Starlight

               I'm reading a book called Starlight, written by Malin Stehn. The book has 151 pages.                          The book is about 4 girls, Matilda, Julia, Jasmin and Nina, who were invited for a concert                     tour and can travel around the whole country. between the concerts they have to make                          important decisions, because Matilda's grandfather gets even before the last concert a heart                attack and is in the hospital, and Matilda did not know if she should go back home or if she                  should sing. The Main Character of the book is Matilda. 

            The word, that I didn't understand was involuntarily.
