Hattie was bad. Really bad. When I say bad, I don't just mean forget-to-tidy-her-room, reading-comics-after-bedtime kind of bad. No, she was SO bad, no-one was allowed to play with her. But it's no fun being bad on your own, is it? So, she becomes Hattie the Good. Good Hattie tidies her room and goes to bed early. But nobody likes a goody-two shoes now, do they?! In the most hilarious moment in a picture book EVER, Hattie rebels in spectacular fashion and reverts to being bad . . . for good!
