What are the motifs in Whitney, My Love by Judith McNaught?

Friends and family are recurring ideas in the book. Whitney's mother died when she was a small child and her father is an unemotional man who does not know what to do with his wild and impetuous daughter. Whitney is pushed off onto her aunt and uncle who become to her the parents she has never known. Whitney is spoiled with every luxury a young woman can enjoy and given a debut into Paris society that rivals that of the other privileged ladies of her day.
