischievous characters — everything teachers and parents look for when trying to get kids to actually read.
