Rose's life was wonderful: a loving mother, loyal friends, a rapidly growing fashion blog... But after the death of her mother in a car accident, everything changed: now she lives with her grandmother, whom she barely remembers, and learns to cope with the ridicule of her mean classmates at her new school. The only refuge is grandma's greenhouse. But strange things happen here: after discovering a mysterious light, Rose is sent back to events 500 years ago, where she is the servant of the most famous princess in history... who is awaiting trial. Now Rose needs to find out everything about the mysterious portal - perhaps it is the key to her own past.
