In The Dragonfly Pool, in 1939 Europe, Tally is apprehensive about attending Delderton, for she has many fears about boarding school. But Delderton proves to be a wonderful place after all, even allowing her to form her own dance troupe. She also makes fast friends with Karil, a crown prince. But then Karil’s father is assassinated, and Tally vows to help her friend escape from the Nazis.
