The blabber mouth collection - Morris Gleitzman

Rowena Batts is always in trouble. It probably has something do with her quick temper - stuffing a frog into bully-boy Darryn Peck's mouth wasn't the best idea in the world. Neither was stealing his crazy cockatoo. But Rowena has a bigger problem. Her dad. Somehow she has to tell him that his revolting shirts and his horrific habit of bursting into song in public are even more disastrous than she is. And it's not easy talking your way out of trouble when you were born unable to speak . . .

Rowena and her dad rock from one batty but bittersweet scenario to the next, across all three books.
