What is the theme in The Many Lives & Secret Sorrows of Josephine B by Sandra Gulland?

Belief in destiny is a theme. Rose is surrounded by fortune tellers and other mystical beliefs as a child and this is likely at the heart of her belief in destiny as it is foretold during her childhood. Rose, apparently fearing that she will never be married, seeks out the services of a fortune teller and is told that she will be unhappily married but will later be queen. On several occasions she laughs at the prophesy but apparently believes in it to some degree, especially when her marriage to Alexandre is so unhappy that it apparently fulfills the first part of the prophesy.
