But Delderton Hall is a far more unusual and interesting place than Tally ever imagined, and she soon falls in love with its eccentric staff and pupils. Now she's even organizing an exciting school trip to the kingdom of Bergania ...although Tally never expected to meet the prince.

Then Karil meets a feisty English girl who brings the promise of adventure. But his country is under threat, and the prince soon looks to his new friend Tally for survival as well as friendship...
