What to read after How to Be Prime Minister and Survive Grade Five?

When Harper's dad becomes the prime minister he's terrible at it. He was thrust into the top job after a heroic boogie-board rescue of two kids (and a labradoodle) from a shark attack, but surviving government is proving hard. Their family is a laughing stock, and Dad disappears to a 'conference' – but he leaves his phone behind. With her little sister, Lottie, Harper must secretly take his place and decide on a new policy by the end of the week. She finds herself torn between ideas – should she ban plastic bottles? Or make weekends longer? Can she prove a kid can lead the country better than a grown-up?
