Horrid Henry is the very first book in the entire series, originally published in 1994. This groundbreaking collection of four stories introduced the world to the outrageously naughty protagonist, Horrid Henry, and his perfectly angelic younger brother, Perfect Peter. The book establishes the central dynamic of the series: Henry's constant struggle against the rules, his imaginative ways of being horrid, and the long-suffering reaction of his parents and teachers. The original stories include classic scenarios where Henry tries to avoid eating vegetables or ruins a family trip, all presented with Francesca Simon's sharp, funny writing and Tony Ross's iconic illustrations. This book is the essential starting point that defined Henry as the ultimate childhood anti-hero, setting the standard for all subsequent chaos.
