Twelve days. Five kids. Many special effects. One giant mystery. Hayley Whelan has spent her whole life dreaming of making a horror movie – and not just the type of movie that kids make on their dodgy second-hand iPhones. When her grandma passes away, she inherits the money for a proper, grown-up camera. But before Hayley even calls ‘Action!’, strange things start happening¬ø Someone is sabotaging Hayley’s movie – but who? Why? And can Hayley finish her movie in time for the premiere? From Australia’s brightest new middle-grade talent comes this love song to movies, friendship and the summer holidays.
