Katarina Mikhailovna Vassilieva has a secret. She spends most of her time online, talking to her best friend, Audrey, about the popular anime series Elf Forest, but Katarina (known to her friends as Katya) is more than an ordinary girl. She is, in fact, a princess: the future ruler of the small, little-known country of Lebedová.
One day, when talking to Audrey, Katya lets slip that she's a princess, and she invites Audrey to come and stay with her in Lebedová's royal palace during the winter holidays.
Audrey, an ordinary girl from Wales, is stunned by this reveal, but she eventually comes around to it. What girl wouldn't want to take an all-expenses paid holiday to a foreign country and live in a palace?
After a year of being friends online, Katya and Audrey finally meet face to face - but how will their relationship develop?
