Binny in Secret

With her awful secondhand uniform and stuck-up classmates, Binny's new school is horrible. And life gets even worse when a storm damages the roof of her house, forcing Binny and her family to move to the countryside whilst it's being fixed. Binny, her sensible older sister Clem, and her rambunctious brother James (and his chickens) begin adjusting to life in the country. Then one of James's beloved chickens vanishes and Binny finds strange footprints in the mud. What kind of creature is lurking in the undergrowth?
