What is the theme in The Story of the Trapp Family Singers by Maria von Trapp?

Uncertainty is another theme in the story. There is a sense of uncertainty in every step of the way, beginning with Maria's first trip to the Reverend Mother's quarters. She questions whether she in trouble again. Once at the Trapp Villa, Maria is not sure how to behave. She daringly imparts opinions, but she is not sure of the effects of overstepping her bounds. As things progress, the question over whether the Captain will marry the Princess Yvonne or not nags at her. The reader does not know if this is because she is secretly infatuated with him, or because she wants to get back to convent life.
