Minnie McGill is a Queensland girl living the 1970s Joh Bjelke Petersen era, a time of complex political paranoia machinations. Nine-year-old Minnie doesn’t see the complexities – only the simple fact of her plan. She lives for the baking world and soon enough she’s got a new book that’s going to be her road map to success. The Women’s Weekly Birthday Cake book has instructions for a hundred cakes and she’s going to make every one. But she’s barely into her second cake when her identical twin sister, suffering paranoid schizophrenia, puts a stop her to plans. As the illness shows its complex face to her, Minnie must decide whether to give up on her dream and look after her sick sister, or leave town in pursuit of her ambition.
