A Middle-grade spinoff of The Princess Diaries, about the long-lost sister of Mia Thermopolis, Princess of Genovia. Olivia Grace is completely average. Or so she thinks. Until Her Royal Highness, Princess Mia Thermopolis turns up at her school one day and whisks Olivia away to New York City! But discovering that your father is actually the Prince of Genovia is quite a shock. Especially since it means you're a descendent of the Kingdom of Genovia, and a princess.
