It's a dreadful shock for Horrid Henry when Perfect Peter is born, and despite his best - or worst - efforts, he can't manage to get rid of him.

As Peter gets bigger, Henry gets crosser. But the day comes when Henry inadvertently finds himself saving Peter from a big fierce dog, and discovers that it's rather nice to be a hero.

Setting the scene for the Horrid Henry storybooks, this is a story with a universally recognizable theme.

The text is very simple and very funny and Kevin McAleenan's artwork is full of the spirit of a younger Horrid Henry.
