What are the motifs in A Solitary Blue by Cynthia Voigt?

Love is a recurring idea in the novel. Voigt explores various concepts of love in A Solitary Blue, and in the contrast between Jeff's relationship with his mother and his relationship with his father, makes a powerful statement about true love and false, selfish love. When Jeff goes to stay with Melody in South Carolina, he blossoms around her warmth, and mistakes her passionate ways and her proclamations of love for the real thing.
