Rosie can't wait to move to her Great-aunt Rosamund's castle in the Scottish Highlands. She's visited there many times but now she's going to actually live there with Mum, Dad and her little brother, Luke, while Great-aunt Rosamund is away travelling.
While she's exploring the castle Rosie finds a secret note from her great-aunt. It's written in invisible ink but that night the heat from the fire in the Great Hall reveals the message: Look for the Little Princesses . . .and always remember to curtsey and say 'Hello'! And, sure enough, when Rosie says hello to the princess on the beautiful Persian rug in her bedroom, she is whisked away to ancient Persia on her first adventure!
The kingdom has been overtaken by Abdul the evil genie, who has stolen Princess Azara's voice and imprisoned Azara's father in the palace dungeons. Will Rosie and the Little Princess be able to defeat the genie and restore peace to the land . . .?
