Welcome to Horrid Henry's wicked world - the essential A-Z of all things hilarious and horrid, crazy and chaotic, fiendishly fantastic and utterly brilliant.

Horrid Henry can't believe his mean, horrible parents are forcing him to stay overnight at his slimy cousin Stuck-up Steve's house. And to make matters worse, Steve's house is haunted. Or is it?

Horrid Henry hates babysitters - and he knows exactly how to make sure they never come back. That is, until he meets Rabid Rebecca, the toughest teen in town.

How far away can you hear a lion roar? How do dolphins breathe underwater? Is it really true that elephants never forget? Bursting with weird facts and freaky trivia, this is the perfect guide to everything a Horrid Henry fan has ever wanted to know about animals. Gross out your parents, scare your little brother and amaze your friends with your new knowledge.

In these four new stories, Horrid Henry helps himself to all the money he needs to win his favourite board game, comes up with another spectacular money-making scheme for launching a newspaper with all the school gossip, vows vengeance on Perfect Peter when Peter nicks his birthday party theme and has his own pirate party.

This is a collection of four Horrid Henry tales - Horrid Henry and the abominable snowman, Horrid Henry's rainy day, Moody Margaret's makeover, and Horrid Henry's author visit.

Anything Moody Margaret can do, Horrid Henry can do better. So when Margaret starts giving her friends makeovers, Henry decides to steal - no, borrow! - her idea. He is sure he can do it much, much better. It can't be that hard to make people look really fantastic, can it?

Henry is up to his horrid tricks again. He tries, and fails, to trick the tooth fairy, rids his family of an unwelcome houseguest and single-handedly creates havoc at Cousin Polly's wedding.

This is a new collection of four stories about this favourite character - one of the few new characters to have emerged in recent years for this age group.
