Wife and mother, Harriett (Harry) Hill was on the fast track straight to the top when she decided to take a promotion as small school Principal, almost guaranteeing her a leadership role in the city at the end of her contract. After uprooting her family and moving to the outback, all Harry had to do was survive the small town of 1262 people, including its demon population. Where once Harry's largest complication had been managing her ambition and her young family, her life quickly changed when she discovered she was the only person who could keep the demons from the Key to Hell, which had been hidden in one of the remotest locations in the world. In a town where half of the local population, and most of her students, might be demons, Harry must work to keep the school running, her family happy, and the whole of human kind safe.
