And inside the kingdom's Royal Palace is the Ballet School, where the Ballerinas-in-Training live, with their animals. The friends are delighted when their History of Ballet project is to study Eva Snowdrop, the famous ballerina. But Crys fears her secret will be revealed and she and her fox Pollux run away. Her friends must find them - but where are they?
Emerald Everhart was once a very famous and talented ballerina. Many years ago, one of her admirers gave her a perfume bottle of frosted glass. While Emerald owned that bottle, her performances were the best they'd ever been. Then, one day, the bottle was accidentally thrown away. From that moment, she never danced as well again. She has now dedicated her life to finding that perfume bottle - and the kingdom within it: the Kingdom of the Frosty Mountains. As she searches, she remembers the stories her admirer once told her - the stories of the Ballerinas-in-Training. She shares those stories in these enchanting books. Lastly, she asks that if you ever chance upon the perfume bottle that you please let her know. Her life just is not the same without it.
