I have tried out the Horrid Henry books with groups of children as a parent, as a babysitter, and as a teacher. Children love to either hear them read aloud, or to read them themselves. The books are spot on for the 5-8 age range, and are fun for the adults who share them too. You can read the Horrid Henry books in any order; they will all prove a smash hit. Funny and clever: they will appeal to children who like, or will go on to like Roald Dahl (although the humour isn't quite as rude as Dahl can be!)
