How does the author use metaphor in the novel, Veronika?

For Veronika, and therefore for the narrative, the new moon is a symbol of new life and new beginnings, of hope and of possibility in the midst of despair. The metaphor is suggested by the fact that the narrative includes references to such a moon when Veronika is playing the piano in Villete, her playing becoming an externalization and manifestation of her desire to live.
