A boarding-school trip takes eleven-year-old Tally to a European kingdom bordering Germany during WWII, where she finds danger, adventure and a young prince in need of her help in this Eva Ibbotson classic.

1939, London. With war on the horizon, Dr James Hamilton makes the difficult decision to send his daughter to a boarding school called Delderton in the English countryside. At first furious, Tally agrees to go for the sake of her father. But she soon learns that Delderton is a place like no other. Here, the dancing teacher encourages them to be seeds busting into light, and the enigmatic biology teacher Matteo takes them for study walks at four in the morning.

Enamored of Bergania, a serene and peaceful country led by a noble king, Tally organizes a dance troupe to attend the international folk dancing festival there. At the Dragonfly Pool, she meets Karil, the crown prince of Bergania, who wants nothing more than ordinary friends. But when Karil's father is assassinated, it's up to Tally and her friends to help Karil escape the Nazis and the bleak future he has inherited.

The Dragonfly Pool is an exciting story of friendship and determination during the Second World War, from New York Times bestseller Eva Ibbotson, the award-winning author of Journey to the River Sea and The Star of Kazan.
