What are the motifs in Jumping the Nail by Eve Bunting?

Dealing with money is a reoccurring idea in the story.

One of the major themes of this book is money. The characters all deal with money in different ways. For example, Dru shies away from money. She is content in her rented house, with her middle class lifestyle. She will not go to Mike's extravagant house because she does not want to deal with the upper class. She does not fit in with her rich classmates, who all wear designer clothes. Dru views money in a negative light since she sees many of her rich peers as mean-spirited and selfish. She takes after her father, who is not impressed by money and is happy in his life. She sees him as a sophisticated man whom she admires.
