What is the theme in Mudbound by Hillary Jordan?

Family is a major theme in this story. In this novel, there are two types of families. The first type of family is the kind that loves one another, the one that sticks together through whatever might happen, and who survive hardships together. Two families fill this requirement in this novel in different ways. The Jacksons are clearly a close family. Hap is a strong, God-fearing man who works hard to care for his family and to save to someday buy a farm of his own. His wife is equally as strong, a woman who speaks her mind and works hard to provide as she sees fit.
