Das Rätsel um die rosa Box

If Nanna could change her name, she would do it immediately. Her name means "the daring one," but Nanna never feels that way. She is rather anxious and doesn't believe she can do many things. Her classmate Milan takes every opportunity to make fun of her. However, when Nanna witnesses Milan stealing a small pink music box one day, the tables turn. Nanna gathers all her courage to find out why he did it. Stealing is completely unacceptable for Nanna, but when she learns that the box is a gift for Milan's deaf sister and that he is getting into trouble because of the theft, she helps him out of the predicament in an unusual way.
