What are the motifs in The Broken Bridge by Philip Pullman?

Family is especially important in life and in the novel. In the beginning, Ginny thinks that family is the most important thing; she especially wants the truth about her family because she thinks that truth will reveal her proper identity. She later discovers that she has some say in who she becomes. She later discovers that her rich imagination, intelligence and kind heart may be strong enough to mend the broken family ties between her father and his parents. Ginny discovers that she may never be able to mend the broken bridge between her mother and herself; this does not become a problem for her in life because to Ginny, the artist, her mother shows her how to paint and be true to herself.
