It's not Kitty's fault when she's late for school and Dad crashed into the gatepost! It's not Kitty's fault that baby Tom crawls into trouble or that she's getting too old to sit on Dad's knee! And it's certainly not Kitty's fault that her boring cousin Melissa can't make friends at school! But for some reason Kitty feels that it is.

"It's not fair!" is Kitty's plaintive cry. Why is she the shortest in her class? Why can't anyone in her family take a joke? Why can't she go to bed as late as the boy next door? Why don't holidays last forever? When one day Kitty's mother echoes Kitty's cry of "It's not fair" Kitty thinks up a brilliant idea...

Kitty's favourite word is no! She doesn't want to clean her teeth, eat her vegetables or play with boring Melissa. She can't stop saying no, but when Dad tells her he doesn't want to hear her say yes, she discovers that's what she does want to say!

Kitty decides as she gets older that she knows certain things. The trouble is, grown-ups keep treating her like a baby and she is sick of it. So Kitty sets out to prove how much she knows - and gets one or two surprises. This is the sixth book about Kitty from the popular author Bel Mooney.

Kitty always seems brave and tough, but really she gets scared like everyone else. All sorts of things are frightening for her and her friends from monsters and ghosts to the audience at the school play. And one day Kitty finds out that even her older brother gets scared too and she can help!
