What are the motifs in The Sixteen Pleasures by Robert Hellenga?

Home is a recurring idea. Finding a place to call home is a major theme in this book. Margot is constantly searching. She felt very at home in Italy when she was a teenager and visiting with her mother, but had to leave. She claims that the home she had in Chicago with her father and sisters was the only place that she could call home, yet she voluntarily left it.
