Calla's mum has never been normal. She's been known to go out in a lab coat and slippers and often forgets to perform basic tasks because she's been thinking about ducks. When a job offer arrives to study her beloved birds in the Amazon rainforest, Calla knows her mum has to go. Nervously, she agrees to go to boarding school. She quickly learns that trouble is afoot in this odd convent school. A mean new headmistress is imposing horrible rules and making everyone eat Brussels sprout cake, and the students are itching to revolt. As Calla makes new friends and gets drawn into their rebellious plot, she keeps waiting for her mum to call. She will, won't she? Exuberantly funny and brimming with heart, How to Be Brave is a riotous celebration of the power of resourceful girls, stories and the right biscuit at the right time.
