On the evening of the 800th anniversary of the founding of the small European kingdom of Colsteinburg, violence erupts outside the royal palace, throwing one family's life into chaos. After a coup in her country, Her Royal Highness, Fredericka Elisabetta Teresa von Boden don Morh (or Fritzi to her friends), wakes up one day no longer a princess. Stuck hiding in a suburban American middle school dealing with mean girls, cafeteria lunches, and teachers who don't understand (or know about) her unique situation, Fritzi just wants to go home to her kingdom and be a princess again. She turns to social media for help, but will her efforts work or make everything worse? With opposition forces trying to force her father's abdication from the throne, Fritzi discovers that being a true princess doesn't come from a title.
